Make tools, fittings, and small metal pieces used in other products.
Develops gauging setup and surface plate layout procedures, draws patterns and templates, and inspects variety of parts and tools, to provide inspection devices and fixtures for use in machining or assembly, using blueprints, formulas, trigonometry, and precision measuring instruments: Analyzes inspection problem by comparing part with blueprints or sketches, and devises procedures necessary to measure specified dimensions. Lays out part on surface plate or positions in gauging setup to verify dimensions, using master gauges, indexing head, gauge blocks, comparators, verniers, micrometers, and indicators. Develops and draws patterns and templates used to measure curves and angles. Tests surface finish of machined parts, using profilameter. Tests hardness of metal parts [HARDNESS INSPECTOR]. Analyzes defective parts to determine reasons for dimensional variations, such as faulty machining, or assembly procedures, setup, tools, or fixtures. Recommends corrective procedures to design, methods, process, or production engineering departments. Inspects machining or assembly fixtures, tools, or gauges, and suggests replacement or use of new equipment. May approve parts not within specified dimension tolerances. May change allowable tolerances specified on blueprint.
