Abstract :-Incremental sheet forming is an advanced and efficient technique for performing forming operations when complex forming shapes or mass production for formed products is taken into consideration. ISF is widespread due to its flexibility in experiments and economically it is much more preferable. Unlike traditional forming methods tool in ISF is controlled numerically by CNC machines and therefore is preferred by great many industries for its applications in forming. For example, light weight alloys are used hugely in automobile industry, so it needs fast and cost efficient process to design and manufacture complex shapes like door frames and bumpers with great geometrical accuracy and good surface quality. This work presents various researches regarding experiments performed in ISF with different areas of focus such as tool geometry, sheet metal thickness, surface finish, sheet material etc. Tool geometry plays a vital role in ISF process when it comes to unusual and complex shapes and hence more and more optimization is in dire need for today’s researchers. Therefore, this literature review would offer a clear idea as to how much success is achieved in ISF and how much work is yet to be done regarding optimization of tool geometries in Incremental Sheet Forming process.
