In the world of Production Open Die and Step Down Shaft Forging, blacksmiths will take a piece of metal, heat this metal for a set time and temperature until it is red hot, before it is rotated, hammered and carefully elongated in unison to reach a specific shape or size.
The starting piece of metal, sometimes called a Billet, Blank or Mult, can be tricky or time-consuming to calculate backwards from the customers forge prints.
Use this Reverse Forging Calculator to save you time, energy and money, while easily calculating the Billet.
This forging process is truly a work of art, as the metal has to be worked by multiple blacksmiths while the temperatures are above their recrystallization temperatures.
For example: If a Billet is cut too short, all the heating and hammering time will be wasted when the final part cannot make its finished size. Having said this, if the Billet starting length is too long, then everything left over gets cut off and scrapped, including the extra labor and heating time.
All that energy usage, labor and furnace real estate can be very costly to throw away and, again, this is why this program was engineered. Use this RFC software to help calculate the starting length of the piece of metal to achieve your forging goal with minimal waste.
Once you calculate your Billet size, click the E-mail button to send your report to your supplier or saw operator.
To save money and material, look through your left over pieces before cutting off of a new full bar. Then use the Diameter Override to reverse calculate, using the new diameter, the formula keeps the same desired weight and solves for the new length that you will need. A powerful time saver.
The adjustable scale loss used in the calculator is the percentage of material that will flake off during the forging process, 5% per heat cycle with alloy steel should be perfect, but is configurable.
FORGING TIP - Allow enough head length on the 1st Step for safe manipulator clamping.
FORGING TIP - If a Test Piece is required... Use this calculator to add extra length to the last step on one of the parts and adjust your quote offline.
FORGING TIP - If you are quoting RINGS, Use a 1-Step Shaft and add a center hole diameter.
SALES QUOTING TOOL - You can also enter your shops price per pound to help quickly estimate your job quotes and click the email button to send your reports.
QC TOOL - Click the QC Visual Heat Chart button to open the Quality Assurance thermal chart to help prevent over heating of parts, you can also click the Heat Ranges button to list the thermal ranges for various metals.
