Z level finishing does not finish final depth pass

[TPPJR]

It does not finish the last pass at final depth. It stops about an inch or so from completing then either goes to the next flat or stops if it is the end. It does not finish either at the level of the pockets nor at the bottom of the part.

Attached is the .xfa file zipped.

Any suggestions? Thanks for all the help a couple of threads ago to get me to this point.

Thomas,
Perhaps I am not following you but it seems to simulate fine here ???

Rest Robot looks OK too.

Are you referring to a problem while machining ?

Thomas,

On the final pass change the Approach Style to Radial and enter an appropriate ramp on/off radius. This method will also provide better results on this type of part.

With OneCNC-USA suggestion I see what you are talking about now.

Yes it did fine in simulate when I used the radius but I do not like the plunge it has to do into 1/2" of uncut stock to get to the proper depth before the radius in.

Why doesn't follow boundary ramp in work?

What radius are you using ?

Thomas,

See this file..you can use radial approach. If you sketch a start point, you can force it to plunge into an area that does not have stock left..

Ramp boundary is really not for a part like this..as it ramps to depth and then returns to the start of the ramp..so what ever was under the "ramp area" does not get cut...

OK, thanks, I will try this when I get home.

One more thing. When the program is finished with the first flat (the pockets) it goes out to the boundary of the second flat (perimeter of the part) and continues to machine. The problem is that from the first flat to the second in x/y there is stock material that is full thickness. The 1/2" bit plunges into over a half inch of stock. Is there a way around this?

Thomas,

You just need to adjust your boundary for the first operation to clear away that material..

Sounds easy don't it????????

Can you show me using this which you did for me the other day? It gouges on the second flat here too.

Help with profile

Thanks,
