Curved Dining Chair cnc-style wedged mortise joints

Normally I publish project that are pretty worked out, but I this case I make an exception. This dining chair is Version 6 of a design process, that is likely to be continued. I had the opportunity to make a life size prototype on a Holzfraese at Koch-Mannes Maschinenhandel in Schweinfurt. It was cut out of 18 mm plywood using a 4 mm single flute end mill at unbelievable 4500 mm/min with only two cuts (9 mm depth per cut). This is clearly not a machine for the enthusiast hobby maker, but it just great to try it out. The wedged mortise joints work like on my Doll High Chair but they are flush with the surface when they are hammered in. I did a 6 mm roundover using my small handheld router and sanded the parts before assembly.
