Abstract: Systems and methods are disclosed herein for adding surface features to grinding wheels. A laser may be directed substantially perpendicular to a grinding surface of a grinding wheel. The laser may be pulsed and may ablate material from the grinding surface. The laser may move relative to the grinding wheel in order to ablate shaped surface features into the grinding surface

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.

Abstract: Powder metal alloy engine hardware components may be finished using a combination of roughing and grinding techniques. An engine component may be rough ground with a grinding wheel at a relatively high rate of material removal. The engine hardware component may be semi-finished using a turning process. The engine hardware component may be finished using a grinding wheel.
