| Research Abstract |
The machining of grinding wheel is an important research problem related to grinding finishing process. In this study, the turning experiment was performed on white alumina grinding wheels, Hose size is 100mm in diameter and 40mm in length, by the use of cemented carbide, sintered CBN, and sintered diamond single point cutting tools, The cutting speed ranged from 30 to 150m/min, the maximum depth of cut was 1.0mm, and the feed was 0.2 to 0.8mm/rev. Thus, the tool wear and cutting force were measured for various cutting conditions, and the optimum operating condition was obtained. The effects of speed, feed, rake angle, and approach angle were specially investigated. The cutting mechanism was also studied by means of a low speed orthogonal cutting experiment, FFT analysis, and static shear and compression tests. It is evident from this study that grinding wheel can be cut easily by using a proper cutting tool, such as K01, CBN, or diamond, and by selecting relatively low cutting speeds, large negative rake angle, and large tool tip radius.
