Micro-milling is a precision milling technology where the cutting parameters are in micro scale. It has been increasingly applied to modern industry, from aerospace to bioengineering. Tool condition monitoring (TCM) in micro milling poses new challenges compared to conventional CNC machining, due to the high tool wear rate and high precision requirement associated with the features at micro-level. In this book, a generic noise-robust system is developed for the micro-milling tool condition monitoring. Mathematical tools such wavelet analysis and independent component analysis (ICA) have been...
