Billet Size Calcs. for filling Dies

(OP)
Dear Engineers,

I am looking for a resource to help me calculate the required ruling section of a forged component to be able to order the correct metal size so that it successfully fills the dies when forged?

Hope someone can help!

RE: Billet Size Calcs. for filling Dies

Since you did not specify open or closed die forging, here is some general information from ASM Handbook, Volume 14A on the topic of open die forging;

Quote:

Production and Practice
Stock for smaller open-die forgings is usually prepared by cold sawing to a length that is computed to contain the required weight and volume of material. Allowance is made for dimensional variations in the cross section of the billet stock. Stock is sometimes sheared to length, but the upper limit that can be sheared is about 152 mm (6 in.) square or round. Large open-die forgings are commonly forged from ingots. Large ingots are sometimes used to produce two or more forgings in which the individual forgings are parted by cutting (cold or hot), burning, or machining. When ingots are used, an additional weight allowance is usually provided for the removal of end defects, such as shrinkage, porosity, and pipe.

This should get you started
