A large majority of machining is being able to access the areas you need to cut. The sides of the frame would be in the way if you were trying to cut those round features.Machinelet here, can you elaborate on this part? What was he doing and why didn't it work?
Most frames have their pockets cut from the top with end/ball mills and slotting tools, sometimes EDM. But all those need clearance above/below or both. There are right angle milling heads but they are very very large....
Even if they didn't know machining a CAD person should have known better. Even the "never-held-a-hammer" artsy designers would have never handed something over like that.
Maybe they were intending to 3d print the frame all along? Then that just shows how little they knew about the technology. There is a reason companies haven't got rid of their machine shops in favor of 3d printers.
When they came upon the same problems of machinability for the 2nd prototype they just broke components into more components. Yes its actually cuttable now, but it's clear they didn't talk to a machinist about "should" it be done that way. They were probably getting paid per part/ per hour so it doesn't matter to them.
By the 3rd prototype they were still fucking around with the limitations set from the start. It takes a certain amount of boldness and naivety to think you're gonna make a magazine from scratch. Even the big boy companies know better. Thankfully this at this point they started talking to an engineering firm.
The name alone is enough to make me think that they had a serious ego problem.
