Abstract

Conventionally hydraulic piston - cylinder servos are actuated using analogue controls for machine tool axis drives. In this paper a design of the axis control system of an NC milling machine which employs a small stepping motor to digitally actuated hydraulic piston - cylinder servo drives existing on the machines Y-axis is described. The digital control designed in this study was practically tested and found to be a linear servo, thus making it suitable for economic control from a computer.
