Abstract The present study focuses on the effects of cutting speed, feed rate and cutting tool material on the machining performance of carbon graphite material. Polycrystalline Diamond (PCD) cutting tools are used in machining experiments and its performance is compared with the tungsten carbide (WC) and Cubic Boron Nitride (CBN) tools. Machining performance criteria such as flank and nose wear and resulting surface topography and roughness of machined parts were studied. This study illustrates that feed rate and cutting tool material play a dominant role in the progressive wear of the cutting tool. The highest feed rate and cutting speed profoundly reduce the tool wear progression. The surface roughness and topography of specimens are remarkably influenced from the tool wear. Major differences are found in the wear mechanisms of PCD and WC and CBN cutting tools.

切削参数和刀具对碳石墨材料加工性能的影响

摘要 目前的研究重点是切削速度、进给量和刀具材料对碳石墨材料加工性能的影响。多晶金刚石 (PCD) 刀具用于加工实验，并将其性能与碳化钨 (WC) 和立方氮化硼 (CBN) 刀具进行比较。研究了加工性能标准，例如侧面和刀尖磨损以及加工零件的最终表面形貌和粗糙度。这项研究表明，进给率和刀具材料在刀具的渐进磨损中起主导作用。最高的进给率和切削速度极大地减少了刀具磨损进程。试样的表面粗糙度和形貌受刀具磨损的显着影响。
