Ft. Walton Machining: Company Profile

Ft. Walton Machining – a company profile

I had the opportunity a few years ago to visit Ft. Walton Machining and to meet its owner, Mr. Tim McDonald Sr., a great business man with some amazing toys: One amazing machine facility, and one really cool WWII-era T-6 Texan training aircraft. Unfortunately I didn’t get the opportunity to spend more time with him before his passing in 2010.

I decided to return to Ft. Walton Machining, for a better look at the equipment and teamwork that makes company so successful. It really is an amazing company and has built an incredible reputation that has landed them some of the best contracts in multiple industries. Timothy McDonald Jr., runs the operations center, and agreed to see me and show me around.

Ft Walton Machining Front View

General Profile

Ft. Walton Machining was founded by Mr. McDonald in 1997. Since then it has been housed at 2 locations, and has increased from 35 employees to more than 210 team members at this time. The company houses more than 50 machine spindles, including fifteen 5-axis milling stations. They supply major corporations regularly with various components, including names such as Boeing, Gulfstream, Locheed-Martin, NASA, various military units, oil production companies, and more. The most exciting contract that I was permitted to mention was that Ft. Walton Machining is the largest supplier of F-35 airframe components in the world. Awesome!

The 65,000 SF Manufacturing facility is divided by process as follows:

  • CNC Milling
  • CNC Lathe
  • Electrical Discharge Machining (EDM)
  • Engineering
  • Fabrication
  • Finishing
  • Lean Manufacturing
  • Quality Assurance
  • Waterjet
  • Welding

One thing I learned since my last visit was that the company has purchased another facility in order to expand its materials finishing division. Now that location handles 100% of the finishing, giving more room to the machining facility, and streamlining their overall process.

The 42,000 SF Material Finishing Division facility is composed of process divisions as follows:

  • Anodizing
  • Assemblies
  • Chem-Film
  • Passivation
  • Prime & Paint
  • NonDestructive Testing (NDT)

This new addition includes a conveyor drying paint line, a gas curing oven, paint booths, and a PLC controlled custom chemical finishing line.

Manufacturing Walk Through

After I hefted out from under the enormous non-disclosure agreement the company’s kind receptionist ‘encouraged’ me to sign, I was issued a guest pass, and reacquainted with Timothy McDonald, Jr., who took the time to chat with me about this article, and to furnish some background on the company that I didn’t know. McDonald is the Program Manager, as well as the company’s Secretary/Treasurer.

It is difficult to get a grasp of the scope of the facility without a map; it’s huge. It’s not to the magnitude of say the Lockheed facility in Marietta, with cars on roads with named streets inside the oversized building, but you could spend a week at Ft. Walton Machining trying to figure out where everything is. A fun question to ask is, “what’s beyond that wall over there?”  The answer was usually “more!”

Immediately I happened upon these beautiful oil well drill drive shafts. 4’ long and 8” in diameter, with the finest looking bearing journals. I asked about the processes involved and was surprised to find that while the entire part was turned, the journals were not ground. McDonald went on to explain that they are roller burnished, using a peening-like process that rolls the journals into submission under great pressure [30,000 psi], delivering superior bearing strength and trueness. McDonald noted “As you can image, being a mile down a hole, the components will experience a great deal of vibration. That ultimately converts into fatigue stress and cracks, and this process extends the life of these shafts significantly.” I was however not permitted to take one home. That’s my kind of art!

Ft Walton Machining Oil Well Drill Shafts

The precision on the drill shaft turning and burnishing is held to 0.0005 in.

McDonald continued “If something goes wrong down in that hole, it costs $4 million an hour to pull that drill. That’s when feelings start to really get hurt, so you have to make sure your product is spot-on correct.”

As we moved, what I could observe was numerous aircraft parts including flight critical components for C-17’s aircraft and CH-47 helicopters. I was escorted through all the departments and given time to chat with the team members. We discussed everything from manufacturing processes to strategies, most of which could not be mentioned in this article. One topic that was approved was the oil drilling components, which turned out to be really interesting as well. The team explained, in detail, the ingenious strategies used in oil well drilling, as well as the processes used to manufacturing these tools. It was pretty awesome.

