Abstract

Incremental sheet metal forming is widely used and one of the well-developed manufacturing process these days. In ISF the parts formed have good quality, geometric accuracy, and ready to be used. This is the new technique as in the conventional forming avoiding the use of punches and dies it is not possible to manufacture the parts of good quality and it also leads to higher setup time and the manufacturing cost of the product is also high which is undesirable. To overcome these problems there is a need of process which reduces higher set up cost of punches and dies. In the conventional forming it also takes higher lead time which effects badly the cost and idle time. The ISF process is carried out with the help of a blank holder to hold the work piece and a hemi-spherical tool of different nose radius is utilized. A pre-generated tool path may be developed in CAD/CAM software, need to be integrated with the cnc machining center. To optimize the process parameters in ISF,L9 orthogonal array, taguchi method and ANOVA were developed for various process parameters such as feed rate, spindle speed, tool diameter, step depth[1]. The aim of this study is to optimize the forming time, surface roughness and geometric accuracy. the software MINI TAB-17 has been used for the analysis purpose. Analysis of variance(ANOVA)has been employed to investigate the characteristics and experimental results of the process.
