说明：  借助激光测距技术、数控技术和计算机技术，将锥体零件的若干典型截面数字化，根据相关形位公差的定 义，利用计算机进行数据处理，求出被测零件的截面圆度、最大最小直径、垂直度等。
( Using laser ranging technology, numerical control technology and computer technology, will taper parts some typical digital, according to relevant section of the geometrical tolerance stand Righteousness, use computer data processing, to work out the section tested parts roundness, the maximum minimum diameter, vertical degree, etc.)
