Cutting silhouettes into vinyl records. This was a first shot at it. Thinking pretty sweet clocks
Besides the kids fishing line breaking off, there are some small spots/holes where the vinyl (or whatever a record is made out of) got pretty gummed up, and as you can see the cut itself got hot on the edges and took on a bit of the spoil board dust as well.. The endmill was a 1/32" two flute down cut. 30 ft/minute feed rate, 0.025" per pass, and the dewalt 611 on its lowest speed.
Any advice on how to minimize the heat and melting? shallower passes, slower/faster speed rate, faster rpm, different mill?
The endmill ended up with a pretty good glob of hard plastic on it too but she kept on cutting and didn't break.
