I hope this won't be taken as too far off forum/topic but I was wondering if someone could tell me how to calculate a radius in a rectangle's corner to accommodate the true .assigned,rectangles corner.(e.g.-you've got a 3"X4" rectangular pocket that you want to fit something 3"X4" in. You use a 1/8" cutter which creates a radius. How much extra,(understanding there will be some slop in the actual length and width of the desired rectangle)compensation of the width and length necessary to get the corners of the rectangle to fit in this pocket as closely as possible. Thanks,Keith

Thanks Rich. Yes,that's it. I just wanted to be able to derive that .0183" in the case of the .125" cutter for different size cutters,using an equation,since I come across this a lot.-Keith
