Manufacturing

Turning designs into real parts — casting, forming, joining, cutting, printing. How parts are actually made. Learn casting, forging, welding, machining, CNC programming, grinding, industrial additive manufacturing and practical 3D printing — with the process physics, calculations and design-for-manufacture rules that decide cost and quality.

• Casting — Casting pours molten metal into a mould shaped like the part. Learn sand, die and investment casting, patterns and allowances, gating and risers, solidification time (Chvorinov's rule), and common defects.
• Forging — Forging shapes hot or cold metal by compressive force. Learn open- and closed-die forging, hot vs cold working, grain flow, true strain and flow stress, forging-force estimation and design rules.
• Welding — Welding joins metals by melting and fusing them. Learn arc processes (SMAW, MIG/MAG, TIG, SAW), heat input, joint types and symbols, weld strength calculations, heat-affected zone, distortion and defects.
• Machining — Machining removes material with cutting tools. Learn turning, milling and drilling, cutting speed/feed/depth, spindle speed, material removal rate, cutting force and power, tool life (Taylor), surface finish and machining time.
• CNC — Computer Numerical Control automates machine tools. Learn machine axes and coordinate systems, G-code and M-code syntax, work offsets, tool compensation, feeds and speeds for milling, CAM workflows and precision.
• Grinding — Grinding removes material with abrasive grains for high accuracy and fine finish. Learn wheel specification, surface/cylindrical/centreless grinding, wheel speed, specific energy, G-ratio, dressing and grinding burn.
• Additive Manufacturing — Additive manufacturing builds parts layer by layer from digital models. Learn the seven ISO/ASTM process families, metal powder-bed fusion, DED and binder jetting, energy density, supports, post-processing and design for AM.
• 3D Printing — A hands-on guide to desktop 3D printing (FDM and resin). Learn the workflow from CAD to slicer to print, key settings (layer height, infill, walls, temperature, speed), materials, tolerances, G-code basics, estimating time and cost, and troubleshooting.
