Abstract
A control device for a numerically controlled machine tool includes both on/off and continuously variable switches which are coupled via a computer to associated machine functions such as coolant flow or feed rate. The computer is programmed to operate in any one of three modes. In the first mode the manually controlled input switches are read by the computer during computer-controlled processing of a first workpiece according to processing information stored in memory, the computer stores information regarding the state of the switches for later use, and also controls the machine functions to correspond with the current state of the input switches. In the second mode the computer controls the machine functions during computer-controlled processing of subsequent workpieces in accordance with previously stored information, independently of the current position of the input switches. In the third mode, the computer controls the associated machine functions during computer-controlled processing of a workpiece in accordance with the current state of the input switches, without storing this information. In use, this control device allows an operator to program associated machine tool fu…
