对淬硬钢车削过程的机理和白层形成机理进行了初步研究。进行了圆柱车削和端面试验，以研究切削过程的各个方面，包括产生的切屑、刀具刀片及其磨损状况、产生的表面，以及切削力和比切削能量的变化。通过称量切屑并测量其长度获得的切屑横截面积在大多数情况下小于切割横截面积。

A preliminary investigation was undertaken to study the mechanics of the turning process for hardened steels and the mechanism of white-layer formation. Cylindrical turning and facing experiments were conducted to investigate various aspects of the cutting process including the chips generated, the tool inserts and their wear condition, the surfaces produced, and variations in the cutting forces and specific cutting energy. Chip cross sectional areas, obtained by weighing chips and measuring their lengths, were found to be smaller than the cutting cross-sectional areas in most cases.
