Milling force prediction model for high-speed end milling 3Cr2Mo steel
【摘要】 在五轴高速数控加工中心上,采用多因素正交试验法对3Cr2Mo塑料模具钢进行了高速铣削试验.基于概率统计和回归分析原理,建立了3Cr2Mo的铣削力预测模型,分别对回归方程和回归系数进行了显著性检验,并用实例对预测模型的精度进行了分析.通过正交试验直观图,可以看出铣削参数对铣削力的影响规律.为合理选择铣削参数提供了可靠的依据.
【Abstract】 A predictive model is presented for the cutting forces in high-speed end milling of 3Cr2Mo diemold steel based on multiple-regression analysis.The data for establishing model is derived from experiments conducted on a high-speed machining center according to the principles of DOE(design of experiments) method.The significances of the regression equation and regression coefficients are verified.The effects of milling parameters on milling forces are investigated by analyzing the experimental curves.
