System for numerically controlling a machine tool

DETAILED DESCRIPTION It is the main object of the invention to realize a numerical control of a machine tool of the direct numerical control (DNC) system with an electronic computer of the general use type in the form of the entirely automatic operation commander, on the basis of the idea of using an electronic computer for the entirely automatic operation commander which is common to a plurality of numerical control circuits for machine tools.
In accordance with the present invention there is provided a system for controlling numerically a machine tool having at least a numerical control circuit including a manual data panel, characterized in that: said system comprises a plurality of machine tools, a plurality of numerical control circuits, each of which includes a manual data inputting panel, an entirely automatic operation commander device which is provided commonly for said plurality of numerical control circuits, and transmission means between each of said numerical control circuits and said operation commander device for exchanging input data for said machine tool and output data from said machine tool, for exchanging data for said manual data panel and data from said manual data panel and for exchanging treatment program data; whereby the entire processes of said plurality of machine tools are controlled by said operation commander device.
