进入八十年代,国外数控自动编程软件已进入了“面向工艺”的发展阶段,这类软件除了几何计算外,还具有较强的工艺处理能力,甚至直接用于CNC系统中实现“在线编程”。因而使用方便、编程效率高。而国内目前的编程软件尚处于由“面向几何”向“面向工艺”的过渡阶段;投人生产使用 Into the eighties, foreign CNC automatic programming software has entered a “process-oriented” stage of development, in addition to these types of software geometry calculation, but also has a strong process capability, and even directly used in CNC system to achieve “online programming” . So easy to use, high programming efficiency. However, the current programming software in China is still in the transition from “geometry-oriented” to “technology-oriented”;
