Programmable feed control apparatus for a machine tool

摘要

A programmable feed control apparatus for controlling the feed movement of a machine member in response to control data of a feed control program stored in a program memory is disclosed wherein the programmable feed control apparatus includes a flip flop which is set by completion of the generation of a set of timing pulses in order to perform a feed movement of the machine member. The flip flop is reset when the feed movement is completed in order to generate another set of timing pulses to read out the control data.
