This is the part I find most fascinating. What you’re seeing isn’t a typical 5-axis pass. It’s a 3-axis CNC machine, but with a fully articulating cutter head — one that tilts, dips, and pivots mid-cut to reach angles even full 5-axis setups can’t hit without complex fixturing or reorientation.

That’s not to say it’s easy. Because of the tight clearances and extreme angles on the spoke windows, each spoke has to be milled from the outside in — resulting in a total machining time of 31 hours per Vera wheel. Fortunately, I run these 24 hours a day, so I'm able to get these done in the same time as others.
