Do you have a Machinery's Handbook?

thanks for your help i know about bend allowance and deduction actually i have a problem with three roll bending machine, when i want to bend a sheet practically i do it easily with three roll bending machine in shop but when i want to input my data in inventor its confusing because on the sheet i have 3 bendig with different rediuses. how can i measure bend rediuses on sample when i dont have them ?

Do you have an image, url or ipt that illustrates your problem?

Not sure about a 3-roll bending machine. There should be a "Calculate k-Factor" function in one of the utilities. You need to work with a pre-measured strip. It should give the details on how to do this in the instructions (should be one of the tabs).

i attach the picture i want to bend sheet metal like the sheet back of bucket (red one) how to measure it and please schematically do it in inventor to understand how can i do it tanks.

The k-factor will vary from machine to machine and from bend/forming process to bend/forming process. A proper k-factor is really determined from each process and each machine to acheive an accurate k-factor.
The k-factor is really an approximation of the line length along neutral axis of the bent part. In theory it should be in the middle of the part but different process's will cause it to move slightly from the centerline.

the best answer for 3roll bender mechine calculations is arc formula and the .5 k factor is best astimation for open bends.
