Abstract

The article presents the association of the output signals of the grinding process with the machining parameters. The article focuses on assessing the suitability of grinding force signal and acoustic signal acquisition for different process conditions. In the first part of the article the kinematic contact of abrasive grain with the workpiece analysis was carried out. By analogy to the micro-cutting process, geometric analyses are presented and the process parameters that have a major impact on the grinding zone load are indicated. Analytically it has been shown that elementary grinding speeds (wheel and workpiece speed) and grinding depth have a significant effect on recorded signal values. The work also presents a set of factors and phenomena that are sources of acoustic emission impulses in the grinding process. For a selected range of grinding parameters, an experimental verification was performed. The article presents the highly correlated relationship between grain penetration depth (maximum uncut chip thickness) and grinding force components, as well as the effective value of acoustic emission. The output signals of the grinding process were also compared, indicating the advantage of the acoustic emission signal above the grinding force in terms of the reaction speed (and lag) of the sensors to the phenomena occurring in the grinding zone.

Paweł Sutowski received his MSc degree in Mechanics and Machine Design and PhD (with honors) degree in Machinery Construction and Operation from Koszalin University of Technology, in 2001 and 2008, respectively. Since 2008 he has didactic-research position in the Department of Production Engineering at the Koszalin University of Technology, where currently he works as an Assistant Professor in production planning and control team. His scientific work focus on problems concerning quality and efficiency control of machining processes by monitoring and diagnostic output signals. In his work, he uses modern signal acquire and converting unit systems. The most important in his work are non-destructive testing (NDT) methods with the use of acoustic signal and others. He has participated in national research projects, presenting results of his work at international and national conferences. He has published scientific papers in international and national journals, book chapters, as well as conference proceedings. He is also the co-author of one monograph. In his professional work he was also experience in domestic and foreign industry. He was a CAD designer (Satrorius AG in Germany, GIPO Corp. in Denmark and Poland), as well as software programmer and commercialize (ZETO S.A. in Poland)
