Stepping Motor - Hydraulic Motor Servo Drives for an NC Milling Machine

PBU Achi


In this paper the retrofit design of the control system of an NC milling machine with a stepping motor and stepping motor - actuated hydraulic motor servo mechanism on the machines X-axis is described. The servo designed in the course of this study was tested practically and shown to be linear - the velocity following errors being proportional to the axis feedrates. This property makes the servo system suitable for future on-line control from a microcomputer.
