本文研究了用CBN刀具加工或硬化轴承钢的端面车削工艺。对比能量、产生的切屑、刀具镶块和机加工表面进行了研究。研究发现，比切削能量与最大未变形切屑厚度直接相关，这归因于沿啮合切削刃犁削。产生的大多数芯片是锯齿形的，这可以解释相对较大的芯片面积比。

An investigation is reported of the face turning process for machining or hardened bearing steel using CBN cutting tools. Studies were made of the specific energy, the chips generated, the tool inserts, and the machined surfaces. The specific cutting energy was found to be directly related to the maximum undeformed chip thickness, which is attributed to plowing along the engaged cutting edge. Most of the chips generated were saw-toothed, which can account for the relatively large chip area ratios.
