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 addition, according to various states of the establishment, proceeding and cancel of the cutting tool noseradius compensation, the data are stored in different way.
In the spherical surface NC turning, the correct tool length compensation and tool noseradius compensation are significant to guarantee the precision of spherical surface.
