Design and Realization of Control circuits of the micro milling machine and the safety inspection function of its spindle

摘要

Based on the analyses of the current research status of PC + NC type control system in micro-machining technical field both at home and abroad, an "IPC + PMAC motion controller" type open CNC system is established. Control circuits of the micro milling machine control system are designed, which include the realization of the functions of spindle status display, feeding tables status display, IPC status display, machine tool alarm, interlocking control of the function buttons and the corresponding indicator light control of spindle cooling, spindle lubrication, spindle alarm and spindle running status. Finally, the safety inspection function of the spindle is achieved through writing corresponding PLC programs. The research of this paper can provide reference for the study of the micro milling machine control system.
