Dark Factories? Of course you thought there wasn't anyone on the floor. They were hiding in the offices while management pretended to turn the lights on for you. Let me guess -- you just finished the McKinsey Quarterly deck on lights out factories, and now you think humans are going away because you saw a couple Fanucs feeding pallets into CNC mills while management waxed poetic about the future of manufacturing. You're going to believe that right up until your first ECN comes through and you have to scrap fifteen hundred fixtures because a twenty three year old design engineer in San Jose wasn't taught in their overpriced engineering university that hard internal corners are stress risers and cause parts to fail in cyclic loading. Then it'll become your problem. While you're dealing with that, you'll look around and notice that the lights in your "Dark Factory" have been on a lot dealing with these issues. You've had to hire more people than you thought for machine maintenance, and you don't even want to think about the very well lit shipping department in the back. Surprise -- another issue, the well staffed and well paid QC department is saying that half of your parts and assemblies are either OOS or failing ORT. You turn the lights back on. Then you'll finally open up ASME Y14.5 and really read it this time, and not just skim over it again to figure out why an angularity tolerance isn't measured in degrees and see that the cause of your process capability going to crap was because a process two vendors upstream was slowly coming out of spec. After that, you'll think you've figured things out and crack open Shigley's to read about Hertzian contact stress and realize that the super hard and expensive unobtanium carbide lathe tooling you forced down your vendor's throat was going to end up adhesive wearing away anyways despite the softer aluminum parts they were cutting because it didn't matter what your hardness differential was. Daddy Bharat Bhushan was always going to get you. You then implement a tool change schedule and then it hits you. Dark factories aren't happening because dark factories aren't a robotics problem. They aren't even just a manufacturing problem. They're an operational, finance, and everything under the sun problem. Recursive feedback mechanisms? Sure, pal. The only thing here recursive is this story. If I had a dollar every time I heard it, well, I guess I could afford an actual factory.

CAD is the easiest part of my job as an engineer

i’m trying my best to summarize my dislike of 3d printing because it comes in waves. it boils down to: it’s not a serious process because of simple physics on one hand, it is a deeply useful technology for non-structural prototyping. but so are hammers and neither are revolutionary enough to “bring manufacturing back to the united states” it’s anisotropic. e.g. you can’t analyze it to determine requisite part strength against things like yield or ultimate stress it’s slow - andrew mccallip showed you can CNC parts faster than 3d printing them recently (link below) it’s susceptible to cold flow (creep) in a way that makes injection molding look like 4340 the unit economics never make sense past onesie-twosies, even if the physical properties weren’t a blocker it isn’t water tight (i mean, come on) but my biggest complaint is that it inspires lazy thinking. we live in the most exciting time ever for manufacturing. i can click a buy button on a site like sendcutsend and get production grade aluminum or steel parts in days note that i didn’t complain about strength - that’s the least of its problems anyways, to summarize, get better at mechanical design and design with real materials so we can truly reindustrialize. thanks for coming to my ted talk

normalize visible tool marks in consumer products

*slaps motor* you can fit so many degrees fahrenheit in this thing

mechanical engineers:

text to cad is insufficient because even the best engineers need a whiteboard to convey intent to each other accurately

i'm building a team

bringing manufacturing back to the states implies bringing engineering back too most US engineering jobs today are project management

how are they doing this

having to CNC something is a failure on your part as an engineer to make it out of sheet metal

if ironman had been true to life

everything is sheet metal