I found a dedicated team of individuals that know their machinery and products. When engaged about different approaches to specific components and techniques, everyone was eager to share their experiences and methods used to successfully get the components out the door. Everything from their adoption of High-Speed Machining to advanced materials was discussed; where things worked and where they didn’t. When I’d ask about the tolerances of a component feature, the technician’s would stop to explain what these were, and various strategies that paid off in maintaining them.

The two silver boring bars in the turret are 2 in. solid carbide DeVi bars. These are tuned to bore chatter free at extended depths. I just priced them out at over $2000 USD each, plus inserts. Pricey; I’ve never used one, but the industry swears by them. “We had Iscar make us a 4 in. slam drill that will chew metal like you would not believe. It took us 4 months to get it. It will pop a 4 in. hole, 5 in. deep in about 5 minutes. That’s a massive insert.” McDonald said. The technician pulled the turret down for me to inspect. “The savings were instantaneous.”

Ft Walton Machining CNC Water-Jet  Ft Walton Machining Inspection

While discussing the merits and problems with waterjet, McDonald mentions, “we used it once to cut 8 in.-thick titanium. We called the manufacturer and asked how it could be done. They said you couldn’t do it; that presented a challenge. It took 28 hours, but when talking titanium at 80 bucks a pound, it was worth it in the end.”

I was able to inspect some beautifully crafted components. High precision, small components and very large scale multi-process assemblies. Unfortunately I was only permitted to show a small sample for the sake of security.

Ft Walton Machining Multiple Processes

This Navy ship exhaust duct was one component that was extremely tedious to manufacture. The processes involved include sheet metal fabrication, water jet, welding, and finish machining. The mating flange surfaces have to be flat within 0.005 in. The team welds the processed components first, and then after substantial blocking, the custom jigs are removed, and the flanges are surface milled within tolerance.

Another really nifty gizmo was the Iscar Matrix tool vending machine. Sounds funny, right. Instead of Twinkies, this cool cabinet dispenses inserts. The team members enter their employee password, and then scan the scan bar on the job order. The Matrix is tied in with the ERP system, and after the scan is made and the insert is selected, the cost of the insert is automatically applied to the project for cost analyses. The vending machine then unlocks and opens the appropriate drawer. “It’s like a giant Pez dispenser”, one technician said. McDonald added “When the last insert is removed, an email is sent to the tool crib notifying them that the drawer needs to be restocked. We never run out of inserts this way. These are used throughout the industry in various ways, we use them for inserts… and subsequently the occurrences of having ‘missing’ cutters has dropped dramatically.”

McDonald escorted me through every area of the shop. As we passed by their Blue Streak department, I pointed to the sign and asked about it. He told me that department is comprised of machines that are ready to work with low volume to handle their client’s emergency needs. This way when a problem arises, they don’t have to shut down an operation to accommodate the need.

As we were wrapping up the tour, Glenn Larson, Ft. Walton Machining’s software guru caught up with us and we began discussing some CAM issues and strategies in parts as McDonald took us by components and tooling. We looked at their R&D changes to the AccuView contact lens palettes (my wife wears those!), and the intricate detail required to accomplish their needs.  Moving along we passed by a FARO portable CMM unit and the discussion turned to inspections, and how they use it when they can’t check the parts in the QA Lab. They mentioned that a laser scanner can be attached to the unit and McDonald added “We are quite interested in light scanning, it’s the next wave and the direction we are going”.

I wanted to give their Haimer Power Clamp a try. The unit heat expands the milling collets in order to fit the tooling inside, and then cools the collets back down which clamps the tolling down tight. No screws, no clamps. McDonald said it absolutely kills the runout associated with collets. They showed me one application where they needed a small diameter tool in this arrangement. They had a tool, heat shrunk into a collet, heat shrunk into another, and into another.

