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. # O, T' M' q) h' i/ PNOTE: CS=1000 ft/min for carbide insert used. ! i. @# E( b% b3 E7 D; t1 t' v5 \* w5 Q" K
so RPM(1)= 2 h! ^5 ]6 H) H8 W" H
RPM(2)=, A, H4 x! A# a
RPM(3)=3 n l6 q7 j' r8 p/ n! Q, V
RPM(4)= . U4 ^- c2 q! p7 R; q7 _8 b1 D: G, o4 U2 g
谢谢指教。
