Like most quality manufacturing companies, in order to maintain accuracy and stay within tolerances, you likely inspect your parts at various times during the machining process. And you likely create inspection instructions to document the results. There are many ways to create a series of inspection instructions. But, in the absence of an electronic "in-process" model of the part, they are manual methods that require a certain degree of technical expertise. These time-consuming methods are performed with limited knowledge of the state of the in-process material and are therefore prone to error.
