4 topics across all disciplines.
Engineering drawings and why tolerances exist
How a manufacturing drawing communicates a part — views, sections, the title block, and the one idea underneath all of it — no dimension means anything until it carries a tolerance.
Machining processes
Turning, milling, drilling, boring, grinding and broaching — what each is good at, how cutting speed and feed decide tool life and finish, and why chatter, work hardening and burrs cause more scrap than accuracy ever does.
Press tools and die design
Blanking, piercing and forming tools explained — die clearance and the break-and-burnish edge, progressive versus transfer dies, tonnage and shear, and why tool steel selection and strip layout decide the cost of the part.
Forging and grain flow
Open die, closed die and upset forging compared, why a forged component outperforms a machined or cast one of the same steel, what flash and the parting line are for, and how grain flow decides where a part fails.
