I am in the process of designing tool paths for a mantle clock. The side pieces have rectangular openings with arched tops. As part of the design the outside edges of these openings require a 3/16 radius cove for decretive purposes. My question is would a 3/8 core box bit be the choice for this. If so what category are they put in. In Vcarve Pro there is no category to add it to unless i choose round tipped end mills etc. I plan to cut the coves first then use a .25 end mill to make the cutout and leave half of the cove. Speeds and feeds are also a question mark.
