Abstract
Incremental Sheet Forming (ISF) is a relatively new sheet metal forming process. It hasshown great diversity in its applications ranging from automotive to biomedical fields. However, the geometries having steep walls cannot bemanufactured in single stage incremental forming process due to the fact that the maximum wall angle that can be formed is limitedfor a given sheet material and thickness. This limitation can be overcome with Multi Stage Incremental Forming (MSIF) process. This paper presents some of the experimental studies in multi stage incremental forming of steel sheets to get steep wall angles.The effect of process parameters in forming cylindrical, square and spherical cups in MSIF process has been discussed.
