PROBLEM TO BE SOLVED: To provide a numerical control device capable of controlling a cutting path so as to keep a cutting amount constant even when a tool inclines in a vertical direction (X axis direction) with respect to the rotational axis of a workpiece in skiving processing.SOLUTION: A numerical control device for carrying out skiving processing control includes a tool data storage part for storing tool data created based on the inclination or the shape of a tool, a processing program analysis part for reading and analyzing a command block from a processing program to generate and output command data indicating the command path of the tool, an interpolation part for executing interpolation processing based on the command data to generate and output interpolation data for each interpolation period, and a correction part for generating, when the command block is a block for instructing skiving processing, correction data for correcting the command path based on the tool data stored in the tool storage part, and outputting the correction data along with the interpolation data output from the interpolation part.SELECTED DRAWING: Figure 4 【課題】スカイビング加工において、ワークの回転軸に対し垂直方向（Ｘ軸方向）への工具の傾きがある場合であっても、切り込み量が一定になるように切削経路を制御することが可能な数値制御装置を提供すること。【解決手段】本発明の、スカイビング加工制御を行う数値制御装置は、工具の傾きや形状に基づいて作成された工具データを記憶する工具データ記憶部と、加工プログラムから指令ブロックを読み出して解析し、工具の指令経路を示す指令データを生成して出力する加工プログラム解析部と、指令データに基づいて補間処理を実行し、補間周期毎の補間データを生成して出力する補間部と、指令ブロックがスカイビング加工を指令するブロックである場合、工具データ記憶部に記憶された工具データに基づいて指令経路を補正する補正データを生成し、補間部が出力する補間データに合わせて補正データを出力する補正部と、を備える。【選択図】図４
