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. / u: L \# K2 F" _# RNOTE: CS=1000 ft/min for carbide insert used.* V3 c t! L7 e) I7 e1 t, u
' X* S* {' ~% g: h4 u1 w; z
so RPM(1)= 7 Q! J, S& w- E# m
RPM(2)= ' Z5 ], c' R7 W2 Z! X( r RPM(3)=% D4 X2 r0 A/ _ s
RPM(4)=# ?: |6 g( f$ ?7 j }8 B- v4 ^0 g/ {

谢谢指教。
