Nissan Eyes 'New Life' for Discontinued Models with Latest Technology
Japanese carmaker Nissan might give a new breath of life to its discontinued models as it has "taught" robots to make car parts out of sheet steel.
This breakthrough technology is targeted to make replacement parts for discontinued models more widely available for customers.
Known as dual-sided dieless forming, the program, which Nissan hopes to be commercialized, involves two synchronized robots working from opposite sides of a steel sheet, using diamond-coated tools to gradually shape the steel.
Thanks to its flexible production, short lead times, and minimal upfront costs, the new technique could make it commercially viable to produce and sell a wide variety of after-service and replacement parts in small volumes for cars that Nissan no longer makes.
This was previously not possible due to the high upfront costs and long lead times to develop and make dies for stamped parts.
Until now, dual-sided dieless forming had been considered too difficult to commercialize.
- The development of advanced programs capable of controlling both robots with a high degree of dimensional accuracy, enabling the formation of detailed convex and concave shapes;
- The application of a mirrored diamond coating to tools, reducing friction while eliminating the need for lubrication. This has numerous benefits, including consistency of surface quality and low-cost, environmentally- friendly operation; and
- The generation of optimized pathfinding logic for robots, drawing on the ample expertise and press-forming simulation techniques ordinarily used by Nissan's production engineering teams. This enabled Nissan to achieve high quality results early in the development process.
Nissan plans to continue pursuing advancements in mass production while also dedicating R&D resources to honing its flexible low-volume production techniques.
