We were able to evaluate the usefulness of DWT in detecting bearing problems early on by translating real-world information. The fundamental goal of our research was to get valuable insights into machine behavior during operation and to investigate novel techniques to monitoring and diagnostics. We have provided the groundwork for additional research and developments in the sector with this chapter, opening the way for improved maintenance procedures and improved industrial system performance.enThesis
