在给定的公差下，根据刀位点轨迹的程序段分割误差确定程序段的大小，剔除多余的型值点，保证加工指令的长度不超出CNC系统提供给用户的内存空间。

This method make use of given error to control the section length and to removal superfluous type value points. The method can reduce working code length to a minimum without overgauge.

用于比较测量高精度长度尺寸和形位公差，也可作为高精度测量仪器的指示表。

To measure pinpoint accuracy dimensions and shape; position errors by comparative method , also can be used as indicators of pinpoint measuring apparatus.
