Abstract: A lathe system includes a spindle capable of gripping a bar and moving back and forth in an axial direction of the bar and a tool post to which a first tool is attached. The lathe system can manufacture a plurality of products having an identical shape from the bar by repeating a machining of the bar, a cutting off of a machined portion of the bar, and a grip change by the spindle, the grip change by the spindle comprising releasing the bar, moving back, and re-gripping the bar at a predetermined gripping position. The lathe system further includes a gripping position selecting unit capable of selecting a special gripping position at which the spindle re-grips the bar when a state of the machine tool system meets a predetermined condition, the special gripping position being different from the predetermined gripping position.

Abstract: A machine tool capable of facilitating the setting of the vibration cutting conditions. A control unit acquires a feed speed of a object to be fed without a vibration (Fa), a number of rotations of a spindle required for a single cycle of the vibration (K), and a returning amount (R) representing a distance of a returning feed per the single cycle of the vibration. According to the acquired parameters, the control unit decides at least one parameter among a cutting amount (D) representing a distance of a change in a position of the object per the single cycle of the vibration, a cutting feed speed (F) of the object, and a returning feed speed (B) of the object. The control unit controls the position of the object to be fed with the vibration at least according to the decided parameter.
