A MIMO fuzzy-control system for high-speed machining processes. Results of a case study

This paper presents a new approach to the control of cutting force in a high-speed machining process. A fuzzy-control system has been designed and implemented in an open computerised numerical control (CNC). The controller uses cutting force, which is measured from a dynamometric platform and mathematically processed by means of an integrated application, to modify the feed rate and the spindle speed in real time. The integration process, design steps and results of applying a fuzzy-control system are shown through the example of real high-speed machining operations. The results display a good transient response in the cutting-force pattern. Hence, the successful generalisation of the proposed algorithm could be one answer to the demands that industrial manufacturing makes today.
