Mutiple-axis roughing issue

[Tedarencn]

Hello experts,

I am not sure why to leave the material for multiple-axis roughing, please refer to the screenshot and Mastercam CAM file.

Your help will be appreciated.

I have seen this also, not as profound as your example. It looks like an overlap issue. A solution would be welcome.

Try adjusting your step-over, and step-down values. Also, try adjusting your Stock-to-Leave values by small amounts. Sometimes changing 0.1 mm stock, to 0.11 or 0.012 or 0.0014, (adjusting the right-most digit), can change the outcome significantly. Same story with adjusting the values in the other direction. 0.099 or 0.098 or even 0.08 or 0.085, can totally change the results of the Toolpath algorithm. 

Have you attempted to analyze the model? With a Solid, you can sometimes get small problem areas that affect Toolpath generation. For these problem Solids, I will often create surfaces from the Solid model, and use these to drive the Toolpath. 

Is it possible that you have geometry selected for the Toolpath, which is on a Level that has been turned off? Use the Right-click option to "unselect all surfaces/faces", and then manually add surfaces/faces one-by-one, to be sure there isn't a 'phantom surface' selected for the Toolpath.

I have gotten models that are probably junk and optirough leaves weird islands and skinny spires.

 

I made surfaces and it was fine

This file is from YouTube. It likely is a problem with the model.
