how would one apply edge treatments to wood ie camfored or rounded edges on the cnc with it being clamped down. Thinking the edging needs to be done on a table router not a cnc or am I missing something.

Set your outside contour to be several roughing passes so you have some room to work and go in with a round over. Or, you can design the round over in your CAD, watch my video I just did on 3D toolpaths with Fusion and pay close attention to the portion about 3D contour as a finishing operation. I used a round over as my example. |

Trust me, vacuum clamping is probably the most secure method next to clamps. Definitely stronger than tabs. If you cut it loose under good vacuum, you'd destroy tabs too lol. I've seen vacuum tables take full width cuts from a 1/2" mill 3/4" deep. In aluminum. |

Well you're going to need the vacuum table itself and then a vacuum pump. Vacuum pump are tricky because the amount of Merc you can pull depends on elevation as well as the the table and material. Really porous woods won't hold vacuum worth a crap.... Matter of fact it just dawned on me, most of your work is wood. Vacuum is not your best option. Go with tabs lol. |

They look just like your standard round over but instead of the big flat top, they go to a point. They work really well. Here's a whole lot of em. |

Yup, they are called point cutting roundovers.
