Proto Tech Tip - Sheet Metal Design Clearances

Every week, Team Protocase is bringing you a Proto Tech Tip video, where we'll give an informative look at a particular aspect of sheet metal fabrication and CNC Machining.
This week, Brian is here to talk about sheet metal design clearances.
This video will show you the ins and outs of Protocase's manufacturing when it comes to clearances and best practices to make sure your design functions exactly as you envisioned

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!
