Machining and Cutting tools

Question 1

Cutting conditions

Answer 1

.

Question 2

Roughing

Answer 2

Quickly removes large amounts of material

Question 3

Finishing

Answer 3

Final dimensions and tolerances

Question 4

Discontinuous Chips

Answer 4

Low Cutting speeds
Large feed and depth of cut
High tool chip friction
Brittle Material
Coating on cutting tip

Question 5

Continuous chips with BUE

Answer 5

Removal of swarf is difficult
Ductile Materials
BUE builds up and breaks off periodically which can affect the cutting surface
No coating on cutting tip

Question 6

Serrated Chip

Answer 6

High cutting speeds

Question 7

Fracture Failure

Answer 7

Unpredictable, Cutting force too high, to prevent do intermittent cutting

Question 8

Gradual wear

Answer 8

Preferred method of failure as it is predictable

Question 9

Cutting tool materials are

Answer 9

High toughness
Wear resistance
Hot hardness

Question 10

Cutting fluids

Answer 10

Wash away swarf

Reduce temperature and friction

Question 11

Facing

Answer 11

Tool fed radially inwardly smooth surface finish,

Question 12

Chamerfing

Answer 12

Putting an angle on a cylinder

Question 13

Parting off

Answer 13

Narrow tool is fed to cut off at the end

Question 14

Threading and Tapping

Answer 14

Tapping is putting a thread on an inner surface and threading is on the outer surface

Question 15

Reaming

Answer 15

Extremely accurate dimension finish for a hole.

Question 16

Face Milling

Answer 16

Tool is fed perpendicular to cutting surface,

Question 17

End Milling and End drill

Answer 17

The cutter is fed from the end, and the cutter width is smaller than workpiece so a slot is cut. An end drill can not drill directly in

Question 18

Profile Milling

Answer 18

Outside periphery of a flat part is cut

Question 19

Pocket milling

Answer 19

Used to mill shallow pockets

Question 20

Fly cutting

Answer 20

Cut a flat surface

Question 21

Slot drill

Answer 21

Can drill into work piece

Question 22

Surface contouring

Answer 22

Curve linear path

Question 23

Shaping and planing

Answer 23

Shaping is when the cutter moves, planing is when the material moves

Question 24

Broaching

Answer 24

Cut a small accurate slot or internal feature

Question 25

Sawing

Answer 25

Cuts narrow slit in material

Question 26

Kerf

Answer 26

Width of the cut it also stops jamming

Question 27

Bandsaw

Answer 27

Continuous cutting, very fast

Question 28

Grinding

Answer 28

Small grit size - Hard Materials

Large grit size - Soft materials

Question 29

Honing

Answer 29

Abrasive method to helps to retain lubricant

Question 30

Lapping

Answer 30

Rubbing two surfaces togethor

Question 31

Chemical Blanking

Answer 31

Chemical erosion of material that is less than 2mm thick, When die and conventional methods cant be used.

Question 32

EDM

Answer 32

Sparking melts the material, Die making, Wire cut EDM for very high accuracy

Question 33

What colour is the oxygen tank and combustion tank

Answer 33

Oxygen - Black

Combustion - RED
