Recently, I took an interest in the design and engineering of CNC machines. Looking through Youtube, you can find numerous examples of other people's work with varied quality and performance.

The question is, if one were to do some reading on how the big manufacturers build and design machining equipment, where would be a good resource to find this knowledge?
 
Start with concept! What machine are you going to build? What is the secret sauce that is going to make yours better faster stronger cheaper than the others? This is important to remember, as it can get forgotten as edits progress.
Then start assembling a mountain of cash while you design and learn: a large mountain.
Tool builders (cutting tools/consumables) are your friend. They have people that know what ideal conditions are. Some will work with you to find choke points of these conditions. Ideal conditions are what you as builder need to make. If it means changing physics- you do it.

check growth of your cash mountain.
usgs And bureau of mines have lots of good reading and poorly done graphs of material properties.
Double your cash pile- you need a mountain.
The standard books principle of machine design, fundamentals of cutting... a few out there at your local library.
Now just edit design to meet all the above.

The big builders have people. Software jockeys, mechanical designers, fabricators and machinist, and office staff to source and pay for parts. And sales people. And mountains of cash.

Cash is not everything. Voortman builds pretty machines, great fit and finish, top of the line components- and they suck. They built a machine from list of parts with a jar of ragu for sauce.
A dragon coper uses cheap parts, hardware store fasteners, a almost non-speakable controller - and works great for years with limited effort. Dragon has secret sauce in software- they built machine as accessory to create real environment for their software.

These are for mechanical cutting machines. Similar approaches to others like laser. While most builders go heavy and manly eagle laser went carbon fiber and wicked fast. Brother went small spindle fast while others go heavy and stout. Secret sauce first, the rest is just library, drawing, coffee and cash.

Simple answer. Get a job working for a MTB and keep your eyes open. Even if it is just a floor sweepers job. But using your cell phone to take pics may cause loads of rectal pain. May not be able to get your phone back on your own. Set it to vibrate when called. Docs in OR may ask you if you want it removed, or just charged.
