Abstract

Information of a machine control means to be selected for each system is inputted through a manual input unit and then stored in a storage unit for storing a selection state of the machine control means through a machine control means selecting unit. A machine control means execution unit executes the machine control means for each control system independently according to the selection state stored in the storage unit.

Claims

1. A multi-system numerical control device having a plurality of control systems, comprising;

a machine control means storage unit for storing information of a plurality of machine control means;

a selecting unit for selecting said machine control means for each of said plurality of control systems;

a selection state storage unit for storing a selection state of the machine control means selected for each control system by said selecting unit; and

an execution unit for executing the machine control means for each control system independently according to the selection state stored in said selection state storage unit.

2. The multi-system numerical control device according to claim 1, wherein each of said control systems includes a program analysis unit for analyzing a program specified by said execution unit and an execution means.

3. The multi-system numerical control device according to claim 1, wherein it further comprises a manual input unit, and information of the machine control means is inputted through the manual input unit and then stored in said machine control means storage unit through said selecting unit.

4. The multi-system numerical control device according to claim 1, wherein said machine control means is a program for attaining a turning function.

5. The multi-system numerical control device according to claim 1, wherein said machine control means is a program for attaining a milling function.
