I am cutting Sintra with a 1/4and 1/8bit and its not coming out clean. I am having to clean up the edges with sandpaper. Any one know whats agood size,upcut or down cut,and feed rate that would give me clean finished edges.
I’ve cut a fair bit if pvc and single flute endmills are the way to go. I use the default feeds and speeds for hard plastic in CC and that usually yeilds a nice finish with little sanding necessary as long as the endmill is sharp.
