Recommendation of a Measure for Enhancing the Precision of Dimensions of Foil Products in Single Point Incremental Forming Technology

Abstract:

Single Point Incremental Forming (SPIF) has become a popular technology of forming sheet materials in the recent decades. However, the springback phenomenon, an inborn property of almost all elasto-plastic materials, reduces the precision of dimensions of the products by the finished forming session. This paper attempts to find out a measure to minimize this unwanted obstacle by using both empirical and simulating methods in order to define the relations of springback values among the forming parameters such as diameter of the forming tool, its revolution per minute, its velocity and its feed rate. Analyzing these equations to extract the appropriate parameters of forming for enhancing the precision of SPIF products is the final aim of this paper.
