高速铣削天然大理石切削特性研究∗

摘要

To provide the research of surface integrity of marble material with adequate basis,and make the high speed milling parameters of marble material optimized. this experiment mill the marble specimen under different cutting parameters,analyze the cutting mechanism of marble material, obsever proces-sed marble specimen surface morphology by SEM,and analyze the influence of processing parameter change on the sur-face quality. Founding that with the increase of spindle speed, the processing surface quality was enhanced unceasingly, but with the increase of cutting depth, the marble processing surface quality was becoming low.%为了给大理石材料表面完整性研究提供充分的依据，使大理石材料高速铣削加工参数得到优化。该实验在不同的切削参数下对大理石试件进行铣削加工，分析了大理石材料的切削机理，采用扫描电镜观察加工后大理石试件表面形貌，分析了加工参数的变化对表面质量的影响。发现随着主轴转速的提高，加工表面质量不断提高，但切削深度的增加，使大理石加工表面质量降低。
