摘要
针对航空发动机微孔冷加工所需的超快激光数控机床设计了一种基于工控机的控制系统。文章采用工控机作为整个激光数控机床的主控制设备,将控制软件运行于工控机上。控制软件与工控机、数控系统、协同控制单元等组成控制系统,控制系统的主要控制任务包括:初始化激光器和复合光束扫描模块、向数控系统传送光束指向调整电机的位置信息、配置协同控制单元完成恒重叠螺旋扫描和非圆形面扫描控制等。控制系统还包含简单的工艺数据库同时实现对工艺数据库的增、删、改、查以及维护,并为整个激光数控机床提供简单易操作的人机交互交界面。整个系统最终能达到机床的控制要求,满足加工需求。
A control system based on industrial computer is designed for the ultra fast laser numerical control machine tool,which is needed for the aircraft engine micro hole machining. In this paper,industrial control computer is used as the main control device of the whole laser numerical control machine tool and the control software running on the computer. The whole control system consists of control software,industrial control,numerical control system,the coordinated control unit,etc. Its main tasks include: initialize the laser and composite beam scanning module,transfer the position information of the motor to the numerical control system,configuring cooperative control unit to complete the constant overlapping spiral scanning and non circular surface scanning control,etc. The control system contains a simple process database,which can achieve the process database's CRUD( create,read,update,delete) operations and database maintenance,and it also provides an easy to operate man-machine interactive interface for the laser numerical control machine tool.Eventually the whole system can meet machine control requirements and the demand of processing.
