Diagnostics and monitoring of complex production processes using measurement of vibration-acoustic signals

A vibration-acoustic method for diagnostics and monitoring of production processes such as cutting metals makes it possible compared with other methods to reduce the requirement for measuring equipment and it provides a computer representation of the results observed. The set of equipment suggested has low cost and it exhibits considerable flexibility compared with existing equipment. __________ Translated from Izmeritel’naya Tekhnika, No. 7, pp. 30–34, July, 2006.     

Effect of adhesion bonds in friction contact on vibroacoustic signal and autooscillations

Autooscillatory phenomena often accompany friction and cutting processes and have many similar features for them. The paper proposes a phenomenological model, which relates the energy of triboacoustic phenomena with the specific features of dry friction modes occurring in movable joints and during the cutting of materials. This work is aimed at expanding the application of vibroacoustic diagnostic systems to engineering equipment in friction and metal cutting.     

Monitoring of electric discharge machining by means of acoustic emission

Electric discharge machining is accompanied by acoustic-emission signals, which may be used monitoring, diagnostics, and control of the process. Experiments show that the acoustic signals permit assessment of the efficiency of the current pulses supplied and optimal technological adjustment.
