Abstract
Abstract In a machine having a frame and a moveable table mounted on the frame, the moveable table having a plurality of workpiece carrying stations that are moveable to serially locate each station adjacent a tool mounted on a crosslide on the frame for operation on the workpiece at the station. The machine is provided with variable positioning means for limiting movement of the tool a predetermined distance relative to each of the workpieces at the operating station. The variable positioning means includes a reference device mounted on the crosslide and in fixed location relative to the tool, and a movement limiting device for each of the workpiece stations and adapted to be engaged by the reference device at the end of the tool operation. The limiting devices are equal in number to the number of workpiece stations and each may be dimensioned in accordance with the workpiece mounted at the station. Thus, variances in tolerance stackup and movement in the machine itself will be accommodated for each workpiece station and the workpiece mounted thereon. Means are provided to move the limiting devices into adjacent relation to the reference device as the machine table is moved to place a different station adjacent the crossslide. Further means are provided to prevent retrograde movement of the limiting devices as they are moved from station to station.
