Robotic Incremental sheet forming

- Robotic incremental sheet forming is a quiet interesting approach of deforming metal sheets in a wide spectrum of possible shapes.
There are many interesting business fields just like : moldmaking, productdesign, architecture and many more.
The future of production is going to be parametric !

It's funny this is a new concept. It's more similar to ancient manufacturing methods than modern!
Many of new concepts are based on old. Robotics and CNC just allow for less labor, flexibility, consistency and repeatability.
the first sailors used to weld their ships with lightning strikes, many things never change
I saw an even cooler process where they had 2 robots one on each side of the sheet working in perfect sync.
this is nice to make custom bodywork
Did Desktop Metal license this from you for their G15?
No :)
Looks great. Are you using a ball tracking 3d toolpath to program it? What percentage of spring back are you seeing?
No just using a ball pin for deforming and different strategies for programming. Never scanned the springback.
But possible to scan it and give a feedback to deformation strategy to get the planned result.
Few questions, how this compares to hyfroforming? In terms of manufacturing lead time, precision (profile tolerances of the resulting surface) bend radiuses dimensional control, finished surface roughness. I come from the aerospace industry and tolerances and roughness are a big deal. I ca see some marks on the finished sheet surface.
Hy Mauricio, in comparison with hydroforming you are completely flexible in terms of shape and dont have to premanufacture anything before. This deformation of the sheet can take between 20-50min . Depends on Speed and Accuracy. The precision depends on the ball tip you are using for the deformation. Im using 2 diameters for now 10mm and 20mm.
There is a springback in the material, whichI think can be avoided by a second round of deforming or using sensor for calculating the springback for each metal and thickness and reinvorcing the process to deform deeper so that the final result fits the shape you want. In terms of roughness and marks, there are no marks on the shape . its just the oil which shows up in lines whre the tip was moving. If the Tip is gliding smoothly on the shape with oil underneathand you will have no marks if the depth movements are little enough (
It's amazing how there is no support and the sheet only stretches locally. One would think the whole thing would deform upon pressure 🤔
I mean, it's held on all sides.
what is the duration compared to traditional press molding?
This shape takes approx. 30 min . not really compareably to traditional press molding.
It is good. what will be the maximum SS material thickness that can go up to in this process?
I was testing upto 1.5 mm as I remember
Maybe 2 mm
which company makes this robot?
Kuka this bits are used in some ride in theme parks.
Hydraulic press is still efficient and time saver
its a manufacturing technique without the use of any mold
That robot consumes a lot of energy to form 1 panel.
Compared to mass production yes according to one piece yes, but not in terms of single piece production or small series.
WHY DIDNT THINK ABOUT THIS?
