I had a requirement to machine a part on four sides of the material. Ok, simple. Except, two of the sides tilted 6 degrees off vertical. To solve the problem, I used my indexer as the hold down and simply rotated it using the MB command to the proper orientation between cuts. Worked perfectly.

Here's the part without any 3D machining in Rhino:
