Hi Michael,
This will help me solve a machining question that I would like to answer in another forum. I hope you dont mind.

This is a screenshot of a cylinder with a .5 hole cutout and a fillet of .125 put on it. The fillet becomes variable and the direction that is used to do this will answer my machining question.

This is a top view and the topmost edge of the cylinder is what reflects the fillet radius of .125. The bottom part of the fillet is larger. Is this due to the fillet doing a "Straight down" look through that distorts the radius around edge of the cutout?

In other words, from a machining point of view, if I use a fillet bit, which starts its cut at .125 on that top edge, and follow it around keeping the bit "Vertical", when it got to the bottom it would naturally be cutting more material and create this variable? The other option would be for me to look at following the edge with a 4th axis rotation.

Maybe Danny could jump in here and give me a small lesson. I would mucho appreciate it.

Thanks,
Burr
