d) Correct the wrong sentences if found1. Drilling, turning, and milling use rotating multiple cutting-edge tools.2. Knurling is performed on a lathe, but it is a metal forming operation ratherthan a metal removal operation.3. Friction between tool and chip tends to cause portions of tool material toadhere to the rake face of the tool near the cutting edge. This formation calleda built-up edge.4. Metal forming applies stresses that exceed the ultimate strength of the metal.5. The plastic region of the stress-strain curve for a metal characterized by aproportional stress and strain.6. if stress value were mesured during a tensile test, the higher value andimportant in manufacturing processes is the engineering stress.7. Drawing is a compression proces in which the work metal is forced to flowthrough a die opening, thereby taking the shape of the opening as its owncross-section.8. Flash in impression-die forging serves no useful purpose and is undesirable.9. Disadvantages of hot rolling are that the product cannot be held to closetolerance, and surface has a characteristic oxide scale.10. The plastic region of the stress-strain curve for a metal characterized by aproportional relationship between stress and strain.11. The difference between the true stress-strain curve and its engineeingcounterpart lies in the elastic region.12. Bulk deformation processes are generally characterized by significantdeformations and massive shape changes; and the surface area-to-volume ofthe work is realively high.13. Drawing; is a compression proces in which the work metal is forced to flowthrough a die opening, thereby taking the shape of the opening as its owncross-section.04/a) What are the difference between cold and hot forming?[b) What are the disadvantages associated with milling processes?[e) How does finishing differ from roughing operation in turning process? -d) How does sheet-metal forming differe from rolling and forging?[