After making it to the QA lab where all the components are inspected, the pair noted that the part being inspected had a variable radii developed in Autodesk Inventor with some special love from Glenn Larson’s team added in. McDonald noted, “Once we’re done welding, we verify the positions before adding that bottom fillet radii in the mill. The top surface has a 0.002 in. tolerance and is a bit tight to hold throughout on a mill. What we’re going to do is make a special arbor on the lathe; we’ll mount two of them to it to counterbalance, and turn the top profile. This part is very complex in the sequencing we had to go through, but I’m happy with it thus far.” The two were confident [if not a wee bit squeamish], as they reflected on the prospects of the final surface turning process. That’s a lot of time and money invested in a process that only gets more difficult and precise. By the time of this article, they should have completed that process. I’d love to hear how it went.

One thing I found odd but didn’t inquire about was that the company doesn’t do any plasma spray buildups. They outsource the process to favored companies when needed.

My thoughts

I always enjoy hearing about the progress of this company ever since I first met them and toured the facility years ago. Their continued expansion and successes have stemmed from staying on top of the technology, knowing the trade, thinking far beyond the norm, and building exceptional relationships. I never think twice about referring companies to them to handle any component manufacturing needs.

It’s an awesome team and facility, and I’m going back as soon as they get over my excitement during this past visit.

Check back in soon for the follow-up interview article with Tim McDonald and Glenn Larson, and their discussion about the company’s successful transition to CATIA.

What Makes A Maker?

The “Maker Movement,” I’m sure you’ve all heard of it, but what exactly is it? I don’t know if there’s actually an official definition, but I think of it as the tinkerers and hobbyists of the past, with access to a whole lot more knowledge and technology thanks to the internet. Now even this is a very broad definition, but I guess you could split it up again into a couple of big categories. Those that make for themselves, and those that make for, or with others.

It has always blown me away at just how many people are happy to selflessly contribute a huge proportion of their free time to sharing things they’ve learnt with others, for free, using the internet. I consider myself to fit into the “maker” persona, but I often feel the guilt of just how lazy I am when it comes to sharing my knowledge with others. I owe a lot of what I know, to the internet and the people who contribute their knowledge, but yet I give so little back. I made a conscious decision earlier this year, to try to rectify that, and that’s when I started writing articles for Design and Motion. My wife and I live a pretty busy lifestyle, so while the fortnightly posts can occasionally become a bit of a chore, the sense of satisfaction I get when I finally hit the “publish” button is a magical thing. Kind of like that one shot you hit in your last terrible round of golf, which felt so good that you know you’ll be back to play again. This to me, is the essence of what fuels the maker community. People get satisfaction from sharing what they have made with others.

Now there is a dilemma that often arises here, when you want to move from making for fun, to making for money. Many have battled with the balance of how much to give away, versus what they should protect and sell. Creative Commons and the open-source movement had, and still has many scratching their heads, wondering how on earth a business can give something away for nothing, and still make money.

One topic that I often think about, is the future of makers. If we go back in history, humans went from being fairly self-sufficient makers, to fairly dependent non-makers. We outsourced our making to mass-production. If the futurists of today are correct in their predictions, self-making on a massive scale will return to the mainstream and the industrial revolution will effectively be reversed at some point. So my question is this:

What should traditional manufacturers do, to future-proof their businesses?

I don’t have an answer for this, so I thought I’d put it to the maker community from Autodesk, along with some of my other questions.

When I was a student, my visions of my future self always placed me in someone else’s company, designing things to be made for someone else. It turned out, that I have ended up spending a fair chunk of my career so far in self-employment. I often wonder how things would be different if I had focused my energy as a student, on working towards being my own boss. The reason I say this, is with today’s channels for dissemination of information and knowledge, along with incredible accessibility to technology (you can buy just about anything online), small scale manufacturing for a large market is a very real option to make a living. The internet allows people that have “the knack” to learn more about anything they want to, purchase just about anything they need, and sell their ideas, products or services to a potentially huge number of people.

