Engineering and TechnicalEngineering Drawing and Geometric Tolerancing
A drawing is a contract between design, manufacture and inspection, and an ambiguous one is settled by whoever makes the part rather than by whoever specified it. This course covers reading and producing unambiguous drawings. Delegates work through projection conventions, views and sections, dimensioning practice and the difference between a dimension that controls function and one that merely records geometry. Tolerancing follows: limits, fits and the accumulation that ruins an assembly. Geometric tolerancing is taught properly, including datums, feature control frames and the symbols in common use. Surface texture and welding symbols are covered. The course closes on drawing interpretation for inspection and on revision control.
Course objectives
