CNC Cutting Process Optimization for the Surface Quality of the EPS Based on SPSS Software

采用二元正交回归试验设计方法和信噪比试验分析法,对密度为18 kg/m3消失模材料的数控切削表面质量进行研究,确定主轴转速、轴向进给量、切削宽度及进给速度对数控切削消失模表面质量的影响比重。在多因素共作用的情况下,结合SPSS软件的图像处理功能,具体分析单因素对数控切削消失模表面质量的影响情况,并提出各因素最优切削参数。运用SPSS软件的数据处理功能得出数控切削表面质量二元表达式,为消失模数控切削加工提供依据。

The CNC cutting surface of 18 kg/m3-EPS material was studied based on the dualistic orthogonal regression experimen-tal design and the analysis method of signal-to-noise ratio test. The different effect proportions of the spindle speed,axial feed,cutting width and radial feed speed on the cutting surface quality of EPS were determined. Under the joint action of the other factors,the im-pact of one factor on the cutting surface quality of EPS was analyzed in detail by integrating the image processing function of the SPSS software,and the optimal cutting parameters for each factor were found out. The dualistic expression for the CNC cutting surface was obtained by using the data handling function of SPSS software,which offering reference for EPC CNC cutting machining.
