Through analyzing and accounting evocable error of tool's transmutation during milling process, the compensatory method to the error in NC machining has been put forward.
通过分析计算数控铣削过程中刀具变形引起的误差，提出对这种误差的补偿方法。

Finally, the origin of range error and compensatory methods are pointed out.
最后指出了系统测距误差的来源及补偿措施。
3
The in-process measurement principle for the spindle rotation error is presented and the roundness and cylindricity on-line measurement and compensatory control system is developed.
