本文讨论了52100淬硬至58-62 HRC钢的车削试验结果。选择一组五种不同的切削条件，在每种刀具的使用寿命内加工五种多晶硅立方氮化硼（PCBN）刀具。其目的是确定切削参数对刀具磨损、刀具几何形状变化和最终工件表面质量的影响。

This paper discusses experimental results of turning experiments on 52100 steel hardened to 58-62 HRC. A set of five different cutting conditions was selected to machine with five polycrystalline cubic boron nitride (PCBN) cutting tools for the life of each tool. The objective was to determine the effect of the cutting parameters on tool wear, changes in tool geometry, and resultant workpiece surface quality.
