primary

function

analyze data and plan sequence of operations and set up and perform a variety of machining operations on a limited number of large manual and cnc/dnc vertical and horizontal milling, drilling, broaching, boring, and turning machines. Machine parts with numerous steps, diameters, and fits to exacting tolerances of finish, perpendicularity, concentricity, parallelism where details are not normally provided. Meet requirements of lower level job code with emphasis on learning how to operate more machines.
