Abstract

The present invention discloses a method and a system for controlling the operation of a CNC machine for machining a workpiece, said method comprising: a) during a learning stage machining the workpiece without adaptive control under regular cutting conditions, thereby learning the 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; b) based on the created models and a predefined optimization strategy, calculating objective function values and constrains to be implemented by an adaptive control function; c) at an operation stage machining the workpiece with the adaptive control function thereby modifying the cutting conditions, such as cutting feed and spindle speed, in real time to achieve the calculated objective function values while maintaining the constrains. After each workpiece the power consumption and surface roughness models objective function values are corrected based on collected data.
