Tool Wear Monitoring in Deep Hole Drilling: Spindle Load, Acoustic Emission, and What I Actually Use
I have broken more gun drills than I care to count. Every one of those breakages happened inside the hole where I could not see it coming. That is what drove me to build a real monitoring strategy — not just watching a spindle load bar on the control, but layering multiple signals so I catch wear, chip packing, and material anomalies before they snap the tool. Here is what I have settled on after years of testing different approaches. ...
