<p>PURPOSE:To make numerical control workings of shapes different in attitude or size possible by adding conversion parameters to a subprogram call instruction shapes to be worked which are different from the shape of a subprogram in attitude or size. CONSTITUTION:Plural subprograms are stored in a subprogram memory 101, and a main program including the subprogram call instruction is recorded on an NC tape 102. A processor 104 reads out NC data from the NC tape 102 block by block in accordance with a control program stored in an ROM105 and stores it in a data memory 107. If NC data is the subprogram call instruction, conversion parameters stored in the data memory 107 are inserted to the main program. Thus, the numerical control working of a shape, which is subjected to coordinate conversion by the indication of conversion parameters, is possible.</p> |
