4th axis (B table) Swarf Milling

[Sup3rscript3d]

I'm new to NX (coming from Mastercam) and I'm having some trouble wrapping my head around swarf milling. I've created the following part:

I'm currently only interested in milling the pocket in the center. It's essentially just an extruded slot normal to Z with 15deg drafts on the ends and a fillet on the floor. What steps might one take to create a finish milling operation that makes use of the rotary axis to side mill the entire pocket wall?

The CONTOUR_PROFILE operation is usually used for swarf milling.

Thank you, thats a very good start. The generated toolpath is essentially exactly what I'm after. I have a few questions about customizing it.

How do I:

- Modify the start and end points

- Control the tool axis along the cut (i.e. fanning)

The documentation of the operation should cover this, see NX Help => Manufacturing (CAM) => Manufacturing Milling => Surface Contouring => Variable-axis Surfa...

You control the points in the drive method dialog use the wrench beside it to access it.Drive Method

The tool axis is controlled in the tool axis block.Tool Axis

Hope this helps.
