Numerical control device

Abstract

A numerical control device inputs a machining program to control an operation of a machine tool and outputs feedback data obtained as a result of the operation of the machine tool. The numerical control device includes a machining-program analysis unit that analyzes the machining program having a machining shape command to which a mark or a specific program command is attached and that outputs a marking instruction; a delay unit that delays the marking instruction until the feedback data indicating a result of an operation of the machine tool based on the machining shape command is obtained; and a feedback-data output unit that, when having detected the feedback data and the delayed marking instruction, executes, onto the feedback data, marking corresponding to the mark or the specific program command attached to the machining shape command and outputs the feedback data.
