摘　　要：采用自制的金刚石复合片研磨成PDC刀片,研究了不同形状的PDC刀片在切削含硅20%的硅铝合金时的表面粗糙度,并研究了不同切削速度下的表面粗糙度和切削温度。随着切削速度提高切削温度也提高,切削速度达到1000m/min左右,温度超过400℃,已加工工件表面粗糙度迅速降低。结合文献数据分析,认为高速切削硅铝合金时,已加工工件表面粗糙度主要受控于切削温度。Grinding the PDC cutting tools with self-made polycrystalline diamond compact, then cutting the silicon aluminum alloys that content 20silicon with different shape PDC cutting tools. Effects of cutting parameters on surface roughness and cutting tem- perature was researched. Experiments show that the cutting temperature increase with the cutting speed, the cutting temperature exceeds 400 when the cutting speed reaches 1000m/min, and the surface roughness decreases quickly. Analysis showed that the surface roughness is mainly controlled by results and the results of literature. the cutting temperature with the experimental
