Managing Grinding Forces and Abrasive Sharpness

2021-11-22  Plowing decreases the material removal rate and increases grinding power, both of which increase the specific energy. Increasing SGE elevates heat in the grind zone, so uncontrolled plowing may cause thermal damage to the workpiece. Threshold power also increases during plowing, corresponding to higher forces needed to fracture the abrasive.
