I'm quite new to router-based CNC, but am really enjoying writing some exploratory g-code programs to help with woodworking projects. I have a BobsCNC Evolution 4, have a quality 1/4" spiral upcut bit installed, and I feel like I am getting the hang of it. But I have a fundamental question that I can't see to craft the right forum or google query to answer on my own:

If I use this setup to cut profiles/shapes out of, say, .75" thick hardwood, do I need to worry about making the profile cuts wider than the 1/4" endmill diameter, to clear chips or avoid rubbing? I know that I need to program ramps, and a slow progression of step downs, but I can't seem to figure out whether I can just cut the perimeter in one diameter-width or whether I need to widen? And if I need to widen, whether I should worry about fanciness like trochoidal toolpaths?

Any help here will be greatly appreciated Best,
Zach
