A 6.5 inch dia shaft is to be machined on a TURNING CTR to 4.5 inch dia in 4 equal cuts. If CONSTANT CS is selected calculate the RPM at the beginning of each cut. ' P# T, u: ?2 p' ENOTE: CS=1000 ft/min for carbide insert used. & m3 }# h! o+ q# q: b4 o# C( q4 N9 L; D- J4 O/ V1 E+ C6 M8 l
so RPM(1)= , _3 R, E, S* l; g8 a8 \
RPM(2)= # C& z" F0 ]4 D, [ RPM(3)=7 y2 \* F# j# T% U8 f; [! ]- d$ M
RPM(4)= 1 z3 b3 |1 o/ J& m/ e% x1 i ; E h; _7 }: C" n! O谢谢指教。
