采用人造金刚石刀具进行精密、超精密切削实验，实验结果表明，在精密切削时影响工件表面粗糙度的主要因素是机床精度、刀具材料和进给量，并取得了人造多晶金刚石刀具可以进行超精密切削的突破性结果。
The experiments of precision and ultra-precision cutting with synthetic diamond tools show that the main factors influencing the surface roughness of the workpiece during precision cutting are the precision of the machine tool, the material of the tool and the feed rate, and the artificial polycrystalline diamond tool can be super-precision Breakthrough results of precision cutting.
