    摘要： A method of positioning a grooved grinding wheel relative to a disc-like circular workpiece for edge grinding the workpiece using the groove in the wheel includes the steps of mounting the workpiece for rotation about a first axis, mounting the grinding wheel for rotation about a second parallel axis, effecting relative movement between the workpiece and the wheel to engage the rim of the wheel within the groove and performing a preliminary grind. The position of the wheel is axially adjusted in accordance with the measurements made on the profile of the rim produced by the preliminary grind, and the rim is ground again with a second preliminary grind with the grinding wheel located at the axially shifted position. The steps of grinding and measuring the periphery of the workpiece are repeated until the rim profile possesses the desired accuracy. The final position of the grooved grinding wheel is then utilized for grinding future wafers.

    摘要： A radius dresser for generating a profile having arcuate portions generated about different centers and/or different radii of rotation. The dresser includes a first swingable member mounted on a frame for pivotal movement about a first axis and a second swingable member, having a tool thereon, mounted on the first member for pivotal movement about a second axis parallel to and laterally displaced from the first axis. Control means permit the first swingable member to be fixedly connected to the frame or to the second swingable member, the angular oscillation of the second member occurring about the first axis when the first member is nonrotatably connected relative to the second member and about the second axis when the first member is nonrotatably connected to the frame. The control means also include means for permitting the first swingable member to be nonrotatably secured to the frame in a plurality of positions for permitting relative lateral displacement between said axes.

    摘要： A device for dressing an arcuate surface on a grinding wheel wherein a diamond tool is rotated about an axis on a transversely pivoted platen to form the arc and adjusting screw means extends along the axis to transversely pivot the tool in order to adjust the distance of the tool from the first axis.
