Abstract

A numerically controlled machine tool can simultaneously perform a variety of machining operations using work on a first main shaft and work on a second main shaft. A first tool post is movable together with a second main shaft in the direction of a main shaft axis and in a direction orthogonal thereto in a plane, while a second tool post is movable at least in the same biaxial direction as the directions of movement of the first tool post. A control device superposes the movement required for the first tool post to machine work on the movement required for the second tool post to machine work, so that the machining operation of the work by the tool on the first tool post and the machining operation of the work by the tool on the second tool post are simultaneously performed.
