Abstract
A numerical control unit is provided that can change an override value according to various workpiece materials and can extend the tool life. A numerical control unit includes a variation storage unit that stores a variation in override value of a feed speed or a spindle speed for each workpiece material, an override value setting unit that sets the override value based on the variation in override value according to the material of a workpiece being machined; and a control unit that changes the feed speed or the spindle speed based on the override value.
