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., \3 l8 S3 ^% p$ q0 \
NOTE: CS=1000 ft/min for carbide insert used. % m1 v* P. k; n6 h \/ Q* y. r* Q; z- Q) M' \9 u
so RPM(1)= - |- f* L; f v2 o; x* e: l. d. m
RPM(2)=" i0 N% j/ D5 A; ^, H' q
RPM(3)= 2 E4 I/ A* ~. Q, A1 X RPM(4)= 5 q' A! |6 F9 \& j" p% f% q) \& G( b
