PCD刀具超精切削表面质量的研究

Study on Ultraprecision Machining Surface Quality Using PCD Cutting Tool

用人造聚晶金刚石 (PCD)和天然单晶金刚石 (SPD)刀具对无氧铜材料进行了切削试验 ,对加工表面质量进行了检测和分析。结果表明 :两种刀具在超精切削中获得的加工表面质量具有相似性 ,因此PCD刀具在一定程度上可替代SPD刀具进行超精切削加工。

The experiment of cutting oxygen free copper using PCD and SPD cutting tools are carried out, and the surface quality of machined workpieces is tested and analyzed. The result shows that during the process of ultraprecision cutting, the similar workpiece surface quality is acquired by the two types of cutting tools.Therefore, to some extent, SPD cutting tools can be replaced by PCD cutting tools.
