介绍单点金刚石切削理论模型并得出其在一定刃口钝圆半径下的最小切削厚度公式；对金刚石刀具几何角度、切削参数、机床性能、加工环境、材料特性、气源波动等影响单点金刚石车削加工质量的因素进行分析，并提出一定的解决措施，为单点金刚石车削加工提供一些参考。%Introduce the mechanism of micro cutting and the minimum cutting thickness. The paper point out that the precision of ultra-precision machine, cutting tool, process environment, quality of material and the professional level of the worker would make a difference on the component and the solving scheme is also put forward. This paper provides a reference to the SPDT.
