Finishing Operation Help/Suggestions

[howardkinkade]

I have attached a file where I'm trying to get a finish machine operation to work.  It involves undercuts.  The set of operations are in the machining tab.  The setup is named "Top, Bottom".  The first five operations seem to be dialed in fairly well.  The last finishing operation is with a ball end tool.  I have tried 'ramp' operation, but can't figure out how to get it from maching the end of the three tabs.  I have also tried a 'scallop' operation which was successful for a prior operation with a radiused end mill in "scallop 2" operation, but that operation used as a finishing operation here tends to peck around the piece.  

What suggestions does anyone have to do the final machining operation with the small ball mill?

I would recommend using the 3D Contour toolpath actually:

Seth, thanks that works well.  I learned when using 'rest machining' with the shape near complete from previous operation it resulted in hoping around the profile.  Without rest machining works best in this case.  

Maybe you can help with the warning I always get - " lifting retract height to safe height ".  I can't figure out why and how to resolve these warnings.  Can you (someone) help, thanks?

On your Height tab, you typically have the following:
Clearance

Retract

Top Height

Bottom Height

And then on the Linking tab, there's a "Safe Distance" setting.

Most commonly, the warning is generated when your Retract height value is lower than your Safe Distance value, and increasing the Retract value will make the warning go away"
