Deep Hole Drilling Machine Monitoring Systems
Machine monitoring for deep hole drilling goes far beyond counting cycles and tracking runtime. The drilling process itself generates a rich set of signals that tell you exactly what is happening at the cutting edge. I have built monitoring systems that predict tool breakage three seconds before it happens, detect material hardness changes mid-bore, and flag coolant system degradation weeks before a failure. What to Monitor Process Parameters The four signals that give the most information about the drilling process are coolant pressure, coolant flow rate, spindle power, and feed force. These four parameters, plotted against time, create a signature for every drilling cycle. ...
