Design project 1967/8: report of control systems committee

Abstract

Starting from the initial concept of a small Numerically Controlled lathe, a measurement and actuation system has been developed. An 'absolute" fluidic control system with rotary and linear encoders has been chosen and designed. Hydraulic actuation for spindle and axis drives has been chosen, the spindle having a hydrostatic drive system involving no mechanical gearing. An estimation has been made of the cost of the system
