Before programming the CMM: define what you will verify

Copy the TXT worksheet to edit it, or print this guide from your browser. Use verifiable references; enter “pending” for missing information and explain “not applicable.” Link evidence by ID without copying confidential files. There is no connected form or data submission.

Does not define a valid strategy for every geometry. Does not authorize machine motion, guarding changes, setup, measurement, or release. Specifies no tolerances, calibration intervals, settings, or regulatory compliance. Technical decisions require the authorized owner and applicable documentation.

FICTIONAL EXAMPLE — PLAN-DEMO-CMM, component INSERT-DEMO. A characteristic identified as F-DEMO is to be reviewed. The drawing is stated as revision B, while the received model is revision A. Alignment is labeled “automatic,” without a document reference. No dimensions or tolerances are supplied. Review outcome: plan pending; confirm the drawing/model pair and document alignment with the responsible reviewer. No program, run, or part is approved. All names, revisions, and events are invented.
