Adaptive control of feed rate helps avoid crashes by slowing down or stopping the feed of an CNC program when the spindle is overloaded. The load of a DMM DYN4 servo drive and DMM 750W servo are monitored by a custom LinuxCNC module that instructs LinuxCNC to adjust the feed rate to keep the spindle load below a set point.

This idea is not new, and was included in a 1968 report from Bendix as part of a USAF contract.
