PROBLEM TO BE SOLVED: To provide a numerical control device capable of suppressing backlash occurring during tool tip point control.SOLUTION: A numerical control device has a tool tip point control function controlling movement of a control point of a tool on the basis of a movement instruction of a tip point of the tool in a multi-axis processing machine. The numerical control device determines whether movement of the control point of the tool based on the movement instruction of the control point of the tool is ended at a predetermined number of interpolation cycles, and as a result of determination, when it is determined that the movement of the control point of the tool based on the movement instruction of the control point of the tool is ended at the predetermined number of interpolation cycles, outputs a movement instruction in which a movement route of the control point of the tool is directly interpolated.SELECTED DRAWING: Figure 11 |
