摘要
针对国内数控打字系统效率低、无法识别国外主流钢构软件支持的dstv文件格式等缺点,研究基于网络数控的思想,突破高速转塔最优路径换刀、钢构软件数据格式自动识别等关键技术。介绍了采用独立型可编程控制器(PLC)对数控转塔钢构打字系统的伺服刀塔进行控制,针对数控转塔机床的特殊结构,以三菱FX2N系列PLC控制伺服电动机进行分度,可双向回转和任意刀位就近换刀,位置闭环控制,以软件的方式实现刀塔与刀具库之间最优路径换刀。介绍了PLC与网络计算机数控系统(NCNC)、刀塔电动伺服系统及机床本体执行部件相互间的分布式信息传递方式,以及如何有机协调这几者之间的关系,以达到良好的逻辑控制效果。
Aiming at the low efficiency of inland CNC typing system and the shortcoming of unidentifying the foreign mainstream steel structure software support＇dstv＇,based on network CNC,break high-speed turret optimal path changing tool,this paper researches on steel structure software data format automatic identification key technologies,mainly introduces the external PLC which controls the servo turret cutter of CNC turret typing system.For special machine structure of CNC turret,it uses Mitsubishi FX series PLC to control servo motor index,the two-way and arbitrary position near change tool,and the position closed-loop control and uses the software to realize the tower and the tool library changing cutters in optimal path.At the same time it also introduces the distributed information transfer mode among PLC,NCNC,tower electrical servo system and machine parts,and how to coordinate the relation to achieve good logic control results.
