MPP

1. DIscontinuous chip

   • 1. Break into smaller pieces during cutting
   • 2. Cutting brittle material
   • 3. Low cutting speed

2. Continuous chip

   • 1. Long and connected chip produces during cutting
   • 2. Cutting less brittle material
   • 3. High cutting speed

3. Chip breaker

   • 1. Reduce cutting resistance
   • 2. Increase machine performance
   • 3. cause the chip to curl and break off

4. Cemented carbide

   • 1. Extremely hard material
   • 2. Cut hard tough material (alloy steel) while HSS could not do

5. HSS

   • 1. Cutting mid steel
   • 2. cutting at high speed at excellent toughness
   • 3. Used in milling cutters

6. Cutting speed

   • Speed which the work moves with respect the tool

7. Feed

   • Distance travel on the tool from the work piece

8. Depth of cutting

   • Thickness of metal which is removed during machining

9. Coutersinking

   • uses to enlarge conical hole

10. Counterboring

    • used to enlarge the previous hole

11. Reaming

    • Used to have a better finishing hole

12. Independent chuck

    • have 4 jaws
    • Every jaws moves independently
    • each jaw can be removed and reversed

13. universal chuck

    • have 2,3,6 jaws
    • Every jaws moves equally together
    • jaws are irreversible

14. Sensitive drilling machine

    • light-duty
    • <0.5 inches holes drilling
    • Hand feed lever

15. upright drilling machine

    • heavier-work
    • < 2 inches drilling hole
    • hand feed lever & power feed

16. Verticle milling machine

17. Turning machine

18. Drilling machine
