摘要

Edge chipping and tool life are two of the most serious issues during machining process of brittle materials. Ultrasonic vibration cutting is considered relatively low cutting force and high machining efficiency for machining hard and brittle materials. To find an effective method considering the effect of grit size of diamond coated grinding head, tool geometry and tool path to reduce edge chipping and increase tool life using ultrasonic-vibration-assisted grinding in drilling and enlarging hole process of sapphire glass is studied in this paper. There are three aspect to study the strategy of controlling edge chipping in this paper: (a) The designed experiments reveal the effects on cutting force, edge chipping and tool life with different tool geometry design (taper angle and chip groove ) in hole drilling process. The result shows that edge chipping can be reduced effectively by optimizing the taper angle and chip groove of tool design. (b) The relationship between grit size and edge chipping is revealed by investigating the microscope view of cutting behavior and several experiments are designed and conducted. (c) The tool path affects on tool life in hole enlarging process is investigated. To increase tool life and obtain smaller edge chipping thickness, a tool path strategy is obtained in this research: 3D spiral tool path method. With 3D spiral tool path method in hole enlarging process, tool wear will be much more well-distributed compare to traditional concentric circles tool path, so better tool life will be obtained.
