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.: y! N' t5 J1 } @6 N
NOTE: CS=1000 ft/min for carbide insert used.+ x7 `3 r! T$ w+ M3 @8 E' x
1 ~6 d7 v& z. Y
so RPM(1)= $ J0 C! e+ E: V5 B$ D' L+ T9 l! Q RPM(2)=$ z3 V" n* w, M/ ~
RPM(3)= * v, M+ {$ a- e/ _ H5 ^6 F% z0 y RPM(4)= ' \4 @6 h+ m" Z4 ~" g0 h' P9 u; f
