Re: create a cut out vs pocket

Seems like your looking for an operation called a Contour. Does these "D" shapes break-out the bottom of the stock? If so you can drill and entry hole, then use a jigsaw to cut out the Internal "D" material leaving some wall material. Then come back around with a Mill and do a contour finish pass for your final shape. This process should eliminate center cutting and pocket chip removal.

I can "pocket" it but that creates a whole bunch of chips that I don't really want or need to create. What do I call this cut out area instead of "pocket". The goal is to make a couple trips around the perimeter of the cut out area. THANKS!
