Abstract

Abstract One or more processors (11a to 11c) for controlling machining stations having one or more shafts are arranged. The number of processors depends upon the constitution of the machine tool, and these processors are connected via first common bus (31) to a CRT and MDI unit (21), NC machining program supply means (22, 24), and programmable controller (23) that controls power sequence of the machine. These units are commonly used by the processors. Further, the processors (11a to 11c) are connected to shaft control units (41 a to 41 c) via a second common bus (51) so that each of the processors can exclusively use a predetermined shaft control unit through which the corresponding machining station is controlled.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 154 words
A numerical control apparatus which has a display unit, a manual data input unit, NC machining program supply means and a programmable controller for controlling a magnetics sequence of a machine, and which is for numerically controlling a machining station composed of one or more axes via an axis controller, characterized by comprising: processors, of which one or more are provided in conformity with a machine tool arrangement, for numerically controlling respective ones of one or a plurality of machining stations; a first common bus connecting the processors and connecting the display unit, manual data input unit, NC machining program supply means and programmable controller; axis controllers, of which one or more are provided in conformity with the machine tool arrangement, for driving the machining stations by commands from respective ones of the processors; and a second common bus connecting the processors and connecting one or more axis controllers used exclusively by the processors.
Claim 2
Dependent Claim 154 words
A numerical control apparatus which has a display unit, a manual data input unit, NC machining program supply means and a programmable controller for controlling a magnetics sequence of a machine, and which is for numerically controlling a machining station composed of one or more axes via an axis controller, characterized by comprising: processors, of which one or more are provided in conformity with a machine tool arrangement, for numerically controlling respective ones of one or a plurality of machining stations; a first common bus connecting the processors and connecting the display unit, manual data input unit, NC machining program supply means and programmable controller; axis controllers, of which one or more are provided in conformity with the machine tool arrangement, for driving the machining stations by commands from respective ones of the processors; and a second common bus connecting the processors and connecting one or more axis controllers used exclusively by the processors.
Claim 3
Dependent Claim 38 words
A numerically control apparatus according to claim 1, characterized in that one processor among said processors is provided with a bus control function for allowing the first and second common buses to be dedicated to a predetermined processor.
Claim 4
Dependent Claim 37 words
A numerically control apparatus according to claim l, characterized in that the manual data input unit is provided with a function for specifying a correlation between a processor and the axis controller used exclusively by said processor.
