Using two tools movement in incremental forming process by finite element analysis

Abstract

Abstract. Single Point Incremental Forming, SPIF and Two PointIncremental Forming, TPIF are two types of Incremental Sheet Forming ISF processes with high economic potential payoff for rapid prototyping applications. The process requires a CNC machining centre, a spherical tip tool and a simple support to fix the workpiece. The process is more complicated by highly nonlinear boundary conditions, namely contact and frictional effects. However, this process, numerical approach, dominated by the Finite Element Method, FEM is being used. The paper presents the data and main results of a study on the effect of using two forming tool movements through FE analysis. The certain process conditions referring to the test blank, tool, etc., applying ANSYS application program. The results show that the upper TPIF process is more stable during the deformation process steps by chattering statuses evaluation and improve the strain distributions of the deformed blank.
