船用柴油机关键零部件数控加工工艺参数优化及仿真研究

Study on NC Machining Process Parameters Optimization and Simulation for the Key Parts of Marine Diesel Engine

针对我国船用柴油机企业在生产制造过程中工艺参数选择过于保守的问题,在分析国内外工艺参数优化、工艺仿真的基础上,提出一种数控加工工艺参数优化及仿真验证的思路:建立工艺参数优化数学模型,通过求解计算获得优化后的工艺参数,并对优化的工艺参数进行仿真验证,直到获得最优的工艺参数。并以船用柴油机缸盖零件的数控加工工艺参数优化及仿真为例,验证了此思路的可行性。

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 parame？ters 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.
