摘要
针对精密镗床运动轴制动延时大,存在紧急情况下极易发生大型整体钛合金结构件与机床碰撞的安全隐患,解决了PLC控制器总线通信、控制逻辑优化和PLC编程等问题,修复了已停产的原控制系统漏洞,提高了精密镗床加工过程的安全性和可靠性,满足了航空大型整体结构镗孔时的加工需求。
The movement axis of the precision boring machine has a large braking delay,and there is a potential safety hazard that large-scale integral titanium alloy structural parts collide with the machine tool in emergency situations.This article solves the problems of PLC controller bus communication,control logic optimization and PLC programming,repairs the loopholes in the original control system that has been discontinued,improves the safety and reliability of the precision boring machine processing process,and the processing requirements for boring large-scale aviation structures have been met.
