Need help with multi-axis curve tool control

Thank you for reading,

 

I'm struggling with this 5 axis curve tool axis control using HAAS Trunnion. The tool-path I'm using is Multi-axis Curve with  tool axis control "Point". Using the point for tool control look okay, but the tool angles which makes a chamfered part edge. I also tried using lines parallel to the part edge for tool control, but the tool path was all over the place. I even tried using a drive surface near the parts center, but I failed to get and good results.

 

The part matl is hydroformed 6061 at .063 thick.

 

Could someone please see if you can get this to work and school me on what it is I'm not doing right. For all I know I could be using the wrong toolpath or this part cannot be multi-axis milled.  

 

 

The MCX-8 file is attached / backup link

Take a peek at this it's not 100% yet but will give you an idea of things to look at, I had to 2 areas, the purple surfaces, that were just out of control, I remade the surfaces and that cleaned up that issue, there are a couple more areas that "may" need some tweaking to get them just right but you will get the general idea

JParis,
Looks like bad geometry was the issue here. I see and understand what you changed. I will let you know how it verified . I see that Manufacturing Specialist suggested using the New swarf toolpath. I'll try both. 
Thank you

Success! The swarf worked great and the code made it through Vericut just fine. Thank you both

 

Thanks for posting up the file with something in it. Also thanks for trying something to figure it out. Lastly thanks for letting us know you got what you were looking for. Can that file be used to make a training video with?
