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. $ V" n0 Z& z5 ]7 d) PNOTE: CS=1000 ft/min for carbide insert used.$ Y* `$ c0 I- G2 l, ^
, w! ^9 X' e; m% ~6 p8 r
so RPM(1)= ) L7 g. |: h$ w+ L5 Q' ]
RPM(2)=( F" g2 a) x( E$ F+ K0 l/ _
RPM(3)=; e) W1 j- m8 O5 x! G
RPM(4)=5 d* c% F/ ^1 d# K) N% c
8 p9 i% F9 H3 _4 j
谢谢指教。
