Method and system for controlling the operation of a cnc machine for machining a workpiece

A non-transitory computer-readable medium encoded with executable instructions that, when executed, cause one or more data processing systems to execute a method for controlling the operation of a CNC machine for machining a workpiece, the method comprising:

• a) during a learning phase, machining the workpiece without adaptive control under regular cutting conditions, thereby learning power and vibration patterns of the workpiece for different tools and building power consumption and surface roughness models for each cutting operation of the machining process;
• b) based on the models and a predefined optimization strategy, calculating objective function values and constraints to be implemented by an adaptive control function;
• c) in an operational stage, machining the workpiece with the adaptive control function and modifying cutting conditions, including a cutting feed and a spindle speed, in real time to achieve the calculated objective function values while maintaining the constraints.
