摘　　要：通过PCD刀具切削天然大理石的试验研究,分析了在不同加工参数条件下对PCD刀具切削性能的影响以及刀具的磨损机理。试验结果表明:PCD刀具在加工过程中的磨损机理主要表现为磨粒的磨损、剥落,聚晶层的破损与结合剂破坏等;刀具主轴转速为12 000 r/min、进给速度为1 000 mm/min、切削深度为0.5 mm时,刀具的磨损量最小;且磨损量随刀具主轴转速的增加而降低,随刀具的进给速度和切削深度的增加而增加。The effect of different parameters on cutting performance of PCD tool when cutting natural marble is analyzed.The results show that,the wear form of the PCD tool during the cutting process mainly include the abrasive wear,the breakage of the polycrystalline layer and the damage of the binding agent,etc.Results show that the minimum wear of the tool can be reached at spindle speed 12 000 r/min,feed speed 1 000 mm/min,and cutting depth 0.5 mm.The wear of the tool decreases with the increase of the spindle speed of the tool,and increases with the increase of feed rate of the tool and the cutting depth.
