rough and finish pockets with two different sized tools?

Postby gadget-evilusions » Tue Mar 13, 2018 5:07 pm

Is there a way to rough and finish a pocket function with two different sized cutters without recutting a bunch of air?

I made a pocket pass using a 1/2" mill to clear out the large portions of stock on this brick panel I am making 20 of right now. It leaves some areas that the 1/2" can't hit. I'd like to go back with a 1/4" and clear out those missed areas without having to recut everything the 1/2" already did.

I am making these 4 x 8 brick wall panels out of 3/8 mdf on my router right now.

I am using a 1/2" bit to rough out all the large areas, and then a 1/2 82 deg to do some of the detail work.

There are a few spots the 1/2" can't get into when roughing, so I'd like to run a 1/4" bit in to clean that out. the problem is that I can't figure out how to do it without recutting all the air the 1/2" has already cleaned out. Is there a rough and finish function that I don't see that allows you to run multiple bit sizes for efficiency? Or a mill remainder function that will pocket out areas that haven't been hit by another mill yet?

In the pocket toolpath there is an option to use a large area clearance bit. Check that box, put your 1/2" bit in there and use your 1/4" bit as the regular bit. The program with calculate 2 pocket paths (one named "clear") using the two different bits for you, the 1/2" will "clear" and the 1/4" will go back and "detail" the missed areas. Run them both and that should do what you want.

Be sure to click the "Show advanced toolpath options" box at the top of the pocket toolpath window.
