论述了无尺寸标注的复杂图形用描图方式直接输入计算机的数控线切割自动编程技术。只要将需编程的图形在数字化仪上描绘一遍，就能将图形信息直接输入到计算机中，通过软件立即转化为线切割３Ｂ程序或ＩＳＯ代码。
This paper discusses the automatic programming technology of NC wire cutting which is input directly into the computer without drawing the complex graphics with dimension drawing. As long as the graphics to be programmed are plotted on the digitizer, the graphics information can be input directly into the computer and immediately converted to a Wire-Cut 3B program or ISO code by the software.
