Anybody who ever gets far in the Apple interview process knows that you eventually have to submit a "design challenge" and visit Cupertino. The project of packaging 2 AA batteries in an Ipod was tasked, and the above concept was designed and printed by Charles Macdonald in a matter of days in early 2015. It was presented to a group at Infinite Loop offices, a very memorable day. It thankfully did not result in a job at Apple. It's an amazing company, superior products, but it does not look they will know/learn how to build a car.
From design to production: CAD, FEA, CNC, then onwards to the races.
While most subwoofers have a wood chassis, this one off billet aluminum subwoofer was painstakingly detailed in CAD over the course of a couple of months. All the pieces were then precisely CNC, 2 subwoofers were assembled first try.
A client's existing ball marker design was modeled in CAD and a small batch was CNC manufactured.
A putter head CAD model was created and 3D printed, for proof of concept. Payment never received, so this was never brought forward to CNC manufacture.
Though many projects are machined or mechanical, design possibilities are limitless. Charles had to dive right in and bring these textile ideas into CAD. The data was then used for a provision patent and for a first working prototype.
Another golf club head, with new alignment concept was conceptualized in CAD, and brought to life on a 3D printer. CNC was not pursued, at the time, but sintering in metal is becoming more affordable for future projects like this.
