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.* E, F3 l. H v
NOTE: CS=1000 ft/min for carbide insert used. 6 ~; ^5 K1 n+ o) P7 W/ p* } _2 v; p: U0 t
so RPM(1)= 6 O, T2 u9 P- |3 H RPM(2)=2 R% k$ T5 z8 \
RPM(3)=/ j' ^3 E( p4 z1 [
RPM(4)=: K& Y5 I4 }& s/ a" |/ m9 Z, c
( \2 n5 ?1 ^. a$ L0 x2 |$ Y
谢谢指教。
