  • Patent number: 7168351
    Abstract: A process for generating a curved surface on a workpiece with high speed is disclosed, in which an acceleration of a slider is set to a predetermined desired acceleration while a rotating velocity of a work spindle is made varied to keep the acceleration of the slider as constant as possible. Rotation of the work spindle and movement of an X-axis table are made synchronized with the movement of the slider having the desired acceleration to generate a preselected desired curve on a surface of the workpiece, which lies in perpendicular to a Y-axis along which a cutting tool moves in and out, thereby shortening the cycle time it takes for the curve generation on the workpiece.

  • Patent number: 6865787
    Abstract: A numerical control (NC) processor with an onboard grinding unit is disclosed in which a workpiece is first cut in a preselected contour with a Y-axis cutting tool, and then subjected to honing operation intact whereby both the cutting and honing operations can be performed with just a single processor with high-speed, high-acceleration. With the NC processor, the Y-axis cutting tool is mounted on a sliding base above an X-axis table in a way allowed to move back and forth in a Y-axis direction, while a grinding unit is installed in close proximity to the sliding base. A slider moves back and forth in synchronized relation with rotation of a work spindle to first let the Y-axis cutting tool cut the workpiece into a preselected contour, and then cause a buffing material of the grinding unit to grind a work surface of the workpiece into a high-quality surface finish in conformity with a programmed contour while the workpiece remains held intact in a chucking device.
