摘要
分析了用工业个人计算机研制ＣＮＣ的优越性，提出了以ＩＰＣ－２８６为基础构成ＣＮＣ系统的具体方案，阐明了系统在ＤＯＳ环境下并行处理的实现以及对ＤＯＳ不可重入问题的解决方法．
The advantages of developing a CNC system using the Industrial Personal Computer (IPC) are analyzed and a practical scheme is proposed. A master-slave distributed system is worked out using an IPC-286 and a self-made motion control card. The real-time multi-task concurrent processing in DOS environment is described. The master employs the process switchover to accomplish data processing and display processing in turn, while the slave adopts the timing interruption to tackle interpolation and position control. The master and the slave are coordinated through the same timing interruption. The method for solving the non-reentry of DOS in the system is explained.
