摘　　要：给出了系统的功能描述、结构组成以及各主要模块的设计分析。针对由于国外技术封锁造成的激光切割机数据输出问题,提出了一个基于屏幕截取和数字识别技术的数据双向传递方案并给出了具体的实现方法。从而在同一台数控激光切割机(Prim a LW-1530)上实现了工件检测、测量造型和数控加工等功能。该方案可用于基于W indows的各类数控系统来拓展数控设备的使用范围。This paper gave the function description, structure and main module design of the system. Faced with a laser cutting machine＇ s data output problems caused by foreign technological embargo on China, it presented a bidirectional data transfer program based on the screen capture and numerical recognition technology and its concrete method. Thus work-piece delection, measurement shaping and NC machining in the same CNC laser cutting machine （Prima LW-1530） was accomplished. The program can be used in various NC system based on Windows to extend the use of NC machines.
