Abstract
Systems and methods are disclosed herein for dressing and trueing grinding wheels. A laser may be directed substantially tangential to a grinding surface of a grinding wheel. The laser may be a continuous wave laser and may ablate material from the grinding surface. The laser may move relative to the grinding wheel in order to ablate shaped surface profiles into the grinding surface.
Claims13
A method of dressing a grinding wheel comprising:
- directing a laser substantially tangential to a grinding surface of the grinding wheel;
- rotating the grinding wheel;
- forming a ribbed surface profile in the grinding surface with the laser, wherein the forming the ribbed surface profile comprises:
- translating the laser across a width of the grinding surface while ablating material from the grinding wheel;
- and
- increasing a depth of ablation by moving the laser toward an axial center of the grinding wheel during the translating;
- removing the ribbed surface profile with the laser;
- and
- forming a curved surface profile in the grinding surface with the laser by translating the laser across the width of the grinding surface while ablating material from the grinding wheel.
