Information model for machine-tool-performance tests

This report specifies an information model of machine-tool-performance test s in the EXPRESS [1] language. The information model provides a mechanism f or describing the properties and results of machine-tool-performance tests. The objective of the information model is a standardized, computer-interpr etable representation that allows for efficient archiving and exchange of p erformance test data throughout the life cycle of the machine. The report a lso demonstrates the implementation of the information model using three di fferent implementation methods.
