To provide a method to carry out complicated surface machining such as graining or the like without decreasing machining accuracy and machining efficiency. In a machine tool including a main spindle head capable of relatively moving in three perpendicular directions with respect to a workpiece and an additional spindle being provided at the main spindle head and capable of moving in a Z spindle direction, while the main spindle head relatively moves with respect to a working surface S of the workpiece along a smoothly curved surface R which is smoothed so as to be restricted within the movement distance in the moving direction of the additional spindle, the additional spindle moves by a difference between the working surface S and the smoothly curved surface R, and makes a tool T to machine the working surface S.
A machining control method for a machine tool, that comprises a main spindle head capable of relative movement in three perpendicular directions with respect to a workpiece, an additional spindle provided at the main spindle head and capable of moving itself in a specified direction, moving with the relative movement of the main spindle head so as to relatively move with respect to the workpiece, and a tool provided at the additional spindle so as to machine the workpiece, said method comprising:
