Popis:	Summary A kinematic model of single edge cutting action in grinding has been developed. The model describes the force pulse created by chip formation at the cutting edge. This pulse is assumed to excite acoustic emission (AE) signals. The typical values of its features (risetime, width, amplitude) determine the requirements for the measurement equipment. AE was measured on the workpiece during grinding and was analysed in the frequency range between 70 kHz and 3.5 MHz. A suitable signal analysis strategy was developed to extract meaningful information from the AE signal using frequency domain feature extraction. The comparison of model and measurement output allows the identification of model parameters. The parameter values give a description of the grinding wheel state and the process state.
