Methods and systems for adapting a feed rate of a feed control on numerically controlled machine tools

A computer-implemented method for providing setpoint values for a feed rate for adaptive feed control on numerically controlled machine tools, the method comprising machining a workpiece with a tool, and during the machining:

• receiving a real-time data associated with a current state of at least one controlled axis, wherein the real-time data comprises measured values of a torque of a spindle;
• determining actual values of at least one cutting force of the tool from the torque of the spindle;
• receiving a look-ahead data associated with a predicted state of the at least one controlled axis;
• simulating the machining of the workpiece based on the real-time data and on the look-ahead data, wherein simulated values of the at least one cutting force of the tool are generated, the simulated values comprising values of the at least one cutting force of the tool predicted in time increments, which are sufficient to adjust the feed rate before a force spike occurs;
• determining at least one setpoint value for the feed rate of the at least one controlled axis based on the simulated values and on the actual values of the at least one cutting force of the tool;
• and
• providing the at least one setpoint value for the feed rate of the at least one controlled axis.
