Rough grinding is effectively removing as much material (stock) as possible. Surface finish is of minor importance in this process. Removing redundant material from the cast, forged, or welded pieces can involve leveling or smoothing edges and giving the piece the required shape. It can also mean removing material to form or enlarge a cavity.
