A part's accuracy in machining is verified by measuring it against design specifications using precision tools. This process involves the use of calipers, micrometers, and other measuring instruments to ensure that the dimensions and tolerances specified in the engineering drawings are met. Precision tools are essential for obtaining accurate measurements, as they can detect even the slightest deviations from the desired dimensions, which is critical in maintaining quality control in machining processes.

This method recognizes that a part must meet specific geometric and dimensional requirements to function correctly in its intended application. By precisely measuring and comparing these dimensions against the established specifications, machinists can confirm that the part has been manufactured within the acceptable tolerances and is capable of performing as intended in assembly or in its operational environment.
