Abstract

In a numerically controlled machine tool which has a linear feed axis and a rotational feed axis and in which a main spindle and a table are movable relative to each other, a position error and an attitude error produced by an operation of a linear feed axis and a rotational feed axis are measured at a plurality of measurement points set within a movable range of the linear feed axis and the rotational feed axis, and the position error and the attitude error thus measured are stored as an error map in correspondence to a position of the linear feed axis and a rotation angle of the rotational feed axis.
