PROBLEM TO BE SOLVED: To provide a numerical control device that is comparatively low in operating frequency and can also be restrained in heat emission and power consumption, uses a multi-core processor less expensive than a multi-CPU configuration and is provided with means for dividing the unit of shaft control processing into any number of shafts and causing the control to be decentralized into the multiple cores of the multi-core processor.SOLUTION: A numerical control device that controls a machine configured of multiple shafts and equipped with a multi-core processor having multiple cores comprises execution start request means that requests execution of shaft-by-shaft processing of multiply divided shafts into which the shaft control processing of the multiple shafts is divided by units each of a prescribed number of shafts, divided shaft-by-shaft processing execution means that executes the shaft-by-shaft processing of multiply divided shafts in response to the request from the execution start request means, and execution completion monitoring means that monitors the state of completion of the divided shaft-by-shaft processing by the divided shaft-by-shaft processing execution means.SELECTED DRAWING: Figure 4 【課題】比較的動作周波数が低く発熱や消費電力も低く抑えられ、かつマルチＣＰＵ構成よりも安価なマルチコアプロセッサを使用し、軸制御処理を任意の軸数単位に分割し、マルチコアプロセッサの複数のコアに分散させて実行させるための手段を備えた数値制御装置を提供すること。【解決手段】複数軸で構成される機械を制御し、複数のコアを有するマルチコアプロセッサを備えた数値制御装置において、前記複数軸の前記軸制御処理を所定の軸数単位で複数に分割した複数の分割軸別処理を、前記複数のコアにそれぞれ実行させることを要求する実行開始要求手段と、前記複数のコアにそれぞれ配置され、前記実行開始要求手段による要求を受けて、前記分割軸別処理を実行する分割軸別処理実行手段と、前記分割軸別処理実行手段による前記複数の分割軸別処理の完了状態を監視する実行完了監視手段とを備える数値制御装置を提供する。【選択図】図４
