I have found that the glues used for the two sizes of plywood are different. Seems 5’ x 5’ is glued with Urea Formaldehyde Adhesive, and 4’ x 8’ is glued with Phenol Formaldehyde Resin. Both glues are industrial.
I learned the glue information through a bad experience with 4’ x 8’ sheet material not getting repeatable cutting with a laser. Even with higher power there would be sections that did not cut. Switching to 5’ x 5’ sheets with recommendation by the laser machine rep solved the issue, lesser power and repeatable full cutting.
And I had a better experience on the CNC with the left over 5’ x 5’ format sheets. Bits seemed to be cleaner after cutting and I could cut at a slightly faster rate.
So, for the cabinet shop and furniture guys that use a CNC, does this make sense? Is my limited sample size on the CNC too small?
And to go on tangent, is either a better substrate for veneer?
