Hey guys, I cut circles on my CNC all the time but now I've got a question. I need to make a D1-8 adapter for a 6" 4-jaw flat back chuck I bought for my big lathe so I figured I'm cut the holes for the pins and set screws as well as rough the ID and OD on my CNC. For thge center hole I figure I'd drill a big hole on the manual mill and then just loop a circular pocket cycle til I cut through the bottom of the plate. For the OD I figured I'd cut a circle say 0.060-0.100 deep and loop it but I'm afraid of breaking the endmill what if I modifiy the circle loop to cut say 0.250 over size then to size before looping down to the next depth? I plan on using a 0.500" carbide long flute endmill, do you think I'll be able to clear the chips enough to keep from breaking the endmill in such a deep slot? Should I run a bolt circle drill cycle a little bigger than the OD first or will the interupted cuts give me trouble? What if the bolt circle was oversize enough that the endmill is always cutting something and just use the holes to clear the chips? I figure I could drill holes and leave only about 1/8" web to support the disk will I do the ID. I have to do two bolt circles anyway for the pins and set screws.
Anyone have a better idea? What would you do?
All of the finish work will be done with the adapter attached to the lathe spindle, well except for facing the back of course for than I'll just chuck it in the big 3 jaw. BTW the adapter will be about 9" OD with an ID the size of the chuck.
