Frequently asked questions
What is UF (utilization factor)?
UF = finished part mass / purchased blank mass. Closer to 1 means less waste. The calculator shows UF including allowances and process losses.
How is the standard bar diameter chosen?
From the standard nominal size series for round bar: the smallest standard diameter that fits the part plus machining allowances.
Can I calculate a forging blank?
Yes — the Forging profile applies upset ratio Y = 1.3, metal burn-off, stock round-bar options for purchasing, and billet mass per batch.
