Machining Process Monitoring System Using Audible Energy Sound Sensors

A cyber physical system for tool condition monitoring using electrical power and a mechanistic model

“…The additional power to overcome the increased friction due to tool wear (Pwear) can then be determined using equation (11).…”

“…Several sensing methods have been evaluated within the literature to determine tool wear indirectly including force [9] [10], vibration [11], spindle power [12][13] [14], acoustic emission [15], eddy current [16] or combinations of these (via sensor fusion) [17] [18] [19]. However, no research has been published focused on investigating the feasibility of monitoring the electrical power consumption of the entire CNC machine as a method of detecting tool wear.…”
