Abstract [en]

Modern manufacturing processes characterized by short series, complex part geometry and high refinement values often demonstrate conditions when traditional quality control (QC) methods do not work properly. The paper presents a prototype system for real-time quality control based on statistical methods and computer intensive techniques. The developed methods and applications are integrated and post-process quality control is applied only to complement and for reference measurements. The proposed concept of real-time QC includes selection and pre-processing of sensor data, process model development, reliability improvement of process data, online verification of model adequacy and post-process evaluation of QC strategies. All these activities are supervised and fed with information from a developed active data acquisition system. For example, integration of correlated sensor information and use of pre-designed decision rules have been applied for online reliability evaluation of tool wear measurements and for immediate adjustment of improper data. The proposed concept contributes to bridging the gap between traditional post-process control and real-time quality control of machining processes. The presented experimental work has focused on process monitoring when strategies for implementing the above methods in quality control applications have been presented and successfully verified. The results obtained indicate the possibility of implementing the developed concept under practical work-shop conditions
