QUESTION: 3

### The regulating wheel of a centreless grinder is rotating at a surface speed of 127 mm/s and is inclined at an angle of 5°, Calculate the feed rate of material past the grinding wheel. [sin5° = 0.087, cos5° = 0.996]

Solution:

The feed rate is merely the component of the velocity in the feed direction, given by
f = Vsinα =127 sin5°
∴ f= 127x0.087 = 11 mm/s

QUESTION: 4

Consider the following statements:
Flutes are made in the drill:
1. To curl the chip lightly for easier removal
2. To allow the coolant and lubricant to get down to the cutting edge
3. To form the channels through which chips can escape from the hole

Which of these statements are correct?

Solution:

Purpose of flutes:
- help from the cutting edge of the drill point
- curl the chip lightly for easier removal
- form the channels through which chips can escape from the hole
- allow the coolant and lubricant to get down to the cutting edge
