Cutting speed:
- Cutting speed is the speed at which the cutting edge passes over the material while cutting, and is expressed in meters per minute.
- It is given by:
V = \(\frac{\pi~\times~D~\times~N}{1000}\)
Where, D = Diameter of milling cutter (mm), N = rpm, V = Cutting speed in m/min
Calculation:
Given:
V = 35 m/min, Diameter, N = 400 rpm
∵ V = \(\frac{\pi~\times~D~\times~N}{1000}\)
⇒ 35 = \(\frac{\pi~\times ~D~\times~400}{1000}\)
⇒ D = 27.85 mm
The nearest value is 28 mm
