The Bird Saga Tell-All: Here's the story of how I got my first $300k+ PO and turned my little race parts shop into a 24/7 CNC production facility (w/ pics!)

Story involves big risks, air mattresses, overloaded circuits, overfilled chip bins, A+ friends, and an industry legend.
October 2018 - My friend Scott posted on FB that he was looking for a CNC shop. I said "me!" and he told me I couldn't handle the volume (he was right).
Nevertheless I replied "when do you want me to start?"

Okay, time for a DFM roast so all you engineers can see how machinists think. @emm0sh volunteered this part, I don't have the time to do a full write up so I'm just gonna live tweet me going through it, exposing the sins, and optimizing it

(1 of ?) Off the bat, we have the cardinal sin of zero radius internal pocket corners. A round tool can't get into a corner. Some of the others are radiused so I'm just assuming it's a mistake and i'm going to note that I'm making this change for later

Machining Apple's Vision Pro Headset
Apple's manufacturing processes are some of the best in the world, and shrouded in secrecy with the exception of their occasional manufacturing videos. Based on the clips, let's break down the machining shown in the latest video step by step. Extrusion - The vision pro headset starts as an extrusion which we see in the opening shot. Molten aluminum is pushed through a custom die to create bars (usually 12ft) of the outside profile.

From there, an automated saw cuts each bar to proper length for machining.
