Experimental investigation and Optimization of incremental sheet Metal forming process using multipoint Tool and single point tool on aisi 430 202 And 420 stainless steel

Abstract

Incremental sheet metal forming process is considered as one of the flexible way of converting the raw materials into the final product in forming industries. This process is significant in producing a small batch of products. Different shape of products can be manufactured at a minimum cost. Hence this process can neglect the usage of dedicated die for producing a product. Incremental Sheet metal Forming (ISF) is the process, which has wide applications in producing homemade appliances and producing automobile products. These industries have to produce a complex-shaped product with better formability and minimal surface roughness. Usage of the single point tool in the ISF process still faces many problems in meeting the requirements of the customer with respect to formability, surface roughness and also producing the product in minimum duration. The spring back is also the main problem to produce a product with better accuracy. These drawbacks are taken as a main key factor in this research work, and also tried to reduce with a new type of multi-point forming tool which contains more number of balls. newlineStainless steel is used in this work due to its various applications in food industries, automotive, heavy industries, architecture and construction. The study on stainless steel using ISF process is less, even though it has more advantageous properties with respect to industrial applications. In this research work, SS430, SS202 and SS420 are used as test specimens. The newly designed multi-pointed tool is tested on the stainless steel and the outputs are compared with outputs of sheet metal formed with the single-point tool. The outputs obtained using both the tools are wall angle, formability, surface roughness, spring back and forming time. newline
