Abstract
A machine tool capable of performing screw-machining on a rotating workpiece has a tool rest which can attachably and detachably equip a turning tool with an insert on its tip and is provided so as to be freely driven to move in first and second axial directions orthogonal to each other. The tool rest is also being provided so as to freely rotate about a third axis orthogonal to the first and second axial directions so as to be positioned at a selected tool-rest angle with respect to the workpiece. The machine tool includes suitable features to allow inputting of machining information, computing of a cutting pattern, and execution of screw-machining.
