Making a part for an organ I’m building. The intention was to use a 1/4" bit to cut out the shapes and then go back with a 1/16" bit to square out the corners so that I’d only need to round the tenons slightly by hand to put it together.
Used a pocket rather than contour toolpath to enable rest machining.
What I’m seeing is that it wants to recut the entire outer path area of each piece already cut with the 1/4" bit with the 1/16" bit, taking approximately forever. The interior pockets are behaving as expected with the small bit just notching the corners. What have I done wrong?
The rest machining part of the operation is cutting the complete pocket. I enlarged the pockets and the simulation shows it only cutting the desired areas.
Also I see you have tabs. You don’t need to have them if you are not cutting all the way through the material
Thank you! That seems bizarre, it’s not as if there’s not room for a 1/16” bit in a 7 mm slot. I wonder why it feels compelled to do that?
Yes, I am planning to completely cut out the parts. The tabs don’t appear in the simulation. I’m guessing they don’t work when you’re using a pocket cut. Hope the double stick tape works!
It’s not that there’s no room for the 1/16" endmill. I think its cutting the complete pocket because the bottom is not flat from the 1/4" endmill pocketing operation. I could be wrong…
Going from a 7 mm offset to an 8 mm offset eliminates all the excess travel on the second pass. Don’t see how that would make the bottom any flatter, but who knows. Thanks for your help, at least I can move forward!
