Abstract
A turret (24) is clamped on a tool rest body (22) by a pair of coupling elements (66, 68). During a rotational indexing operation for a tool selection, the tool rest body (22) and the turret (24) are moved relative to each other along a Z-axis, to disengage the coupling elements (66, 68) and thus unclamp the turret (24). At this time, the tool rest body (22) is moved relative to a lathe base (10) along the Z-axis, synchronously to the relative movement of the tool rest body (22) and the turret (24) along the Z-axis. The direction and distance of the motion of the tool rest body (22) relative to the lathe base (10) is adjusted so as to eliminate the relative movement between the turret (24) and a spindle stock (12). This motional control serves to prevent the turret (24) and a tool attached thereto from moving relative to the spindle stock (12) and a workpiece, whereby the problem of interference between these components can be solved.
