新型数控雕刻机运动控制系统设计

摘要

In the traditional NC engraving machines the machining objects are limited due to the closed inner core. In the novel control system, NC Embedded PC type open architecture was employed to combine PC's excellent massive computing ability with motion controller's real-time control ability. The host computer used dynamic linking library of VC motion controller to realize human-machine interactive such as process of intelligent control and CAD/CAM integration. The lower computer was used to realize the three-axis servo, high speed electrical spindle control and hardware intelligent safety protection with the excellent real-time control ability of GE-400-SV. This control system provides an effective way to promote the system integration and flexible manufacturing ability in engraving industry.%为解决传统雕刻机数控内核封闭而导致加工对象受局限的问题,将新型数控雕刻机运动控制系统采用NC嵌入PC型开放式构架,把PC机的海量运算能力与运动控制器实时控制能力有效结合起来.上位机PC利用VC调用运动控制器的动态链接库函数实现了加工过程智能化控制、CAD/CAM集成等人机交互功能,下位机利用GE-400-SV运动控制器的强大的实时控制能力实现了雕刻机的三轴联动伺服、高速电主轴控制以及硬件层智能安全保护.该控制系统为提升数控雕刻机的系统集成化程度和柔性加工能力提供了一条有效解决途径.
