I apologize up front for my ignorance and hope that I'm not imposing on your generosity.
I need to measure the change in down-feed force required to make a z-axis cut on a CNC milling machine to test drill bit wear. The down-feed is driven by a servo motor. As the drill bit gets dull, more down-force is required. Is there a way to monitor the servo's load to get a relative wear comparison for different drills and/or metals being drilled?
I thank you in advance.
