Detailed Solution
Download Solution PDFCutting speed is the speed at which the cutting edge passes over the material while cutting and is expressed in meters per minute.
\(v = \frac{{\pi dN}}{{1000}}\)
Where v is cutting speed (m/min), d is diameter (mm) and N is in rpm
Calculation:
Given:
v = 35 m/min, d = 24 mm
\(v = \frac{{\pi dN}}{{1000}} \Rightarrow 35 = \frac{{\pi \times 24 \times N}}{{1000}} \Rightarrow N = 464\;rpm\)
