I want to make the Path like above picture.

 

But I do not know how to make a Contour_area of NX CAM.

 

What should I do?

 

 

I've attached a file.nx1.jpg

One way is to WAV link the part, delete the angle face with Synchronous Modeling and then pick those faces to machine.

From what I gather your problem is that it is not cutting the air? From my days in mastercam we would extract surfaces from the body, extend surfaces and then trim. NX should be able to do the same thing. Hopefully somebody can give a better solution where you don't need to modify geometry.

Using NX 8.0.3.4

With "roll over edges" turned off in the cutting parameters, NX will strip the path that moves over the edge.

 

You can turn this on and use a trim boundary to get the path you expect.

Without the trim boundary, NX might not keep tangent to the edges of the milling area.

You can try first without the trim boundary to see if it is really needed.

if you can wait for NX 10.0.2 there will be a option under "Cutting Parameters" --> "Strategy" --> "Extend Path" check the radio button "Extend Across Undercuts"

Re: I have Questions About Contour Area..

@FDB is right. This was added to allow you to revert the the old behavior of cutting air if needed.

The release is planned for end of July, if everything runs well, so you will have to wait for that release date.