So another question:

What should we be doing to equip today’s students, to go down the path of being a maker, regardless of what sort of scale it ends up being on?

I believe that teaching students to digest and assess information critically, regardless of source, is just as important as sharing knowledge of particular topics. Ask just about any ex-student how much of what they learned in their studies, they actually use in their jobs. Most will say very little. Now don’t get me wrong, I believe that all knowledge is valuable, whether you use it or not. With increasing variety and specialization though, the most valuable skills are being able to learn new things quickly, whilst maintaining rational thought and critical reasoning.

I spoke above, about the satisfaction that can be gained from sharing knowledge with others, which comes naturally for many makers who are proud to show off their creations. The other big maker satisfaction though, is simply just the satisfaction in creating something. Typically, when making something for one’s self, the end result is often a prototype of sorts. Something which was made with the materials that were readily available, using methods that were not necessarily very efficient, but which got the job done eventually. Even though the end result was not arrived at in the most efficient way possible, the satisfaction was still gained. When moving from making for one’s self, to making for others, efficiency quickly moves to the forefront. In my experience, a lot of tinkerer types don’t have a natural ability to find efficiency, or a desire to replicate their making in any kind of volume. Bear with me here, I do have a point, and I’ll get to it eventually.

A few years ago, I was discussing entrepreneurship with my uncle in a broad sense, and various examples of companies came up. We discussed how they differed and what we liked and disliked about each. He told me of a theory he had about a formula for a successful business. He mentioned “the 3 guys (or girls)” that need to be involved. Here they are:

“Ideas Guy”

Ideas Guy never settles for status quo, he is always finding better ways to do things, and constantly frustrating his friends with his practical solutions to everything. “How has no one thought of that before!?” is a common statement from his friends. While he is always asking why something can’t be done a better way, he doesn’t often know exactly his solution will be achieved.

The Ideas GuyThe Ideas Guy (Credit: Sebastiaan ter Burg)

“The Geek”

The Geek is a detail guy. He agonises over technicalities and details and is sometimes mistakenly perceived to be negative or a party pooper, by finding technical problems with proposed solutions. Having said that, he’ll expend a huge amount of energy overcoming the challenges to make an idea work.

“The Other Guy”

The other guy is a very flexible persona who can sell sand to a Saharan, but also has a good feel for legal matters.

Now obviously this is a rather flexible arrangement that could have different numbers or types of people with different strengths. The key however, is that to commercialize a product, you really need a team.

So how do you go about finding this team?

Makers are an interesting bunch, some of them manage to play both the Ideas Guy and The Geek. These guys are off to a head start and often manage to get themselves started using a crowd-funding platform like kickstarter or Indiegogo to get their product off the ground.

For others, they may naturally have the team in a group of people they know, and can quickly get to work turning their elegant solution for a problem they had, into a solution for others who are willing to pay for it, in similar ways.

The vast majority however, are the lonely makers, who make for themselves, quietly share their knowledge/recipes/instructions fairly inconspicuously through blogs and forums, and only dream of one day being able to sell their product. It’s this group that I believe we need to help the most, as students, to find their team.

This brings me onto an idea that I had which would somehow combine the various aspects of commercialization of an idea. We already have great resources for makers, in a number of areas:


You can learn about just about anything online. Whether you’re browsing a maker website like Instructables to learn how to replicate someone else’s idea, or studying towards a degree in a classical subject like physics through an online university, there is no shortage of knowledge that is accessible for free. logoInstructables – a website dedicated to makers


Autodesk are blazing trails when it comes to giving away design software for free, to allow anyone to explore their ideas in an almost limitless number of ways. While all Autodesk software is available to students at no charge, others are even free to anyone. Products like Fusion360 (free for enthusiasts), let people create 3D digital models of their ideas, simulate them, and even run machine tools to create the physical end result. GrabCAD is another company that has provided an amazing free platform, which allows people to share their digital models with others. Why design a certain sub-component yourself, if someone else has done it for you?


