摘要: 应用统计学中的响应面方法,以背吃刀量,主轴转速,进给量和切削宽度为设计变量,切削力为响应,建立切削力的二阶数学模型。以45钢铣削试验为例搭建硬件测试系统。将响应面方法融入到LabVIEW8.6编程之中,设计软件系统。该系统功能丰富,输入影响因子的个数,给定因子的取值范围,就能自动生成中心组合设计试验方案,并对试验数据进行采集、计算和分析,得到切削力响应面模型。

Abstract: With back cutting depth,spindle speed,feeding and cutting width as design variables,and cutting force as response,a second-order mathematical model of cutting force is built using the response surface method of statistics.The hardware test system of cutting experiment for 45 steel is built.The response surface method is incorporated in LabVIEW 8.6 programming to design the software system.By inputting the number of impact factor and the factor value scope,the software system can automatically generate a center combination experimental design scheme and it can collect,calculate and analyze the experimental data,and,finally build the response surface model.
