I am CNC routing foamed PVC 12mm with aluminum laminate. Iím doing this in two passes but am having problems keeping the aluminum edge clean. The aluminum is face down on spoilboard so we can insert holes for mounting purpose. We are currently using 1/4" super O cutter from Onsrud but canít seem to resolve the problem. Does anyone have any suggestions?
From contributor M:
The best suggestion is to view the two materials as separate operations and cut the foamed PVC away with the spiral O, then do the aluminum laminate with tool, feeds and speeds more appropriate for it without the foam.
