Hello everyone,
I have been cutting Alum, with my CNC router which some good success (profiling). The cut finish is okay but could be improved, and part of the marks I see are sometimes due to the multiple steps I am using to separate the part.
I know I can always go back and so a "spring pass" or a full depth finishing pass at a very slow feed. Regardless, my biggest challenge is removing the tabs I am using to hold down the parts.
I found these threads which suggest to drill holes to screw the parts to the spoil board and not use tabs etc, but what happens when the actual part does not need or can't have any holes, or only has one hole.
