Numerical control system

A numerical control method, and a numerical control device for subjecting a workpiece to a predetermined machining operation on the basis of a machining program. When a specified signal is generated during a machining operation under the control of the machining program, a subprogram, to which the numerical control device responds to execute processing in accordance with the specified signal, is stored in memory beforehand. Machining in progress under the control of the machining program is interrupted temporarily by the generation of the specified signal. At the same time, the subprogram is read from memory and is utilized in the processing of predetermined process steps. Following such processing, machining under the control of the machining program is resumed from the point of interruption or from an earlier point.

Method of numerical control and device therefor

Numerical control machine tool

Numerical controller equipped with optional block skip function

Position error correction equipment

A numerical control system for executing numerical control processing on the basis of a command program, and for actuating a machine in accordance with the results of the processing steps to machine a workpiece in the manner specified by the instructions in the command program. There are prepared a plurality of system variables, the values of which represent a variety of operational conditions of the machine or of a numerical control device. A user macro, having at least an identification and an instruction that employs the system variables, is stored beforehand in a memory. The command program is programmed to include a user macro call instruction. A prescribed user macro is read out from the memory by means of the user macro call instruction, thereby to allow processing in accordance with the user macro. For example, it is possible to execute processing upon reading out input/output interface signals, clock time and a variety of machine positions.
