6 MACHINE TRADES OCCUPATIONS
6 MACHINE TRADES OCCUPATIONS
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.
