Undercut chamfer

[ari.hemila]

Hi guys,

how do I do the undercut chamfer to the hole end so that it keeps the width of the chamfer constant ?

Thanks

Ari

Hello,

Thanks for posting! Would you mind sharing your file?

I'll add a sample toolpath which will give you an underside chamfer

Hey,

Has anyone ever solved this?

I've run into simmilar problems and other than writing code by hand I havent found another solution.

You need 3D tool path to do 3D cut, Flow.

Well, looks like old thread and OP is long gone or not active at all so this is actually addressed to you since you asked the question.

Flow will work for deburring cross hole edges and making small chamfers on curved surfaces like in above case or chamfering inside edge of cross hole threads .

I haven't had good results machining fillets on curved surfaces, tool path is usually rough in a sense that passes are not parallel and tend to leave inconsistent finish.

Using more passes will minimize chance for missing surface area, passes overlap each other and result in more uniform surface finish. 

Nadam se da ti ovo više ne predstavlja poteškoće.

Thank you for the solution, I will try that.
