A control method of a machine tool includes the steps of: determining a raised height, and determining a maneuvering height; causing the tool to move horizontally to a machining position; causing the tool to move vertically to a machining height to machine the workpiece; causing the tool to move vertically to the raised height, and when the tool is at the maneuvering height, causing the tool to move horizontally to a next machining position while the tool is moving vertically; causing the tool to move vertically to the maneuvering height while the tool is moving horizontally to the next machining position; and causing the tool to move vertically to the machining height to machine the workpiece.
