According to the complexity of the lathe cutting process, based on consideration of the constraint condition of machining process, cutting parameter optimization mathematical model is established with three objectives, which are productivity, tool loss of life and surface roughness. Derivation and analysis, finding that the objective function and constraint condition analysis and cutting parameters are about, cutting speed , quantity equation and inequality of feed speed anddepth of cut. Using the improved multi-objective cat swarm optimization to optimization, the results show that the proposed algorithm can effectively solve cutting parameters optimization problem.
