Summary of Single Point Diamond Turning Technology for Hard, Brittle and ferrous Metal Materials

Single point diamond turning technology is one of the important manufacturing processes for optical components with nano characteristic surface. This processing technology has been widely used in the fields of space science, biomedical engineering, military, national defense and optics. However, diamond tools are limited in cutting hard, brittle and ferrous metal materials. For instance, the tool wear is intensified, the tool life is shortened, and the machining quality of the workpiece surface is reduced, and so forth. In order to reduce tool wear and improve the machining quality of workpiece surface, relevant scholars have proposed different solutions. This study will sort out the relevant research on single point diamond turning technology for improving the machining quality of hard, brittle and ferrous metal materials from the aspects of single point diamond turning auxiliary process, workpiece modification, tool performance improvement and superhard materials and tools, It is proposed that in the future, many kinds of energy field assisted single point diamond turning technology and diamond tool technology based on focused ion beam modification will be the focus of research.
