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. 5 {3 C9 O3 }1 L J2 P, MNOTE: CS=1000 ft/min for carbide insert used. , L" q) @. z& v0 W H' {/ o7 Q) e. C: N+ S) z; X
so RPM(1)= , w2 w) J6 G6 Y# y- L
RPM(2)= % t5 D, e* @- p; R {' O RPM(3)=; }4 x6 E V+ G. _1 k# D5 v
RPM(4)= ( M/ N' Y/ B) O8 l ' J$ J: D. X4 s2 c; I3 o谢谢指教。
