Calculate Machining Time and Material Removal Rate
A hole of 40 mm diameter and 50 mm depth is to be drilled in a mild steel component. The cutting speed can be taken as 65 m/min and the feed rate as 0.25 mm/rev. calculate the machining time and the material removal rate.
Solution
Given V = 65 m/min
f = 0.25 mm/rev
D = 40 mm
L = 50 mm
Spindle speed,
N = (1000 × 65 )/ (π× 40)
= 517.25 rev./min
Breakthrough distance,
A = 40/2 tan 59 = 12.02 mm
Total length of drill travel, L = 50 + 12 + 3 = 65 mm
Time for drilling the hole = 65 / (0.25 × 520) = 0.50 minutes
The material removal rate, MRR = (π× 402 × 0.25 × 520 )/4
= 163362.82 mm3/min
= 163.363 cm3/min
