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. 7 Q# o' O& l! a- z4 sNOTE: CS=1000 ft/min for carbide insert used.% S( p/ k# v( z% m" k" k
8 s% q& O" D" N& z. }
so RPM(1)= 6 Q3 S3 {0 ^2 a3 b( o
RPM(2)=0 Y% ~; N8 A" {3 ?
RPM(3)= ( k9 X* u) y4 z( H RPM(4)=6 A2 z8 L4 i& P9 v
4 G+ v% @2 K$ z( A
谢谢指教。
