6 MACHINE TRADES OCCUPATIONS
622.381-018 to 651.362-030

    This category includes occupations concerned with the operation of machines that cut, bore, mill, abrade, print, and similarly work such materials as metal, paper, wood, plastics, and stone. A worker's relationship to the machine is of primary importance. The more complicated jobs require an understanding of machine functions, blueprint reading, making mathematical computations, and exercising judgment to attain conformance to specifications. In less complicated jobs, eye and hand coordination may be the most significant factor. Installation, assembly, repair, and maintenance of machines and mechanical equipment and weaving, knitting, spinning, and similarly working textiles are included.
