11. Material Removal Processes A family of shaping operations, the common feature of which is removal of material from a starting workpart so the remaining part has the desired shape. Categories: – Machining – material removal by a sharp cutting tool, e.g., turning, milling, drilling – Abrasive processes – material removal by hard, abrasive particles, e.g., grinding – Nontraditional processes - various energy forms other than sharp cutting tool to remove material
