摘　　要：本文应用压电式铣削测力仪试验研究含铝高速钢铣刀铣削Cr12材料的铣削力.研究了主轴转速、进给速度、轴向切深和径向切深对最大铣削力的影响,用正交实验法和多元线性回归分析方法建立了铣削力数学模型.试验结果表明,X、Y方向最大铣削力随进给速度、轴向切深、径向切深的增加呈现上升趋势,而随着主轴转速的增加有减小趋势.Cr12 was taken as the milling material and we have tested milling force with piezoelectric dynamometer.We have also researched the spindle speed,feed rate,axial depth of cut and the radial depth of cut on the impact of the maximum milling force of and have established the model of the maximum milling force by Orthogonal experimental design and multiple linear regression analysis method.The results show that the maximum milling force of the Cr12 materials has an increasing trend with the feed rate,axial depth of cut and radial depth of cut being increased.However,the spindle speed on the impact of the maximum milling force has opposite trend.
