interesting process , i can see this taking of in the hobby world to make parts for steam machine boilers and stuff like that , that is if you can do these things on say a grizly G0704 running cnc , doesnt seem to make a lot of noise either wish is a good thing for me (hobby room in my spare bedroom of a apartment complex ) i myself would love to find out if you can make vellocity stacks using this , even if you would need to make them in two parts its still nice
No good reason to do this instead of just milling a stronger lighter part out of raw stock. It'd be MUCH faster, more consistent, easier to program and adjust, and it wouldn't leave you with a part that's warped and stressed to near-failure. Whatever money you're saving on material you're paying for several times over in wasted power running the machine longer, and lost productivity by tying up a machine for an hour per part, instead of 5 minutes per part.
Of course it's slow; the process is in its infancy. Consider how pathetic the first laser cutting machines were. Or Waterjet? Plasma? 3D printing in metal? Even CNC was a joke at first; it could not match the rigidity, accuracy and sophistication of high-end manual machine tools.
It is really expensive to cut something that is typically sheet metal formed from raw stock in a mill, much more than power costs. The amount of steel/aluminum needed would be a fortune. The waste is enormous, would wear out tooling constantly and would take a similar amount of time to make. Plus many complex fixtures would need to be made to clamp the part in place, and the larger the panel gets, it becomes impossible to machine with precision due to it vibrating on its cantilevered edges. Practical applications for this tech can be extremely useful for low volume car panels with mass customizability; think exotic cars. It also has applications for making biomedical devices or other low-volume, high precision manufacturing applications (Think metal implants for knee replacements, etc). Creating complex outer panels for plane designs that would be impossible in conventional die press operations would be a big plus. The automotive industry currently uses this in their prototype designs. It is so praised that Ford has even patented many technologies to improve its effectiveness. Die presses are better for mass production because of speed, but historically, prototypes panels could only be made after purchasing +$100,000 die sets. If it did not work, sucks to be you, they were screwed out of that money. Plus the 3-6 months it takes to make them. This allows prototypes to be made instantly once the machine has been set up and calibrated property. A one-time investment of money and time. If the material properties are defined before the operation, sheet metals can beneficial structural characteristics for their applications vs conventional milled stock. The amount of rolling creates a large amount of strength along the rolling direction of the steel. Plus, any coating or galvanization can be applied beforehand. Getting an even coating would be EXTREMELY difficult after the part has been machined
To bad we lost a generation of highly skilled people who in WWII could hand form parts like this. Now we need a machine to make these parts, sad. Lucky we do have a small highly talented group of skill craftsmen and women that can skill do this work and carry on the talent. We need to put people to work not machines.

Nice and clear! Where do you get the tool bit for this?
Bro, where did you get the table for different sizes of sheet metal?
Editing, people. Editing.
It was 10 years ago mate.
For what kind of things do you make if you're using SPIF?

How about doing this on lathe?
Someone can help me to know why the forming angle in Incremental Forming process is greater than all other process?
could you tell me the way to purchase the tool for this type of forming process?
you can make it by yourself.... it can be easily turned on lathe machine....
thank for your information.. It is very much useful...
im a first year mechanical engineering and i dont get it.
It's just stretching the metal with a stylus.
Now, I am starting in third year MEE now... Those major subjects are so hard.... :(
