Understanding Sheet Metal Design - Press Brakes

Question asked by Paul Fox on May 6, 2016

When designing a sheet metal part how do you work out the inside bend radius in relation to the tools that are being used?

 

I have designed a variety of sheet metal parts which I plan to send off to a local firm to be manufactured (via press brake). It's a fairly complex part and if my blanks are wrong I will need to pay twice for the re-work.

 

I have been sent a list of tooling they have but it does not mean much to me at the moment.

 

I've read a few things online but I'm struggling to make sense of it. If you fold using the same tools at different angles (90 & 45 degree) does the inside radius stay the same?

 

Much thanks in advance for any help
