摘　　要：基于Box-Behnken Design(BBD)响应面法设计试验,选取切削速度、进给量和背吃刀量作为优化变量,以切削力、表面粗糙度和加工时间作为响应指标,通过Design-Expert软件分析研究各优化变量间的交互联系。结果表明,最优参数组合为切削速度110m/min,进给量0.13mm/r,背吃刀量0.5mm;对应的切削力为165.95N,表面粗糙度为0.918μm,加工时间为5.44s;研究结果对基于数控车削工艺技术的参数优化有一定的参考价值。Based on the Box-Behnken Design(BBD)method of response surface method,this paper designs the test,selects cutting speed,feed rate and back draft as the optimization variables,and takes cutting force,surface roughness and machining time as the response indicators.Through the analysis of design expert software,the interaction between the optimization variables is studied.The results show that the optimal parameter combinations are as follows,cutting speed is 110m/min,feed rate is 0.13mm/r,and feed depth is 0.5mm.The corresponding cutting force is 165.95N,surface roughness is 0.918μm and processing time is 5.44s.It can be seen that the research on parameter optimization based on NC turning technology has a certain reference value.
