A drill bit of 20 mm diameter rotating at 500 r.p.m. with a feed rate of 0.2 mm/revolution is used to drill a through-hole in a mild steel plate 20 mm thickness. The depth of cut in this drilling operation is

Question

Accepted Answer

The depth of cut in the drilling operation can be calculated using the formula: depth of cut = feed rate / (2 * pi * radius)

The diameter of the drill bit is 20 mm, so the radius is 10 mm
The feed rate is 0.2 mm/revolution
The formula for calculating the depth of cut is: depth of cut = feed rate / (2 * pi * radius)
Substituting the values, depth of cut = 0.2 / (2 * 3.14 * 10) = 0.00318 mm

Accepted Answer

0.2/(2*3.14*10)=0.0031mm

Accepted Answer

The depth of cut is the distance that the drill bit penetrates into the material during each revolution. 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.
