摘　　要：以振动法和声发射技术为基础,采用超精密金刚石车削加工技术对H62黄铜模具材料进行大直径菲涅尔透镜模具加工工艺的实验研究。实验表明:刀尖角、刀具后角和切削液是影响加工表面质量的主要因素。当刀尖角54°、刀具后角3°、切削液采用微乳化液时,切削状态最佳,可以有效地提高刀具耐用度和加工表面质量。In this paper,based on the vibration and acoustic emission technology,the ultra- precision diamond turning processing technology was adopted for processing experiment research of large diameter Fresnel lens mold of H62 brass die materials. The experiments show that: tool angle,tool clearance angle and cutting fluid are the main factors to affect the surface quality. With tool angle 54°,tool clearance angle 3°and cutting fluid using micro emulsion,cutting condition is the best,tool life and surface processing quality can be improved effectively.
