Just a quick video showing my approach to HDPE. Roughing is done at 5.2mm DOC, 10mm/s feed, 3mm/s plunge, single flute 1/8" bit, DeWalt 611 at 1.5-3 on the dial. Finishing pass done full depth 10.4mm, 8mm/s feed.
I feel these are still very conservative settings but these parts came out amazingly accurate, for me that is most important.