If you can’t get access to machines to bring your ideas to life, why not build a machine yourself? Many websites have are dedicated to open-source designs for machines which can be used to make just about anything. Components for making things are also readily available through a huge number of maker-focused websites. An example of this is BuildYourCNC.


Turning prototypes into saleable products requires money, and borrowed money for unproven ideas can be hard to come by through traditional channels. Online crowd-funding platforms like Indiegogo make fundraising for commercializing good ideas relatively easy. Potential customers effectively fund the development of products they like the idea of themselves.

So what’s missing?

“The Team” of course. While sites like allow companies to quickly find freelancers for contract work, I’m yet to see a site whose primary focus is in getting The “Ideas Guy”, “Geek”, and “Other Guy” together to commercialize a great idea. I’m not usually the Ideas Guy, but there’s my idea. Can someone please make it happen already….?


DIY CNC Machining from Scratch | CAM/CNC 101

CAM/CNC 101 – The software side:

For those that have never had any exposure to CAM (computer aided manufacturing) and CNC (computer numerical control), the principles of it are as follows. A 2D or 3D software representation (model or drawing) of a component is interpreted by some clever algorithms in conjunction with some user input inside a piece of software known as a CAM application. These algorithms generate paths in 3D space for a cutting tool to follow.

3D Toolpath in InventorHSM3D T-Splines Freeform CAM Model in Autodesk InventorHSM 2015

Once these paths have been generated, another piece of software called a post-processor converts the paths into another form of code which can be read by a controller built into the CNC machine. This is often of a format known as G-code. There are a huge range of standard G-codes which define different types of movement on the machine. For further detail, see Wikipedia G-Code definition.

Controllers and Software:

I’m going to skip over the CAM step for now, as this is a huge topic on it’s own. I use the Autodesk HSM (high-speed machining) solutions for all my CAM work and I’ll follow up with a post on InventorHSM soon.

In a commercial CNC machine, the controller is usually a self-contained unit with a control panel (see an example from Haas below), that the machine operator stands in front of and has the ability to have control code inputted directly from the panel, or be “piped” to the machine from a computer with CAM software (known as DNC).

Haas CNC ControllerA Haas CNC controller attached to a Haas Vertical Machining Center (3 axis Mill)

For hobbyists, or others on limited budgets, these controllers are very expensive, but other options exist. A common route is to emulate the machine controller with a software based solution that uses a normal keyboard and mouse for input and a computer monitor for visual feedback. There are quite a few options here, but the popular ones are LinuxCNC (formally EMC) and Mach3 (Windows based.) LinuxCNC is a free open-source solution, while Mach 3 is a commercial product. A few years ago, having had a look at both, I decided to give LinuxCNC a go given that it was free, and found it to be brilliant.

GCode program loaded in LinuxCNC machine controller.LinuxCNC Machine Controller with NC Program Loaded

 The flexibility that these controllers provide are amazing. LinuxCNC supports up to 9 axes of motions and has support for various kinematics systems, including robotic arms. I have seen examples of LinuxCNC running hexapod robotic spiders. And this is a free open-source package! To use it, once configured, you simply load your NC code file, review the toolpaths in the preview, check that your tools are in order and hit the Start button. The motors whizz into life and the cutter starts to make chips fly. All going well, you end up with a finished part.

Calibration / Tuning:

To get LinuxCNC to work with any machine, there is a process of set up and calibration that has to be performed. With an enormous variety of motor types, PC specifications, sensors and switches that all provide inputs and outputs for LinuxCNC, you can imagine that hardly any 2 setups are identical. Luckily, the calibration and tuning process for the motors is fairly straightforward. You may remember from Part 1: The Mechanical Conversion, that we calculated the distance that each axis would move for each “step” that the controller sent to the motor. That data needs to be fed into LinuxCNC so that the software knows how many steps to send to the motors, to move the cutter to the correct position.

