我国在CAD／CAM技术方面起步较晚，CAD／CAM系统多数是从国外引进的，包括系统硬件、软件及应用软件，且往往不配套，在应用时，必须对不同进日设备间或软件间的通讯接口进行二次开发，才能使其充分发挥应有的效用。本文所介绍的内容就是根据工厂实际情况所做工作的总结。一、C
China started late in CAD / CAM technology. The majority of CAD / CAM systems are imported from abroad, including system hardware, software and application software, and are often not complete. In application, the CAD / CAM system must be imported between different equipment or software Communication interface for secondary development, in order to make it give full play to its due effectiveness. This article describes the content is based on the actual situation of the factory work done. First, C
