This article introduces tool noseradius compensation in CNC lathe process, and analyses how to compensate when CNC lathe possesses TNRC function or does not.
In the spherical surface NC turning, the correct tool length compensation and tool noseradius compensation are significant to guarantee the precision of spherical surface.
在球面的数控车削加工过程中，刀具长度补偿和刀尖半径补偿的正确与否对于保证球面的轮廓精度极为重要。
