can any help trying to get clean 5 axis tool path for feature on model

[crunichie]

hey guys 

looking to see if any one can help me get better /clean 5 axis tool path on the model feature attracted.

have tried the 5 axis flow and 3d contour (with multi axis turned on )

flow as you see get good path one side but not on the other  in setup 2 (also using offset surface )

then tried the 3d contour  with added multi axis had it doing the multi axis but can get it to do it again on setup 3 using a offset surface 

tried also surface offset of the feature to go past so get sharp edge. but only some time get it to work any help or tip be great

One issue that multi axis has with most of the toolpaths (steep and shallow, 3D contour...) is it wont calculate undercuts so you might have to try different wcs's to get it to calculate right. Flow might work with some tweaking.

so try moving my datum  then re gen path ways ok i give that try thanks and let you know if that worked

thanks

You can use a tool called accessibility analysis (Under inspect) to check. Like so:

The red area's fusion wont cut (when using multi axis with contour or steep & Shallow) because its considered an undercut. 

I made an axis perpendicular to that cone, then made a plane on that. Set this as your new datum for that toolpath.
