How to find the bend radius? Or how to give the bend radius?

Thank you , keep watching.

Thanks

Thanks for your sharing

You are very welcome

Thanks, welcome

Bending allowance and bend deduction is the initial calculation of design to avoid upcoming issued in sheet metal fabrication. Calculating bend deduction, for the material you will have to remove from the total length of the flanges in order to arrive at the proper length in the flat pattern. hope it helps

@steeban kraj Noted, i will make it as a separate video soon

Ok sure will do soon.

Yes, it can be measure by three ways. 1) if the part is small, you can use profile projector to find the actual radius. 2) if the part is too big but the radius is small, you can use rubber cast method. 3) There is radius gauge available for each size, you can compare with the matching gauge to find out the actual radius.

Thanks for your feedback

Yes, you are correct. K factor value should be 0.4 Since the radius is less than 3 times of thickness. Thanks for correcting me, will update this info in this video. Cheers

im not sure bro

Hi Bro , good question. See this videos description has the link. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--T8cMn198m0.html

Sure

Hey bro this is how you find the k factor on your press break ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hA5K7JiYCcA.html

please give more details

"The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend."

Please refer 5:26 - the statement mentioned on this side "the location of the natural axis varies and is based on the material's physical properties and its thickness" so, it not constant as always the the K factor is not half of the thickness. Please refer 7:40 i have told that usage of these calculation. what is the required total length needs to cut before bending based on these calculations. Yes, i din't mention the use of bend deduction in this video. "The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend."" Thank you!

bro doubt iruku

Actually it has to be consider as number of degree needs to bend so multiply into no of degree not as angle. Refer below link for more information www.engineersedge.com/bend_allow_calc.htm

@@zeroto1009 ok thank you

10mm inner radius + 5mm wall thickness

@@zeroto1009 35 MM LENGTH AFTER BEND + MATERIAL THICKNESS IS 5 MM = 35+5=40 , 40-25 = 15 . SO THE SETBACK VALUE IS 15 MM

@@gashatech1655 yes both calculations are correct
