PROBLEM TO BE SOLVED: To provide a numerical control device having a function of preventing interference between a tool and a work while keeping a cycle time short for a positioning command moving a plurality of axes simultaneously.SOLUTION: A numerical control device according to the present invention is configured to control, according to program commands, a machine which processes a work by moving a tool and the work relatively by driving a plurality of axes, and comprises a command analysis part 10 which analyzes the program commands to generate movement command data, and a path correction part 11 which generates a correction path curving away from the work for a linear path from a current position of the tool to a command position commanded with movement command data when a command by a program command is a positioning command, thereby controlling the axes based upon the correction path.SELECTED DRAWING: Figure 4 【課題】複数の軸を同時に移動させる位置決め指令においてサイクルタイムを短く保ちながら工具とワークとの干渉を防止する機能を備えた数値制御装置を提供すること。【解決手段】本発明の数値制御装置は、複数の軸を駆動して工具とワークとを相対移動させることによりワークを加工する機械をプログラム指令に基づいて制御する数値制御装置であって、プログラム指令を解析して移動指令データを生成する指令解析部１０と、プログラム指令による指令が位置決め指令である場合、工具の現在位置から移動指令データにより指令される指令位置への直線経路に対してワークから離れる方向へ湾曲する補正経路を生成する経路補正部１１と、を備え、該補正経路に基づいて前記軸を制御する。【選択図】図４
