| Summary: | 碩士 === 國防大學理工學院 === 機械工程碩士班 === 98 === The short life cycle of industrial products leads to development of precision machining. Multi-blade combination grinding tools are
commonly used in machining .The abrasives of grinding tool are not regularly oriented. The knowledge of different performance in
different oriented abrasives is helpful to analyze the diamond grinding tools. This study proposed the analysis of cutting characteristics of diamond tool produced with single crystal diamond in point, line and surface directions and also discussed the morphology, surface roughness and material removal rate in cutting aluminum sample with the simulation of finite element analysis in point direction of diamond tool. The material removal rate is estimated by the induced stress and strain at the workpiece surface to achieve the assisted actual experimental results. According to experimental results, the width and depth after cutting is better when the penetrating depth of diamond tool is 70 μm in point, line and surface directions. The point direction can obtain the good surface roughness. The line direction can obtain the good cutting morphology. Thus, cutting method which is appropriate to three directions of diamond tool is proposed by the observation of cutting characteristics of metals and morphology after cutting.
