Abstract:Considering the deficiency in conservative process parameter selection in the manufacturing process of marine diesel engine enterprises, based on the research of process parameters optimization and process simulation, a kind of NC machining process parameters optimization and simulation thought was carried out. First, process parameter optimization mathematical model was set up, the optimized process parameters were obtained by solving calculation, and simulation was carried out until the optimal process parameters were obtained. Finally, the NC machining process parameters optimization and simulation of marine diesel engine cylinder head part was taken as an example to verify the feasibility of the approach.
