Springback 22 gauge 1020 Steel

[FLtenwheeler]

Hi

I need to calculate the springback when making a 90 degree bend for 22 gauge 1020 steel with a 3/64” inside radius.

Can someone help me with this or point me to a spreadsheet or other calculator.

Thanks

Try bending a piece?

For a "One-Off" job, I have simply made the required bends and checked for squareness. Sometimes a little bit of nudging gets it all square.
No math. Just "Do."

If a production run is planned, a more precise setup is expected.

I am making forming dies to use with a chunk of hard rubber. I was wondering how much back draft I should plan on.

I will get some 22 gauge steel and bend it 90 degrees and see what the spring back looks like.
