Start your day by reviewing the traveler: confirm prior operation sign‑offs, verify part counts, and pull up the latest drawings and specifications. You reference GD&T per ASME Y14.5, open your CAD/CAM toolkit (Mastercam, Esprit, SolidWorks), and translate engineering intent into efficient, reliable toolpaths for both 5+ axis VMCs and advanced multi‑axis lathes. You design and program the workholding that makes it all possible, run pre‑use equipment checks, confirm gages are in calibration, and keep every action fully documented for traceability.
