<p>PURPOSE:To reduce influence exerted on a control operation due to shortage of the capacity of a memory, by sending directly a subprogram registered in an internal memory of a host computer, to a numerical control device instead of a subprogram call command by subprogram developing means. CONSTITUTION:A working program which has gone into an internal memory 4 of a host computer 1 is read out by a CPU 2 and sent to a subprogram developing means 3. When a subprogram call command exists in the working program which has been sent, the subprogram developing means 3 reads out the subprogram corresponding to the subprogram call command from a subprogram memory 5, couples a subprogram body instead of the subprogram call command of a main program, and sets it is as a program having no subprogram call command. Thereafter, the main program which has coupled the subprogram is sent to a program analyzing means 8 of a numerical control device 7 by a coupling means 6, and the data which has been analyzed by the main program is sent to a machine control means 9. In this state, by the machine control means 9, a machine tool is controlled.</p> |
