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.% b, Y/ z* {4 |* M$ V7 x
NOTE: CS=1000 ft/min for carbide insert used. 5 w% u8 z! T7 i+ r; U8 u3 g6 i) h! ?9 d4 y/ a+ e% Q4 g
so RPM(1)= ; U% d: l. r# s* O RPM(2)=, n% Z8 u/ q; v( P u
RPM(3)= 9 f4 ^; c R( I6 \) q% s( M- T8 {/ x& M RPM(4)=5 s! a+ F" p% e7 j4 L: m- q4 t4 a
