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.
