CNC Machine

CNC appear to be some of the most "predictive maintenance friendly" type of machine as they mainly produce huge amount of data and are at the same time high precision systems which are sensitive to wear and configuration changes. But the main issue is that a CNC machine is a mix of different components which each undergoes wear and damage that can affect other (more critical) components. So to predict failure on critical components of a CNC is important to create model that can understand links between components and how they can impact one another : for example dissociates a tool wear with the spindle wear on machining center when we only got vibration/current data on the spindle (what is the case most of the time).
