目前,PC数控系统的体系结构主要有以下几种形式: (1) 专用数控加PC前端的复合式结构这类系统的设计思想是将通用PC和专用NC通过高速信息交换通道连接到一起组成一复合式数控系统。这类系统的优点是可以保持原有数控基础,发挥厂家在以硬件专用芯片实现特殊控制功能等方面的优势,且技术上容易保密,因此多为一些老的数控厂
At present, the system structure of PC numerical control system mainly has the following forms: (1) The specialized structure of NC plus PC front-end composite structure The design idea of this kind of system is to connect the general-purpose PC and specialized NC through the high-speed information exchange channel to form a Compound CNC system. The advantage of such systems is that they can maintain the original CNC basis, give full play to manufacturers in the hardware-specific chips to achieve special control functions and other advantages, and technically easy to keep secrets, so mostly for some old CNC plant
