I'm making some boxes with lids. The lids will have a recess that the box fits into. Of course the corners of the recessed portion of the lid are rounded just like the mill I'm cutting the recess with. My question is, how do I radius the corners of the box so that they fit into the corners of the lid. I'm sure I have to use R in the G-code, but not sure exactly how to make the mill cut in a straight line and then curve around the 90 dgree corner and then continue in a straight line again. Any help would be appreciated.
Thanks,
Randall
