Strategy for Post-Process Control of a Machine Tool



Theodore V. Vorburger, K Yee, Brian R. Scace, F Rudder


The automated control of machine-tool accuracy is discussed based on a quality architecture containing three control loops: real-time, process-intermittent, and post-process. This paper highlights the post-process loop. The architecture is being implemented at the National Institute of Standards and Technology under the Quality in Automation (QIA) project. At present, active investigation is being carried out for a two-axis turning center. The QIA project emphasizes the measurement and control of process variables to control the quality of the product. However, post-process dimensional measurements of the finished product play a role in the system and may be used for correction of certain variables. The strategy for the post-process loop includes classification schemes for the parameters in the system, for the error diagnostics, and for the error model of the machine tool.
