In-process detection of grinding burn using machine

2021-5-22  The improvement of industrial grinding processes is driven by the objective to reduce process time and costs whilemaintaining required workpiece quality characteristics. One of several limiting factors is grinding burn. Usually appliedtechniques for workpiece burn are conducted often only for selected parts and can be time consuming. This study presentsa new approach for grinding burn detection realized for each ground part under near-production conditions. Based on thein-process measurement of acoustic emission, spindle electric current, and power signals, time-frequency transforms areconducted to derive almost 900 statistical features as an input for machine learning algorithms. Using genetic programming,an optimized combination between feature selector and classifier is determined to detect grinding burn. The applicationof the approach results in a high classification accuracy of about 99% for the binary problem and more than 98% for themulti-class detection
