Open Architecture Software Design for Online Spindle Health Monitoring

This paper presents an open systems architecture-based software design for an online spindle health monitoring system. The software is implemented using the graphical programming language of LabVIEW, and presents the spindle health status in two types of windows: simplified spindle condition display and warning window for standard machine operators (operator window) and advanced diagnosis window for machine experts (expert window). The capability of effective and efficient spindle defect detection and localization has been realized using the analytic wavelet-based envelope spectrum algorithm. The software provides a user-friendly human-machine interface and contributes directly to the development of a new generation of smart machine tools.
