1·This article introduces tool nose radius compensation in CNC lathe process, and analyses how to compensate when CNC lathe possesses TNRC function or does not.

介绍了数控车床加工中的刀尖半径补偿，对数控车床具备或不具备刀尖半径补偿功能时如何进行补偿进行了分析。

2·In addition, according to various states of the establishment, proceeding and cancel of the cutting tool nose radius compensation, the data are stored in different way.

此外，按照刀补建立、进行及撤消等不同的状态采用不同的方法进行数据的存储，从而提高程序的可扩充性及可替换性。

3·In the spherical surface NC turning, the correct tool length compensation and tool nose radius 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。

4·In the production practice, this problem should be kept in mind and resolved by programming for compensating the variation of tool nose curvature radius and removing the error.

在实际生产中要加以注意，并通过编程以补偿刀尖圆弧半径的变化，消除误差，使问题得以解决。
