Abstract: A method, system, and apparatus for an adaptive controller for controlling a machining operation on a workpiece by a machining tool are provided. The system includes a sensor for measuring a present value of a spindle load on a spindle drive, and an adaptive controller for comparing the present value of the spindle load to a present value of a target spindle load. The adaptive controller includes a computing element configured to determine a first feed rate value of a machining tool, and a number generator configured to generate a first feed rate dither adjustment value used for adding noise to the first feed rate value. The adaptive controller is configured to control the feed rate of the machining tool relative to the workpiece to maintain the present value of the spindle load approximately equal to the present value of the target spindle load using one or more of the first feed rate value, the first feed rate dither adjustment value, and the second feed rate dither adjustment value.

Abstract: A method and system for a machine tool system are provided. The system includes a spindle, one or more sensor devices configured to determine a value of an operating parameter of the system, and a software application embedded within a control program of the machine tool system. The software application includes a process controller integration module configured to receive the determined operating parameter value from the sensor device, compare the operating parameter value to a predetermined allowable range, and generate one or more alerts using the comparison. The software application also includes a GUI interface module configured to display the alerts in at least one of a graphical and a textual form on a display of the machine tool system. The GUI interface module is further configured to communicate user inputs to the process controller integration module and receive information for user displays from the process controller integration module.
