Proto Tech Tip - Sheet Metal Design Clearances

[@kmihhh]

Many thanks for your useful videos, subscribed! Kindly let me know if my calculations for typical clearences in millimeters below are correct? +/- 0,13 mm - for laser cutting +/- 0,25 mm - for bending +/- 0,08 mm - for powder coating - which makes it necessary to leave ~0,46 mm of space between parts of an assembly? I'm just trying to wrap my head around the numbers as in another video you mentioned that you typically leave 0,01 inch between parts (~0,25 mm) - kzbin.info/www/bejne/iKmcZniYo8SKgZo. Many thanks for your response in advance!

Hey Mikhail! We checked with our engineering team on your question. What you listed above our worst case tolerances for each process, however they are typically not at the larger end of the tolerance. We have found through years of testing that the .010" (.25mm) of space between parts works best for simple designs. However, of course, with an increased number of bends, this tolerance should be adjusted accordingly. Our engineering and design service team can assist you with allowing for proper clearances between parts if you are ever unsure. Once you have your design files all ready to go, send them over and they can review!
