PROBLEM TO BE SOLVED: To provide a numerical control device capable of easily creating a machining program in a machine tool having a table rotating axis, shortening a program length, and easily changing a tool length. SOLUTION: A machining moving path is instructed on a work coordinate system rotating with a table. The moving path instruction of a linear moving axis is interpolated on the basis of the moving speed instruction to acquire the interpolation positional information of the moving path (S5, 6). Further the moving instruction of the rotating moving axis is interpolated to acquire the interpolation positional information of the rotating moving axis (S8). The interpolation positional information of the linear moving axis is corrected on the basis of the interpolation positional information of the rotating moving axis (S9, 10, 11). A servo motor of each corresponding axis is driven on the basis of the corrected interpolation positional information of the moving path and the interpolation positional information of the rotating moving axis. As the work coordinate system is rotated with the table, the rotating work is machined on the basis of the machining shape defined by the work coordinate system. COPYRIGHT: (C)2003,JPO
