Multi-objective Optimization of Forming Quality in Single Point Incremental Forming via Response Surface Methodology
摘要
Abstract
The poor forming quality is still one of the biggest challenge for the development and commercialization of single point incremental forming,the forming quality include surface quality and geometric error.In this paper,the cone shape is taken as the research object,Box-Behnken design for cone parts forming have been performed,where four factors and three levels were considered as the experiment scheme.The effects of the four input parameters (tool diameter,step down,sheet thickness and wall angle) on the two outputs including surface roughness and geometric error had been investigated,each of them are predicted by using quadratic equations,then the independent and simultaneous optimization has been used for the present models.It can be concluded that the step down presented the most significant liner effects on surface roughness,while sheet thickness to geometric error.With the target of minimal synchronization of surface roughness and geometric error,which are 0.97 μm,1.939 mm,four processing parameters were optimized with tool diameter as 16 mm,step down as 0.5 mm,sheet thickness as 0.57 mm and wall angle as 65° respectively,under such circumstances.关键词
