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.; p% B# J8 ?. X- u
NOTE: CS=1000 ft/min for carbide insert used.; Q+ M0 o( x& M1 h" u
( n% N% c$ b% Y4 L
so RPM(1)= 4 _, m/ n6 e, x( v RPM(2)=$ |# }. x' @. J$ L" l. R
RPM(3)= : ?! I- X9 ~$ ^5 A3 R4 s% T RPM(4)= 1 I. {& r3 r2 r+ u+ M1 M( J [6 m7 G1 q; t0 E1 M4 Y4 k谢谢指教。
