Simulation of Stainless Steel Drilling Mechanism Based on Deform-3D
An emulation study of the drilling mechanism by general purpose twist drills is conducted by using FEM analysis software Deform-3D. Application of finite element software Deform-3D, some characteristic parameters of the work piece and the cutting tool material are combined. The load boundary conditions and the friction between tool rake face and chip are analyzed and defined. The chip separation criteria are chosen. The finite element analysis simulation of pretreatments is completed. By the finite element simulation analysis, the three-dimensional FEM model of twist drill is build. The scraps forming process and the distributed situation of cutting force，cutting temperature in the drilling process are analyzed. The effect of cutting variables on drilling forces of stainless steel is analyzed. The drilling temperature and the drill wear condition are discussed. The effect of the main geometric parameters on the stainless steel twist drill drilling performance is studied.
