Abstract
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.
