You begin with an engineering print and 3D model in hand. You translate GD&T callouts into a clear measurement strategy, then build a robust CMM routine to verify every feature that matters. When a drawing leaves datums undefined, you design a practical scheme that makes the measurement traceable and repeatable. Before lunch, you remediate an existing CMM program to tighten cycle time and improve reporting. Later, you jump on the floor to coach an operator through a tricky comparator check, then return to compile an FAI and a capability study, making sure data tells a clean, defensible story.
