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. # }8 f) y0 K' k* `; eNOTE: CS=1000 ft/min for carbide insert used. 8 O- p# T( X( K: a5 T/ Y! n9 [% l6 f8 e2 ]# P9 c. _( h% J
so RPM(1)= 5 I* Y8 [9 T5 U3 C8 ?
RPM(2)=: w) ^/ o' U, \, D
RPM(3)=, [% k# @3 U* b% g
RPM(4)= * {+ s$ M# g! g8 C, k* p V; M8 ?8 Q- ]谢谢指教。
