Undercut Tools

[Brian B 74]

I have forgotten how to do this. I need to describe a double angle cutter to cut a small undercut. It needs to be profiled but the cutter won't go into the undercut.

 

Here is the file

 

The geometry for the form cutter is on layer 100. Any help is greatly appreciated.

Flowline or SF Contour.

Doing a sf contour. Can't get it into the undercut.

Brian, I cannot see the file because we don't have X6 installed, but we typically use a "standard" chamfer mill and phony geometry on the top of the part for something like this, then adjust the Z to get her where she needs to go. This is a hack, I understand, but it typically works.

Flowline seems to do the trick.

Using undefined tools can be a pain when doing undercuts...

I ended up describing the tool as a slot mill and using a custom profile on a level. I couldn't use the double angle tool so I ground up a back draft cutter and that did the trick. I had to scale the cutter to a radial 1" dim so the back plot would be accurate.

 

Thanks for all the help and ideas.

just did a simple contour with the right tool def.. yes i know the tool looks rough but you can grind the tool relief at the top how ever you need but just make the tool and contor it other wise you can use a key cutter and use parlle z but that a 5 axes toolpath and can post out as 3 but you need multi axes capabilitys
