MultiCam LP (Dallas/Ft. Worth Airport, Texas) has introduced Automatic Dull Tool Detection capabilities to its line of routers. The added technology enables users to optimize tool life and change tools in the middle of a job, without the need to scrap the part and restart. The system works by allowing the user to set a high current limit when setting the normal current draw on a new tool. As the tool wears (drag due to friction increases), the current draw will increase. When the high limit is reached, production continues for a preset time, but then the machine pauses and prompts the user to change the tool. The user may opt to override the limit and finish the job before changing the tool, or change the tool, recalibrate, and then "Prox Restart" the job, taking advantage of the system's built-in ability to maneuver the cutting head back to the point where the job was paused and resume cutting.
