摘　　要：数控车削加工中,对刀高度误差不但对零件的尺寸精度有影响,对零件的形状精度也有影响。通过计算分析,得出对刀高度误差越大,对零件尺寸影响越大。在高度误差一定时,零件的尺寸越接近于对刀尺寸,其对零件的尺寸影响越小,提出了提高零件加工精度的具体措施。In NC tuming, tool sitting error affects the size and the shape precision of workpiece. Through calculation and analysis, it cames to conclusion that the greater of tool sitting error is, the greater influence on the size precision is, In fixed tool sitting error, when the size of workpiece is more close to the size of tool sitting, the influence on the size precision is smaller. The concrete meas- ures are put forward for improving the processing precision.
