Real-Time Tool Wear Monitoring Eliminates Downtime and Cuts Tooling Costs by 50%

Industry: Firearms Manufacturing
Machine: Horizontal Lathe
Material: Hardened 4140 Steel
Tooling: 1/2" 5 Flute End Mill


This customer, machining high-volume firearm safety levers, was experiencing costly collet replacement and downtime due to operators running tools to their breaking point. They were making decisions based on tool life guestimates and time in cut.


The customer implemented Caron Engineering’s adaptive tool monitoring system, TMAC.

TMAC calculates the power consumed over the duration of the cut to calculate tool wear. As tools wear, TMAC is calculating this in real-time, and the measured wear is easily viewed by the shading of the monitored cut. If a tool reaches the wear percentage (limit), TMAC finishes the cut and expires the tool. If a tool breaks, TMAC stops the machine and retracts the tooling before damage can occur.

By assessing tool wear prior to a tool breaking, this customer has dialed in their wear limit parameters so well that the tool is safely pushed to a point of real tool wear without going over the edge and breaking. This allows the customer to get the maximum life out of the tool. They have the work wear limit set at 95% to retire the tool. Beyond that, the likelihood of breaking is extremely high.


  • 50% reduction in tooling costs
  • Eliminated damage and downtime from tool breakage
