摘　　要：在高速加工中心上,用直径2mm的小直径铣刀,采用单因素法,在相同材料切除率的情况下对45淬硬钢(硬度为HRC52)进行了圆弧路径和直线路径的高速铣削对比实验。通过对切削力信号的分析研究,找出了铣削参数对铣削力的影响规律,获得了等切除率条件下直线路径切削力均大于圆弧路径切削力的结论,建立了该实验条件下的切削力经验公式。On a high--speed machining center, arc and straight line path constrast experiments were completed by milling 45 hardened steel （HRC52） with Ф2mm micro--end mill and using single factor method. The aim was to find out the influence laws of cutting parameters on the milling force by analyzing the cutting force signals. The result is that the cutting force is much bigger in straight line path than that in arc path, then a cutting force empiricial formulas under experimental conditions was obtained.
