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.% r f/ M2 X5 W
NOTE: CS=1000 ft/min for carbide insert used. # ^7 b- Q/ `4 ~5 m$ y( S0 x U$ L8 j4 L4 Z% |
so RPM(1)= - e7 G$ v% D1 V$ ] RPM(2)= & w) s( g( G# x- g% S RPM(3)=( l+ X! m7 W- `0 W/ `* ?) w
RPM(4)= - O! e& t8 @, A" k. r0 r& t" Y% ]9 E% g1 k5 m* T/ z* r4 A/ ?
谢谢指教。
