metalworking tools, using mechanical or hydraulic press, furnaces, cutting and grinding wheels, and
precision-measuring instruments: Weighs cobalt, carbon, tungsten, titanium, and other powdered
metals on balance scale to obtain specified molding mixture. Pours mixture from pans into molds or
into hoppers for automatic feeding into molds in press. Turns valves on press to compress mixture
into billet. Removes billet from press. Sets automatic feed, time, and temperature controls on
sintering furnace. Feeds billets into furnace to fuse metals together. Removes billets from furnace
and cuts and grinds them into cutting tips, using diamond cutting wheel and electric grinding wheel.
Measures cutting edges of tips to ensure attainment of specified tolerances, using gauges, rulers,
micrometers, and protractors. Sets pyrometer controls of heat-treating furnace, and feeds cutting
