摘要

摘要: 金刚石切削加工光学玻璃时,工件表面粗糙度与刀具磨损直接相关,为研究切削距离递增下的金刚石刀具磨损及其对工件加工表面粗糙度的影响,进行了Soda-lime玻璃金刚石切削的刀具磨损试验,并对刀具磨损形貌、后刀面磨损带的材料成份、工件的表面形貌及粗糙度进行了检测.结果表明:切削距离递增下的金刚石刀具前刀面磨损表现为平滑且均匀的月牙洼磨损,后刀面磨损表现为磨损带逐渐增大,且磨损带内有沿切削方向的微沟槽产生;切削距离未达到150 m时,工件表面粗糙度R_q、R_a及R_max值始终低于32、25及300 nm,切削距离超过150 m后,工件表面粗糙度显著增大.机械摩擦作用、热化学作用及磨料磨损作用为导致金刚石刀具磨损的主要原因.

Abstract: The surface roughness of workpiece was directly related to the tool wear in diamond cutting of optical glass. To investigate diamond cutting tool wear and its influence on the surface roughness, experiments of diamond turning with cutting distance were carried out on soda-lime glass in this work. The wear morphology of diamond tool and the material composition of flank wear area were detected, and then the corresponding surface features of soda-lime workpiece and the surface roughness were determined. Experimental results indicate that the wear on rake face was characterized by the smooth and uniform crater. The wear land on flank face extended with the increase of cutting distance and became rough gradually by micro-grooves along the cutting direction. Surface roughness, i.e. R_q, R_a and R_max of workpiece at a cutting distance of 150 m, was lower than 32, 25 and 300 nm, respectively. Once the cutting distance exceeded 150 m, the surface roughness of the workpiece increased rapidly. The main mechanisms inducing tool wear in diamond cutting of glass were mechanical wear, thermo-chemical wear and abrasive wear.
