Optimization of Critical Parameters of EDD Steel in Die Cavity Manufacturing

Incremental sheet forming (ISF) process is identified as a potential and economically viable process for sheet metal forming for the low volume production. The process is to prove a very flexible and can be carried out on a computer numerical control (CNC) milling machine, robots, or on machines which are specially designed for ISF applications. In present work, the effort has been made to investigate the behavior of Extra Deep Drawing (EDD) steel in ISF process. The state of stresses and strains in incremental forming of VWACF and VWAPF parts have been studied through finite element simulations. The thickness distribution of these parts has been measured experimentally and compared with the results of finite element simulations (FES) using Ansys software. The changes in microstructure and microhardness are being detected due to incremental deformations which have also been studied through optical microscopic analysis and micro-Vickers hardness tester. It has been again verified by performing the experiments.
