Adaptive Feedrate is the closed loop control of the machines feedrate and automatic adjustment based on feedback from the process.
Once you program the normal load level for an operation, if the load increases, the feed rate reduces to bring the load back to the normal level. If the load reduces, the feed rate increases.
Adaptive Feedrate optimises the cycle time of a process by closing the loop on dynamic process parameters, for E.g. Spindle Load, increasing a machines production and output.
Close loop means the process is monitored and adjustments are made dynamically. A machine can be automatically optimised without the need of having an operator present. The closed loop process also produces more consistent and higher quality output which also helps to extend the life of the machines wheel.
