Abstract

1,215,170. Programmed control of machine tools. INTERNATIONAL BUSINESS MACHINES CORP. Nov.6, 1968 [Dec.21, 1967], No.52478/68. Heading G3N. A control system for a plurality of machine tools comprises means for reading out command words form a data store and controlling a decoder system in response to a second portion of a word, indicating the machine tool, to emit a pulse to enable a gating circuit directing a first portion of the word, indicating numerical control information, to the machine tool. As shown, a central processing unit CPU has a memory M storing, for each machine controlled, a plurality, of command words appearing at every address which is a multiple of the number of machines. The unit CPU executes a read out of a command word, in response to a pulse from a synchronizing signal generator ES, into a selector circuit SEL by which it is distributed, through gating circuits, not shown, according to the machine number and with the exception of the machine number bits into a command decoder CD.1-5. The command decoder decodes each two bits of axis control information and converts them into an energizing signal for a driving amplifier DR for a servomotor of the machine tool MT.1-5. Additional bits control functions, such as operations of a cutter shaft or supply of cooling oil, through an auxiliary function control circuit AUX.
