To provide a combined lathe machine equipped with automatic tool replacing means which can simultaneously inhibit the effect of deflection amount generated by empty weight of a work, the effect of pitching generated by the variation of deflection amount in vertical deflection in which a bed has lower rigidity, and the effect of thermal displacement caused by motor and bearing for turning rotary tool unit, and its control method.
In the combined lathe machine, the turning tool attached to a tool working spindle 25 controls movement of a carriage 23 in the direction containing Y-axis directional component so as to move around the horizontal direction Yt perpendicular to Z axis, then performs turning work of the machining workpiece W mounted on working spindle of the work.
