高速逆向车削细长轴

本文对加工细长轴正向切削和逆向切削时的受力和变形进行了分析，建立了在切削力作用下发生弯曲变形的力学模型，并对机床——工件——刀具组成的工艺系统进行综合优化组合，得出高速逆向切削细长轴可以提高轴的刚性，减少其弯曲变形，保证轴的加工精度的结论。

Using Resection in High Speed Turning the Long and Thin Axle

The stress and the distortion have been analyzed when the long and thin axle is being cut and reversely cut in this article. Mechanical model has been established under the cutting force function. The craft system which is composed of the machine tool, work piece and cutting tool has been optimized. A conclusion that it is possible to enhance the rigidity , reduce the bending strain, and guarantee processing precision has been arrived at, when the thin major axis is cut reversely with high speed.
