Re: [CAD_CAM_EDM_DRO] How do I rout a sharp inside corner?

there was a thread on this here about year or two ago
if you take a sharp pointed tool and tip it at a compound angle so
that it reaches into the corner you can remove the radius from the
corner of the pocket by plunging down and then out to the sides
a 60deg tool tilted at 45deg from vertical in both X and Y will do it
make a cone of paper and test fit it in the corner of a room to see
how it works out
a plunge router base with the router tilted and guide fences to line
up with the walls of the routed pocket would let you clean up the
corners by hand but it would take a 5 axis machine to do it in one setup
(or 4 axes and 2 setups ,or 3 and 4 if you tilt the work)
