超精密切削氟化钙单晶金刚石刀具磨损研究
Research on Diamond Tool Wear in Ultra-precision Cutting of CaF2 Crystals
摘要
Abstract
In order to study the diamond tool wear and its effects on the cutting process in ultra-precision cutting of CaF2,the long distance cutting experiments of CaF2 crystals were carried out.The effects of cutting distance on the micrograph of tool damage were observed systematically,the tool damage mechanism was analyzed,the relation between tool damage and cutting model was discussed through analyzing the influences of tool damage on the micrograph of machined surface and cutting force.The research findings show that： the tool damage model in ultra-precision cutting of CaF2 crystals are grooving damage and notch breakage,the development of the tool damage followed with cutting distance is that the tool damage is extended from the grooving damage in flank face to notch breakage in rake face,and the cutting mode is also changed from the ductile mode cutting to brittle mode cutting.The research results supply the technological support for nano-scale ductile mode cutting of large-size CaF2 crystals.关键词
