Forging Ratio
Forging Ratio
(OP)
Is there a set method to combine the forging ratios for cumulative forging processes? I.E. if there are several forging steps taken, how do I combine the reduction ratios from each step to get the total reduction ration to report?

εN = N · εi
reduction r is related to initial area A0 and final area A, regardless of number of steps, by:
r = (A0-A)/A
and reduction ratio RR for a single step is
RR = A0/A = exp (εi)
or for multiple steps
RR = A0/A = exp (N · εi)

You might like to visit earlier threads on the same topic and the calculate the actual forging work ratio.

If you start with 5:1 forge it 1.57:1 then upset it 1.06:1
= 5*1.57*1.06 = 8.3:1

Hello everybody!
Would the translation of the material have an increment on the forging ratio besides the one coming from the cross-section change?
For example, starting with a cross-section of circular shape and finishing with a ring-shape cross-section (this is, a hole in the middle). Would in that case the forging ratio still be the division of the starting and finishing sections?
I hope I explained myself.
Thanks in advanced.
