In-Process and On-Machine Measurement of Machining Accuracy for Process and Product Quality Management: A Review

摘要

In-process and on-machine measurements are used to evaluate a variety of machining factors and conditions as well as the work done on the machine tool. With the increasing complexity of machining processes and greater requirements for accuracy and precision, the demand for advanced methods for process optimization has also increased. To meet this demand, process quality management (QM) requires an expansion of manufacturing metrology to include comprehensive closed-loop control of the machining process. To eliminate the effects of disturbances on the machining process and adjust the control quantities to optimal values for robustness, in-process and on-machine measurements are very essential. In this paper, we review technical trends in in-process and on-machine measurements for process QM and conventional quality control (QC) of products. Spreading measurement targets and applications are comprehensively reviewed.
