FAQ

Frequently Asked Questions

Are the original calculator functions preserved?

Yes. The tool pages keep bend allowance, cone/frustum development, cylinder shell blank sizing, unit switching, K-factor presets, canvas drawings, instructions, PNG export, and PDF export.

Can I use the result directly for production?

Use the result as a reference. Confirm material, tooling, bend method, grain direction, and first-article measurement before production.

What is the official contact email?

The only public website-domain contact is support@bendallowancecalculator.online. Partner supplier cards may show their own external-domain emails.
