【Abstract】 Dry hard machining is an environmentally clean cutting process, advanced cutting tool materials such as PCBN has become the key to enable the dry hard machining technology, an alternative to costly abrasive-based process. Process parameters and cutting mechanism in dry hard cutting are completely different from those in conventional machining, based on these concepts, the workpiece material, cutting tool material, cutting mechanism of hardened steels with chamfer tools, surface integrity, concepts of minimum quantity cutting fluid application are reviewed in this paper and it is expected that the paper will speed the applications of dry hard machining in China.更多还原
