Given data:
- Diameter of the drill bit = 20 mm
- Rotational speed of the drill bit = 500 rpm
- Feed rate = 0.2 mm/revolution
- Thickness of the Mild Steel plate = 20 mm
To determine: Depth of cut in this drilling operation
Explanation:
The drilling operation involves the removal of material from the Mild Steel plate by the rotating drill bit. The depth of cut is the distance that the drill bit penetrates into the material during each revolution.
Formula:
Depth of cut = Feed rate / (pi x diameter)
Substituting the given values,
Depth of cut = 0.2 mm/rev / (pi x 20 mm)
Depth of cut = 0.2 / (3.14 x 20)
Depth of cut = 0.00101 m or 1.01 mm
Since the thickness of the Mild Steel plate is 20 mm, the drill bit needs to penetrate the material completely to create a through hole.
Therefore, the depth of cut required for drilling the through hole is 20 mm.
As the calculated depth of cut is 1.01 mm, multiple revolutions of the drill bit are required to achieve the desired depth of cut.
Hence, the correct option is (c) 10 mm.
- Diameter of the drill bit = 20 mm
- Rotational speed of the drill bit = 500 rpm
- Feed rate = 0.2 mm/revolution
- Thickness of the Mild Steel plate = 20 mm
