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. 1 D$ d. L" {! J: \/ KNOTE: CS=1000 ft/min for carbide insert used. ' r( h% \3 H7 a, F z/ `* A0 H& |- M q9 H2 F& O9 H3 |+ h
so RPM(1)= & I0 [7 d9 T* a: P
RPM(2)=/ A7 ?8 X5 K7 a( \0 a' r# H
RPM(3)= ( [% M: T5 q: ^, m RPM(4)=0 {( L# S) ^2 J
3 ? ?4 H: r z4 G0 Y$ k, Y0 L6 }
谢谢指教。
