I'm working on a project where I need to create essentially an oversized pegboard out of 3/4" plywood, with each hole being 0.52" in diameter.
I'm able to nest all of my panel designs onto two 4x8' sheets quite snugly, which means that the panel designs themselves are in the neighborhood of 48" wide by either 30" or 60" or so long. The attached screengrab should make a little more sense with those dimensions 🙂
I'm thinking of using a 1/4" or 3/8" spiral upcut end mill and a peck drilling operating to quickly drill out the centers of each hole, then come back with a similar sized compression cut end mill to do a circular finishing pass on each hole to get the diameter nice and accurate, and the edge to be clean and smooth. Now that I think of it, I may jump up to a 1/2" end mill for both operations, since my holes are just slightly over 1/2" anyway. Same questions though.
I'm able to work out the peck drilling operation no problem, but I'm having trouble figuring out how to set up the second operation to finish all of my holes. From the Fusion 360 Help docs, I see a Circular pocket milling operation that sounds promising, but when I use it in the software the machining time jumps up to well over 7hrs - making it quite expensive for me.
Does anybody have some clues for how I can make my holes in a more reasonable amount of time using the operations in Fusion 360?
