A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).

I know that forging reduction ratio is defined as the ratio of the original to the final cross-sectional area. However, I've recently encountered the suggestion that if an ingot is upset to increase the cross-sectional area before being forged to reduce the cross-sectional area, the reduction ratio is the ratio of the upset cross-sectional area to the final cross-sectional area.
