Simulation of Engine Block Drilling
Machining simulation can quick supply valuable data to help improving machine processing quality and efficiency. And it is playing an important part in the development of modern machining theory. In this paper, the drilling process of an engine block was simulated in the software of DEFORM-3D. The geometry models of cutter and workpiece were simplified to avoid too low efficiency of simulation running. The mesh weight factors were specified to keep geometry models from changing too much from the real situation. 11 simulation experiments were carried out. And through regression analysis of the result data, the drilling load formulas were obtained to predict the axial force and moment in the drilling process of engine block.
