  • Orthogonal dressing of grinding wheels
    Patent number: 4624236
    Abstract: In dressing a grinding wheel having a non-cylindrical contour, the wheel is moved in a path corresponding substantially to the desired wheel contour by first and second CNC controlled slides while a single point diamond or diamond roll dresser is rotated by a CNC controlled rotary mechanism through selected angles during traversal of the wheel therepast to maintain a vertical reference plane containing the centerline or mid-plane of the diamond dresser point or radius substantially orthogonal to a vertical reference plane containing a tangent to the wheel contour path. Maintenance of the orthogonal relationship between the single point diamond dresser point or radius and wheel contour path during traversal results in the desired wheel contour being accurately dressed.
    Type: Grant