Configuring X Axis in LinuxCNCStepper Motor Configuration in LinuxCNC Step Configuration Wizard

Step Configuration Wizard in LinuxCNC provides a really simple way to input the required information. After setting up the motors, limit switches, emergency stops and other I/O can be configured with a straightforward pin map for the motor controller. I used a Geckodrive G540 which has preset options installed in LinuxCNC by default. In Part 2: The Electronics, I talk more about the role of the Geckodrive G540.

With all of this set up, the next step was to test the 3 axes and adjust the tuning to get the motors running really smoothly. A trimpot for each of the axes is provided on the G540 stepper driver that allows fine motor tuning. It’s simply a matter of running each axis and turning the screw backwards and forwards until an audible “sweet spot” is heard. Following this, accuracy checks needed to be performed. There are many ways to achieve this, but the process is basically about checking that the machined dimensions of a real component match the modelled dimensions as closely as possible. I often use drilled holes to check this. I drill a hole at one end of a piece of material, and then move a fixed amount in one direction and drill a second hole. Next I measure the center distance between the holes and compare with the commanded distance. Finally I move the axis back in the opposite direction and measure the error between the two. Repeating this a number of times and averaging the error gives me the backlash in an axis.

Sherwin Perez Leadscrew render from GrabCADLeadscrews modelled and rendered by Sherwin Perez, as posted on GrabCAD

Backlash is basically the amount of “slop” in a mechanical system when changing direction, due to clearance in transmission of drive or other “looseness.” There is usually some backlash in any system, and the goal is to reduce it to as much as possible. The remaining amount can usually then be dealt with with software backlash compensation. The way this works, is that you program a known amount of backlash into the machine controller, and the machine compensates for this amount every time the motors reverse direction. This is surprisingly effective. My mill has approximately 0.3mm of backlash in the x-axis, and with backlash compensation in LinuxCNC set up, the resulting backlash error in the part is closer to 0.05mm. Most of my backlash is due to trapezoidal thread leadscrews that drive the 3 axes. I am in the process of designing a conversion to replace the lead screws with much more accurate ballscrews that have close to zero backlash. I’ll make sure to write an update post to cover this.

Giacomo Calzoni Ballscrew renderBallscrew modelled and rendered by Giacomo Calzoni, as posted on GrabCAD

In my next post in this series, I’ll cover the first parts that I machined and the issues with software step generation. I’ll also talk about how I overcame this issue and the dramatic improvement in performance that was achieved through the use of a $180 bit of hardware.

’til next time….


National Manufacturing Week 2014 – Sydney, Australia

The CADGroup Booth at Manufacturing Week, Sydney

Cadgroup Booth at National Manufacturing Week 2014

I was lucky to be invited to National Manufacturing Week in Sydney this week to join the CADGroup guys in their booth at the show. They have recently been appointed as a reseller for the Autodesk HSM CAM products in Australia. Talking to them about the local manufacturing industry revealed some surprising details. The general opinion was that there tends to be a lot of fabrication, but not a lot of machining and component manufacture. I was initially skeptical, until I started to walk around the trade halls and have a look at the various companies displaying their products and services. After doing a full lap of both exhibition halls, I figured that there must be a 3rd somewhere. Where were all the CNC machines!? Not a single CNC mill or lathe in sight. The closest I could find was the Multicam stand who sell various routers designed and built in Australia. Multicam Router

Multicam booth at National Manufacturing week 2014

All the other NC gear was for profiling, waterjets and plasmas at every turn. I was very disappointed. Could this really be the case? If I find a 3rd hall somewhere, I’ll give an update, but I had hoped to write this article about all the wonderful VMCs and mill-turns on display, and now I’m just going to have to talk about 3D printers instead…

Those “other” machines….

Having followed 3D printing for many years, I can’t say I get excited about watching hobby machines turn plastic filament into little trinkets anymore. There must be a large group of people who do however, as there are at least 10 small scale 3D printer distributors flogging their wares within a stones throw of our booth here. After a cursory glance at each, I stumbled across an additive manufacturing machine that did get me excited, a laser based, metal powder fusion machine. Renishaw have a really good name for CNC touch probes and coordinate measuring machines. Now they build metal printers! They had some beautiful samples on display printed in Titanium and tell me that the strength properties of the material are similar to that of the cast equivalent.

