Abstract

Due of the need of reliable methods to indicate a proper dressing, and the need to prevent the consequences of excessive wear in dressers, this research aims at assessing the changes in the structural health of the single point dresser and multipoint dresser caused by the wear, during its lifetime or damage and failure caused by other factors, such as temperature or shocks. The approach is to employ the fundamentals of damage detection based on the electromechanical impedance (EMI) commonly used in structural health monitoring for monitoring the dressing operation. The impedance method is characterized by its flexibility of using low-cost piezoelectric transducers, such as ceramics of Lead Zirconate Titanate (PZT), in structural damage detection. In this sense, research has been conducted in the Transducers and Data Acquisition Laboratory, coordinated by Professor Fabricio Guimarães Baptista, related to the project funded by the Sao Paulo State Foundation (FAPESP) (2015 / 02500-6) entitled "Monitoring Systems Based on Electromechanical Impedance Technical: New Trends and Challenges ". In addition, results of recent research in the Grinding Process Laboratory, coordinated by Professor Paulo Roberto de Aguiar, shows that the low-cost PZT transducer has great potential in monitoring the grinding process. Hence, this research aims to approach theoretically a new way of monitoring the dressing operation with specific regard to the wear of single-point dressers and fault detection and multipoint dressers by using impedance correlations measured through the EMI method. Consequently, this work will contribute to a new technology for monitoring the dressing operation and optimizing the grinding process.
