PURPOSE:To obtain a parallel processing NC (nemerical controller) which has small waiting time by using the 2nd processor which is started by the 1st processor to select and execute a preprocessing program and transferring the result of said execution to a work area of a real processing program. CONSTITUTION:A parallel processing NC contains a computer 1, a main program 2 for real processing and a parallel processing controller 3. The controller 3 receives an instruction (a) from the computer 1 and executes selectively the parallel processing programs 5 and 8 for operation. Then a selected parallel processing program 5, for example, is executed, and the result of an operation E3 is supplied to a work area 7 of the program 2. The controller 3 stops its working after confirming a parallel processing end instruction (b) of the program 5. In addition, the real processing K3 is executed by means of said operation E3 when the real processing K2 executed in parallel to the operation E3 is through. |