Freeform bodies and Direct Edit.

If you’re a follower of Design and Motion, you would have noticed that we’ve been getting pretty excited about the new Freeform and Direct Edit tools in Inventor 2015. If you happen to be in Sydney, CADGroup’s Technical Head, Deepak Maini will be giving a live presentation at the NMW show on these new tools, as well as some really good stuff on large assembly management and Configurator 360.

By the way…

The first day at the show was a little quiet, so I thought I’d try and break Inventor HSM, just for fun. I created an adaptive clearing toolpath for an entire tractor tyre with a very detailed tread pattern. After a lot of chugging away, I ended up with a toolpath that would run for 42 hours according to the simulation statistics. Now of course you’d never actually run this code, but it was fun to see if I could push the limits of the engine. It completed the task with no issues which was great to see,.

Autodesk Inventor 2015 Sheet Metal packs a punch

Autodesk did a bang up good job on the enhancements to its manufacturing product line. Autodesk Inventor 2015 received a lot of important attention. Following up with our recent “What’s New in Inventor 2015” and “Free Your Forms” posts, we continue our deep dive series with some detail on the Sheet Metal enhancements.

Punch Across Bend

Punches are now applied ‘across bends’. This is a bit misleading, as the punches are really wrapped around the bend.

Inventor 2015 Sheet Metal Punch Across Bend

Inventor appears to accomplish this by applying the punch to the flat pattern in the background. This becomes evident when viewing the flat pattern and find the punch geometry shape laid out across the bend there.

This feature is helpful when you need to make punches at a location in the flat sheet before fabrication, but not after. Areas where manufacturers need the ability to press or punch a shape after forming will have to wait a little longer for that functionality.

Window selection of Multiple Points to Place a Punch

Inventor’s default behavior is to apply the punch to any points within a visible 2D sketch. The interface waits for the user after selecting the defaults. Windowing the sketch will remove the default selection and pick any point as well as sketch geometry endpoints that are within the window.

Use Cut Normal in the Cut Dialog Box

The Cut Normal option is added to the Cut dialog. This option projects selected profiles onto the sheet surface and then cuts perpendicular thereto.

Inventor 2015 Sheet Metal Cut Normal

In the image above you can see the difference between Cut Normal on right and Cut Across Bend on the left. Each sketched rectangle is 1.0 units tall. The Cut Across Bend is applied directly to the unbent sheet and then bent; it measures 1.0 units tall in the Flat Pattern.

The Cut Normal projects the sketch to the bent sheet face, and then cuts perpendicular through the sheet. The sketch plane angle is 45°; In the Flat Pattern, this feature measures 1.343 units tall.

The catch here is that Inventor projects to the inside of the bend (opposite of the sketch) and then cuts outward. This appears to enforces the ability for a 1.0 unit tall object to pass through the cut.

A-Side Definition Command Added to the Flat Pattern Panel

Inventor now allows users to define the A-Side of a sheet metal part. This command permits the sheet metal component to control the punch direction.

Inventor 2015 Sheet Metal A-Side Command

Inventor’s new functionality insists that an A-side be selected once the Flat Pattern has been generated. The Flat Pattern command will select an A-Side if users do not. Once selected, the A-side can be changed or deleted, but only by deleting the Flat Pattern feature first.

Unfold/Refold Imported Sheet Metal Part with Zero Radius Bend

Unfold/Refold command allows selection of zero radius bends and flatten zero radius bends when a flat pattern is created. A new face is added to accommodate the Unfold operation based on the user defined K-Factor. After Refolding these references remain.

Additional Enhancements

* Flat Pattern conversion prompts are more accurate

* Folded parts in the browser show EOF (End of Flat) instead of EOP

* Bend Edit dialog automatically expands to accommodate longest property name

* Flat Pattern dialog now includes an orientation rotation angle
