I’ve found most of this by searching the forum, but I’m double-checking to make sure I got it all right:
I’ve got parts I need out of thin, colorless, clear acrylic. 1/16" or 1/32" would be ideal, preferably the 1/32". Do you cut 1/32" acrylic? Or should I design to 1/16"? (I’m fine going with 1/16".)
I saw somewhere else that the acrylic sheets are actually metric in size, and that a 10% variation within a given sheet is to be expected. So I guess a better question to ask than the one above is if I should design to 1.5mm and expect a +/- 0.075mm tolerance on thickness?
For thin acrylic you mentioned the laser kerf is 0.005" to 0.010". Will it tend to be on the thinner side for 1/16" or 1/32" acrylic? The tolerances on these parts aren’t insanely tight, but I’d like to tab/slot the parts if possible, so the more information the merrier. Also, I saw that the laser’s centerline falls on the lines we put in our DXF files, so the kerf is more or less evenly split on both sides of the line. Is this correct?
With kerf allowances and material thickness variations, I was planning to make my slots .066" wide for 1.5mm material. Did I do this math right?
Finally, I was planning to assemble these with cyanoacrylate. I don’t forsee a problem there, but if you have any horror stories with this thickness of material and CA glue, let me know.
Thanks a bunch!
