小型数控雕刻机控制系统设计

小型数控雕刻机采用常见的开环数控系统。开环数控系统通常由步进电动机控制,其原理是通过数控装置发出进给脉冲,经功率放大后,驱动步进电动机转动1个步距角,再经减速齿轮带动丝杠旋转,并通过丝杠和螺母副传动,使工作台产生相应的位移。开环控制系统的精度较低,速度也较低;但是其结构简单,易于调试,目前在简易型、经济型数控系统中采用。数控雕刻机在机械加工工业上有着重要的地位,其相关性研究已成为国内外的热点。

Design of Control System of Small CNC Engraving Machine

Small CNC engraving machine uses a common open-loop numerical control system. CNC system generally uses open loop stepper motor, the control principle is that numeral equipment sent each feed pulse, the power is amplified to drive a stepper motor rotates one step angle, and then the reduction gear drives screw rotation, and through screw and nut transmission, a corresponding displacement of the table is accomplished. Accuracy of open-loop control system is low, the speed is relatively low, but it is simple in structure, and easy to debug, it has been wildly used in economical numeral con- trol system. CNC engraving machine in the machining industry has an important position, and its correlation study abroad has become a hot spot.
