| 摘 要： | 为解决目前数控机床使用G代码所带来的诸多问题,提出了建立STEP-NC数控系统的方案.整个方案分为控制软件和硬件两部分.控制软件采用模块化设计,分为译码模块、人机接口、任务协调器、轴组和轴模块.译码模块针对STEP-NC加工程序面向对象的特点,将加工特征规划为加工单元路径集合.其他模块根据单元路径以有限状态机为行为模型,最终控制伺服系统实现加工.硬件部分采用开放式体系结构和不同厂商的产品,通过串行实时通讯系统总线连接到一起.经过加工试验,实现了规定的加工特征,证明译码模块工作正确,数控系统稳定可靠.

| Abstract: | To overcome shortcomings aroused by G code in Numerical Control(NC) machine tools,a scheme for establishing STandard for the Exchange of Product model data-NC(STEP-NC) system was proposed.The scheme was divided into two parts: control software and hardware.Control software with modularized design included five parts:interpreting module,man-machine interface,task coordinator,axis group and axis module.Aiming at the object-oriented characteristics of STEP-NC program,layout of the manufacturing features was pl... |
