City Guilds Model Questions Vol1 2018 Engineering Question 38
Practice objective / multiple choice question 38 from the 2018 City Guilds Model Questions Vol1 Engineering examination.
In a turning operation the feed is \(f=0.2\) mm/rev and the depth of cut is \(a=2\) mm. The tool‑life equation is \(T = 200\,V^{-0.25}\) where \(T\) is in minutes and \(V\) is the cutting speed in m/min. The power required is approximated by \(P = 0.2\,V\,f\,a\) (kW). The machine's maximum power rating is 5 kW. Find the greatest cutting speed \(V\) (in m/min) that satisfies both a minimum tool life of 30 min and the power limit.
