Hi Everyone - I am new here and relatively new to CNCs. I have carved a few things but still consider myself a beginner.
I want to build some drawer fronts like the images below. I think they are called half moons. I want to carve the profile piece with the CNC if possible. If the piece had 90 degree sides it would be an easy profile cut. However, I they are angled back on the top and bottom so it can act as a drawer pull and would be easier to pull.
Perhaps cutting a template and using a chamfer bit to cut the angles?? But I was hoping to cut it on the cnc face down with a v-bit to get the angle, but not seeing bits with that depth of cut (3/4”).
Any ideas on approach, bits, etc. would be much appreciated.
Thanks,
Todd

I think you’d probably want to cut the semi-circles with a straight cut bit, then use something like a dovetail bit to cut the relief.
You will want to make the relief cut a full depth cut in one pass and it’ll be easiest to have the path start off the drawer face and follow through until it clears the other side completely, so it doesn’t plunge or retract on the drawer face.
Searching more, here’s one that’s 1" DOC — can you use a 1/2" shank in your CNC?
14° is a common dovetail angle but there are others.
Whether you make the cut in a single pass might depend on the wood and whether it is subject to tear-out.
It might take some experimentation with the wood to know whether you need to have the dovetail cutter a bit higher in Z than the straight bit you use for the rest of the recess. You could do test cuts in the waste material and sneak up on it to get your process set.
You can google finger router bits and undercut bits to see a wide array of shapes. Here are a couple examples. You can do the bulk of the work with a straight bit and then a pass for the finger recess.
