Simulation and parameter optimization of the key working procedure of engine box

The engine box and the bearing cover have high concentricity requirements. In response to this, cutting parameter optimization of the main bearing bore boring process is presented. Combined with the processing requirements and processing characteristics of the main bearing bore boring process, the three-dimensional finite element model was established based on the Deform-3D. The variation of cutting force, cutting temperature and cutting deformation of two materials are obtained by changing the cutting parameters in cutting simulation. Through the comparison, the impacts of processing precision due to different materials are analyzed. On this basis, a cutting parameters optimization program of boring main bearing bore is proposed.
