Abstract
Inspecting features of an object including measuring features of the master part that represents a desired nominal dimensions to obtain a preliminary set of dimensional data. The preliminary set of data becomes a master data set. The same master part is measured on a second machine to obtain another set of data on the master part. The two data sets are compared and correction data is generated representing differences between the different data sets for the same master part measured on different machines. Subsequent parts are then measured on the second machine to obtain measurement data that is corrected based on the correction data. The application of the correction information provides for the use of 5-axis machines within a desired measurement capability.
