How parts are actually made. Metal 3D printing, CNC, injection molding, casting — the tolerances you can really hold and the defects that show up in production.
A reference manual for working engineers
One engineering concept per video, at the depth the job actually needs. Every page follows the same five steps and is built to still be right in five years.

Statistical Process Control (SPC) Explained: Signal or Noise?
An operator nudges the tool after each shaft that comes out big or small, and the shafts get worse. How to tell a real change in a process from its day-to-day wobble: common and special cause, the X bar and R chart, why control limits are not tolerances, how to read the signals, which chart fits which data, and why chasing a size widens the spread.

Why things break and how to catch it on paper first. FMEA, root cause, fatigue, Weibull, SPC, inspection.
How a design gets from sketch to production line in one piece. DFM, GD&T, tolerance stack-up, design reviews, industrialization.
How a factory knows what is happening on its own floor. Sensors, PLCs, SCADA, machine vision, predictive maintenance.
The things that don't change. Stress and strain, material selection, process capability, bearings, bolted joints.
What is happening under the hood when you hit simulate. CAD, FEA, PLM, CAM, and where the model stops matching the part.
