28
Q

Effectiveness

A

amt. of structure removed per unit of time

29
Q

Efficiency

A

amt of energy utilized in cutting, not wasted as heat or vibration

30
Q

Efficiency increases with

A

higher speeds and lighter pressure and air water

31

Q

amalgam an composite prep-versatile

A

pear shaped

42
Q

Spaces between blades

A

Flutes

43
Q

Each blade has

A

2 sides (Rake and clearance)

44
Q

Each bur has

A

Three angles (Rake, Edge, Clearance)

45
Q

Most important design of Bur

A

Rake Angle

46
Q

Negative Angle

A

Most important-allows burr to sweep but not dig-rake face ahead of radius from cutting angle to axis of burr

47
Q

clearance angle

A

behind the rake angle, increased allows less friction

48
Q

Spiral blades

A

increase cutting efficiency at high speeds

49
Q

Cross cut blade

A

Increase cutting at low speeds

50
Q

Number of blades

A

larger gives smooth at lower speeds

51
Q

Flutes

A

increase efficiency by removing debris
