Nissan Die-less Incremental Forming

"Nissan Motor Co has developed and put into practical use ‘face-to-face die-less moulding’ that forms body panels without using moulds. The Japanese automaker says that in future, it “will use this technology to consider the commercialisation of after-service parts and repair parts for older cars.”
The opposite or dual-sided die-less moulding methodology involves a robot equipped with a rod-shaped tool using the incremental moulding technology in which the panel is gradually deformed to form the moulding tool on the opposite side. It is a construction method that can form more complicated shapes. The method of forming while linking opposing tools is difficult because it involves controlling two tools, and thus far has been considered difficult to put into practical use.
Nissan says it succeeded in putting it to practical use by combining accumulated knowledge in the field of production technology possessed by the company's production technology R&D Centre with the research results of tool materials from the Research Laboratory."

Hand forming techniques, but with computers and robots. Great for prototyping.

[@krusher74]

you cant form like this my hand. how is apposed point pressure done by hand?

[@douggolde7582]

@@krusher74 Think ball peen hammer on one side wood buck on the other. Also like an English wheel. Both classical hand techniques for metal working.

Is the tool rotating

[@Me30404938398]

Yes

those look like panels for old Datsuns

[@chethanslthippeswamy]

how is this going to replace traditional metal stamping in factories production line? , the turn around time is more than 30 minutes compare to stamping which take less than 1 minutes, i struggling to understand this.

[@praveenkonka-vt4qs]

Incremental Forming is suitable only for low volume production. If u need 50 such components then traditional stamping costs more due to component specific tooling.

[@carramrod8232]

Prototyping as well

[@ronblack7870]

often manufacturers need 1 off parts of sheetmetal for prototypes to test fit and other things. 3d printing can't do that well.

[@krusher74]

thy dont say it is. it “will use this technology to consider the commercialisation of after-service parts and repair parts for older cars.”

what is the point exactly? After their robots are done with this work Fiat produced already 50 complete cars...

[@samuelmendoza9356]

I think with the combination of 3D CAD, they can form variety of parts without machining the dies. Like, they can make variety of body panels with little to no change in tooling. Not worth the usual serial production, but when making the panels for older ones, whose tooling is probably gone, this would be worth using it.
Plus, rapid prototyping. I can see them choosing this instead of 3D printing. The latter needs extra process that involves a pressurized chamber just so the sintered 3D print bonds decently. Here, they cold form a sheet metal when testing out body parts.

[@daves3893]

@@samuelmendoza9356 For prototyping you can cut a Ureol model and hand for those part in a quarter of the time it takes for that process to make one panel. It is the same technology Ford was showing as the future a few years ago. Also our 3D printers now print inspection fixtures and small press tools overnight.
Its a very long way from being useful. The speed of press tool manufacture is out pacing this for prototypes. We can produce press tools in days, press and laser finish multiple panels for pre and interim production along with scanning and cutting tools cheaply for spares. This just looks great to a room full of students, a company not far from us has gone down with one of these machines and they could not sell it as a process just the robots for re-assigning to something else. It may have been useful when it started with lots of hand made panels with sheet metal workers but the world has moved on and companies are much more flexible and dynamic now with process.

for one off protype and for old cars where the parts are no longer in production

[@krusher74]

sounding so clever but you cant ever read the video description . it “will use this technology to consider the commercialisation of after-service parts and repair parts for older cars.”

[@nexpro6985]

Incredibly expensive production method. Probably only suitable for prototypes and one-offs.
In the time it takes to produce two panels by this method a pair of press dies could be machined.

[@michaelbuttle7772]

But how much would the press tools cost. Much more cost effective to produce by this method for small quantities, once they know its right/works etc them make press tools for production runs
