| 摘 要： | 使用TiAIN涂层整体圆柱立铣刀,对P20淬硬钢(41HRC,32HRC)进行了高速铣削试验,考察了各种切削速度下的切屑变形,微观硬度、切削温度和切削力.切削参数包括:切削速度151～942 m/min,每齿进给量0.1 mm/齿,轴向切削深度1.0 mm.切削宽度1.0 mm.结果表明:两种硬度的P20钢都产生了锯齿形切屑,切削温度随切削速度的增加而增大,工件硬度、切削速度对切屑变形和切削力有重要的影响.

| Abstract: | Using solid carbide cylindrical milling cutter with TiAlN coating,P20 steels(heat treated to 41HRC and 32HRC) were machined at a high milling speed.The morphology of the chips,chip microhardness,chipping temperature,and the milling forces at various speeds are investigated.The cutting parameters involved are: cutting speeds in the range of 151 m/min to 942 m/min,feed of 0.1 mm/tooth,axial cutting depth of 1.0 mm,and radial width of 1.0 mm.The results show that saw-tooth chips are formed during high speed mi... |
