Abstract

A numerical control system for machine tools uses a secondary memory store in which repeated blocks of data can be temporarily stored and are available on calls using punched tape instructions. The punched tape output together with that of the secondary memory is processed in the arithmetic unit before being transferred to the machine interpolator to generate control signals for the drive system. A priority control unit directs the arithmetic unit in relation to interrupt signals. If a particular component profile involves repeated passes of the machine tool cutter with only the depth of cut varied, when the procedure avoids the need to repeate the data block on the tape.
