A Study of Effect of Tool Wear on Surface Quality in Fast Tool Servo Machining

摘要

Sharp diamond tool with small tool nose radius is usually used in Fast Tool Servo (FTS) machining and it is easily susceptible to wear. This paper presents an investigation of tool wear of the single crystal diamond tool and its effect on surface generation in ultra-precision machining with FTS. A cutting experiment has been conducted with sharp and worn diamond tools and the surface quality of the machined surfaces are measured and compared. The results show that the form accuracy of the machined workpiece is adversely affected by the tool wear of the diamond tool. The results of the study provide a better understanding of the performance of diamond tools in FTS machining.
