Abstract

A numerical control device stops automatic operation after machining of a specific part without the need to manually modify a machining program or to perform macro computation. The numerical control device includes a program analysis section that, upon executing a command program for continuously machining a plurality of parts, analyzes the command program, an analyzed program execution unit that executes the command program analyzed, a program stop condition setting section that sets a program stop condition in the command program based on a machining stop condition specified by a user, a program stop determining section that determines whether an execution block of the command program satisfies the program stop condition based on an analysis result, and a program stop requesting section that, when it is determined that the execution block satisfies the program stop condition, outputs an execution block stop request to the analyzed program execution unit.

Claims5

Dependent claims

A numerical control device that operates in accordance with a command program, comprising:

a program analysis section that, upon executing a command program for continuously machining a plurality of parts, analyzes the command program;
an analyzed program execution unit that executes the command program analyzed by the program analysis section;
a program stop condition setting section that sets a program stop condition in the command program on a basis of a machining stop condition for stopping the continuous machining specified by a user;
a program stop determining section that determines whether an execution block of the command program satisfies the program stop condition on a basis of an analysis result of the command program by the program analysis section;
and
a program stop requesting section that, in a case in which the program stop determining section determines that the execution block of the command program satisfies the program stop condition, outputs an execution block stop request of the command program to the analyzed program execution unit.
