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.6 V4 Z& T$ m4 B/ f2 C
NOTE: CS=1000 ft/min for carbide insert used. * O0 f* M0 y. @' l& a/ H; P0 V6 e9 W" c$ M

RPM(2)= + M' w+ u' c' m8 \ RPM(3)=$ W4 |; _3 e- W% O1 e5 W( P& m

谢谢指教。
