摘　　要： 采用低压水射流辅助聚晶金刚石刀具车削花岗岩，采集不同切削条件下切削力的数据，分析了在水射流辅助下刀具进给量、切削深度、切削速度、水射流压力、喷射距离对切削力的影响。结果表明，在实验压力范围内，切削过程中，水射流使岩石受到冲蚀，并使微裂纹扩展，有利于岩石的切削。切削力随着水射流压力的增大而减少。 Granite is turned in lathe using PDC cutter assisted by low-pressure water jet and thecutting force at different cutting conditions is acquired. The influences of cutter feed, cutdepth, cutting speed, water pressure and jet distance on cutting force are analysed. Thisstudy Shows that in the experimental water pressure vange,Water jets rush into granite andmake the cracks develope in granite. In this case, water jet make the granite easy to be cut bycutter. The cutting force reduce with the increase of water pressure.
