5. Metal shaping process:  Rolling

6. Metal shaping process:  Bending

7. Metal shaping process:  Forging

8. Metal shaping process:  Spinning

9. Metal shaping process:  Drawing

10. Metal shaping process:  Shot peening

11. Metal shaping process:  Extrusion

12. Metal shaping process:  Coining

13. Metal shaping process:  Forming

14. Metal Joining Process:  Welding

15. Metal Joining Process:  Brazing

16. Metal Joining Process:  Soldering

17. Metal Joining Process:  Riveting

18. Difference between Soldering, Welding and Brazing  Welding is done between two same metals.  Whereas brazing is used to joint different metals at very high temperature.  Soldering is same as brazing, except it takes place at comparatively low temperature.  Welding: Welding rods  Brazing: Filler metal rod  Soldering: Tin alloys

19. Metal Cutting Process:  Turning

20. Metal Cutting Process:  Planing

21. Metal Cutting Process:  Grinding

22. Metal Cutting Process:  Shaping

23. Metal Cutting Process:  Hobbing

24. Metal Cutting Process:  Drilling

25. Metal Cutting Process:  Threading

26. Metal Cutting Process:  The boring tool is a single-point cutting tool, which can be set to cut the desired diameter by using an adjustable boring head. Boring operation Boring

27. Metal Cutting Process:  Slotting  A milling operation that cuts a narrow part into the surface of a workpiece

28. Metal Cutting Process:  Reaming

29. Metal Cutting Process:  Gear Cutting

30. Metal Cutting Process:  Broaching

31. Metal Cutting Process:  Shaving

32. Metal Finishing Process  Lapping

33. Metal Finishing Process  Electroplating

34. Metal Finishing Process  Honning

35. Metal Finishing Process  Metal Spraying

36. Metal Finishing Process  Polishing

37. Metal Finishing Process  Anodysing

38. Metal Finishing Process  Buffing

39. Metal Finishing Process  Parkerizing

40. Properties of metal Mechanical & Physical Chemical Electrical

41. Residual Stresses  Residual stresses are stresses that remain in a solid material after the original cause of the stresses has been removed.  Residual stresses may be advantageous or disadvantageous.

42. Residual Stresses  Advantages: Corrosion resistance & better fatigue behavior  Disadvantages: Less Accuracy Crack and twist occurs Change stress limit

43. How to remove residual stress? Solution: By heating the metal below RECRYSTALIZATION TEMPERATURE.

44. Recrystalization  Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains and grow until the original grains have been entirely consumed

45. Recrystallization Effect Hot Working of metal Recrystallization temperature Melting Point COLD WORKING OF METAL Normal temperature Temperature Rise

46. Grain Growth
