How to machine using spherical cutter?
(OP)
Hello guys, Been trying to find a way to finish this part with a spherical tool but having problems.Nx 8.0 is not allowing the tool to touch the side walls of the part and sensing the shank would hit the top smaller opening of the part even thou shank is smaller than the tool dia.I am attaching 2 pics.One is of the part and second is the section view to better understand the part.Any help would be greatly appreciated. Thanks

Under Cutting Parameters, Clearances, check the Tool Neck clearance.

You could maybe try a Z-Level Profile op. with the Part selected and the surfaces selected for Cut Area and the cut levels set to scallop in Common Depth per Cut but I'm not familiar with the possibility of undercutting areas with this op. but if you can get this to work make sure in the Non Cutting Moves - Trim to Min. Clearance is checked with a specified Min. Clearance in the engages and retracts or else the cutter may violate the part on these.
I'm sure there is a better way of doing this, maybe someone else can chime in with a better approach.

Before that, I would try Cavity Milling, profile cut pattern, turn off tolerant, turn on undercutting.

I guess what we have now is a lollipop cutter ----- THAT CAN"T DO ANYTHING.
Thanks for the lolipop cutters, I guess.....

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?

You have so much negative to say about NX lets see your software!
