NX6 Manufacture Variable Fillet Radius Around Aerofoil

NX6 Manufacture Variable Fillet Radius Around Aerofoil

(OP)
Morning All,

I have an issue that my poor little brain cannot handle.

I am scanning a Variable fillet radius around an aerofoil, I have managed to get so far, but I am now stuck.


My issue is I need to tip the tool over at a fixed angle,but still cut circular around the blade, currently the tool is following the radius surface, this tips the tool over to far.

I have attached a file to this post.

Any help on this matter would be much appreciated.

Thanks
      Alan

Thank You.

I've been on this issue for 2 days and had hit a brick wall.

Your example is exactly what I need to cut.

Please could just break down the steps for me, so I can understand the process.

Thanks

Ok.
First I thought, that i will select the airfoil surfaces, and extend them under the variable_contour/surface area/cut area/surface%, but when I tried to select the drive surface from your original model, NX dropped the error message: Cannot build grid.. selection tolerance, etc.
So I made a copy, trim radius surfaces paralel to the cylindrical wall, and I used this as a drive surface.
I defined the projection vector 'tool_axis' instead of normal to drive, try to change it, and you will see why.

Well I'm Back!

I have the need to cut a variable fillet radius.

I've produced a program to cut as per before;

But I appear to be getting a lot of facets around the edges
I've enclosed a picture to show this.

Any input would be really well received

Thanks in advance

Alan
