A combined tool and work changer assembly is disclosed for a machine tool wherein a carrier moves in a first path on an elongated beam parallel to the length of the machine tool. Both the tool changer and workpiece are mounted on the carrier and the tool changer is movable in the space defined by X, Y, and Z mutually perpendicular axes, with the first path being parallel to the Z-axis. This first path has a length sufficient to move the tool changer between a tool storage magazine and the machine tool, and the work changer is mounted on the second portion of the carrier to be movable in this first path between a workpiece storage area and the machine tool. Numerical control is used to control movement of the tool changer and movement of the workpiece changer with common control of both changers along the first path by movement of the carrier. This simplifies the construction of the combined changers. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Tool and work changer assembly

A diameter gage is disclosed which measures a plurality of diameters on a workpiece after the workpiece has been machined. First and second U-shaped gage frames mount first and second gage blocks relative to a gage platform, and this gage platform is moved vertically upwardly to a position whereat the gage blocks of each set straddle different ones of the plurality of different diameters on the workpiece. Parallel leaf springs provide low friction mounting of the gage blocks, and also provide urging means to urge the gage blocks into contact with the opposite sides of the workpiece. An electrical output gage is moved in accordance with the relative movement between the two gage blocks of each set to provide an error signal which is passed to the numerical control to correct the machining diameter of the machine tool which machines successive workpieces.
