How to Calculate Bend Allowance and Bend Deduction with SendCutSend

[@pawanraghav5178]

Best video on youtube with clear concepts. Thanks for clearing the doubt about k-factor

[@fzj8022]

Thank you, I haven't found any clear information on this all from one source let alone a video explaining it

[@sendcutsend]

Awesome, glad we could be of assistance ;)

[@fastindy]

Great stuff, the music isn't necessary for future videos though. The content is plenty interesting on its own and easier to hear that way!

[@sendcutsend]

Noted!

[@buyanjan6548]

Thanks for information. But if I were you I would first test and then derive k factor. Then just insert that kfactor to fusion. It will do rest of the work. Your calculation depending on k factors. K factor varies by different materials.

Great information. Very helpful. 👍

Such a awesome explanation video on the internet about sheet metal bending. Sir may I have the formulation for locate the right spot of the bend line ?

[@vink809]

thanks, i got clarity on BD, BA & K FACTOR

[@jeyaprakashp4432]

Sir how to locate the bend line ?

[@razoreater616]

The calculator shows the base at 2”. Wouldn’t the base be 6”?

reasonable explanation but why did you have to overlay the audio with a guitar riff on repeat at the same volume level as the guys voice

Hi, thanks for the video. I was having a play around with the bending calculator and I am wondering which way to make the bends for the deduction to work? Say if I was wanting to bend a U shape from a strip of steel with a specific inside measurement - which way do I make the bends for eg. fold one end, flip the work around 180 deg and fold the other or fold both bends from the same way?

[@sendcutsend]

Hey there! We don't work off of inside measurements but you can enter the outside dimensions in each of the base and flange sections with the bend calculator. You just need to be sure they mind our u-channel ratios. sendcutsend.com/bending/

How do you calculate Bend Radius?

[@sendcutsend]

We calculate bend radius based on material and thickness for best results. We have the bend radius listed on each respective material page on our website: sendcutsend.com/materials/

[@morphik1220]

Why is the K-factor 0.4? Your website states 0.43 for 0.080" 5052 Alum? Is the Bend Allowance 0.2466" or 0.1326"? Your bend calculator states the latter. Additionally, neither of those two numbers is obtained when you utilize that formula (90*(pi/180)*(0.125*K(0.080))). Not sure if that formula is correct, On a positive note, your calculator is very handy and it has yielded me correct dimensions to use in CAD.

Thanks for your comment. This video was created a while back and some things on our site may have changed, we'll investigate and update the video if needed.

Yo why doesn’t the calculator work anymore?

[@vijaypalli3688]

wow sir that's g8

Excellent tool but not very helpful if you're outside of the US All material options are in inches which don't line up with metric options
