摘　　要：用CVD涂层刀具精车45钢工件,再采用高端数字化测试系统,对精车成型的45钢工件切屑形态进行比对评价,分析不同工艺参数组合对45钢加工质量的影响规律。结果表明:在切削速度V为395 m·min^(-1)、进给速度Vf 为0.12 mm·r^(-1)、背吃刀量ap为0.5 mm的最佳车削工艺参数下,45钢工件的切屑形态较好,其切屑呈弹簧状排出,实现了CVD涂层高速高精加工45钢的车削效果。The 45 steel workpiece was finish-turned with CVD-coated tools,and then the chip morphology of the finish-turned formed 45 steel workpiece was comparatively evaluated using a high-end digital testing system,including the analysis of the influence law of different combinations of process parameters on the machining quality of 45 steel.According to the results,the chip morphology and surface quality of the 45 steel workpiece were better under the optimal turning process parameters of cutting speed V of 395 m·min^(-1),feed rate Vf of 0.12 mm·r^(-1) and back draft ap of 0.5 mm.The chip discharge was spring-like,which achieved the high speed and high precision turning effect of CVD coating on 45 steel.
