d) Correct the wrong sentences if found 1. Drilling, turning, and milling use rotating multiple cutting-edge tools. 2. Knurling is performed on a lathe, but it is a metal forming operation rather than a metal removal operation. 3. Friction between tool and chip tends to cause portions of tool material to adhere to the rake face of the tool near the cutting edge. This formation called a 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 a proportional stress and strain. 6. if stress value were mesured during a tensile test, the higher value and important in manufacturing processes is the engineering stress. 7. Drawing is a compression proces in which the work metal is forced to flow through a die opening, thereby taking the shape of the opening as its own cross-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 close tolerance, and surface has a characteristic oxide scale. 10. The plastic region of the stress-strain curve for a metal characterized by a proportional relationship between stress and strain. 11. The difference between the true stress-strain curve and its engineeing counterpart lies in the elastic region. 12. Bulk deformation processes are generally characterized by significant deformations and massive shape changes; and the surface area-to-volume of the work is realively high. 13. Drawing; is a compression proces in which the work metal is forced to flow through a die opening, thereby taking the shape of the opening as its own cross-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?[
