Lead out on multi pass

[Randy Morton @ Clem Industrial]

I am using multi pass cuts on my mill, and I want it to lead out on the last pass. I check the box, and it leads out on the last pass, but only the last pass. Not the 2 other mutli pass 'last passes'... Essentially there is 3 last passes. How do I get the lead out on all 3, but not on any thing else?

Can it physically fit the Lead/In outs on the other passes?

Is it a pocket?

I do this by using overlap, I figure the distance around and plug that into the overlap.

 

I get the pass, the overlap and THEN the lead out

I usually extend the part geometry (line or spline) the full diameter of the cutter when I run into that problem. Eg: If using a 1/2" endmill, extend the geometry 1/2". If the start or end point of the chain is an arc, I will usually add a line to the end of the chain.

David, no it's not a pocket. I am just creating a flat face (with a 5" facemill) on a round part, with a 45 deg. shoulder on one side. The other runs out off the part.

 

I could extend the line (which is what I normally do), but I have been experimenting with actually using the solid that was provided for me and not drawing all over it. As such I take their line and see how I can manipulate it within the toolpath itself.

 

As far as the overlap goes, it says in the help file that it is how far the tool travels past/off the part to leave a cleaner finish. Does this mean you want to use this without the actual lead out?
