I am using NX 11. I am looking best way procedure how to program a head bust in 5 axis (3+2) machine.
This is my scenario.
I used mill contour for roughing (3 axis program)
2nd process plan is i will rotate the A axis into 90 degrees. then i need to create simultaneous program for the B axis. My problem is i dont know how can i provide simultineous program because I'm a beginner in NX 5 axis (3+2) programming.
Thank you for helping me.
To point you in the right direction, read about "projection vectors" in the docs.
Variable contour is how I would do the finishing. You would want the drive surface to be a cylinder around the model. The part surface would then be the part.
Be preprared for lots of trial and error. It can be hit or miss. Sometimes I get the path I want in 5 minutes, sometimes it takes hours.
There is a preview project in NX12 that will allow facet part geometry on some Variable Axis operations. I can put you in contact with the product manager if thats something you are interested in. For NX11 and below you will need to convert the facets to triangles. I have done this before and it works just fine. There are some free programs linked to in the forums or I would be happy to convert if you dont have runtime license.
Here is a sample file that shows variable contour on a facet model as per your youtube link.
Here are some key points to follow.
Must be non projection style drive, I used Guiding Curve
Must be a convergent model so use the convert function if it's not already a convergent model
The cut area must be clear, so divide the body so you have goot cut area. The whole body won't work
NX12.0.2 with ENV set, contact your local support to organise this.
I used a section curve as the guiding curve.
As the guiding curve is offset along the convergent body you wont get constant along rotation axis slicing.
As this functionality is under preview please expect some trial and error to overcome any trouble you have. We can help if you are struggling to solve something but it may take some time or some workarounds for now.
