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 V) g: J! w# O, l% B
NOTE: CS=1000 ft/min for carbide insert used. # n! q; L$ `* h. Z' F1 Y: `# p* O# M% s$ N1 ], ~
so RPM(1)= & Z8 c6 ^4 C z J
RPM(2)= $ Y1 r2 m% L! z4 i1 q/ \ l RPM(3)= 0 F; v! K( L6 X2 t. ^8 a S RPM(4)= , { V! O5 { a$ @- P- V$ P1 |, G# O8 {7 N- ^
谢谢指教。
