Cyber-Physical Machining Systems Based on Commercial CNC Equipment

The article addresses the problem of building cyber-physical control systems of metal machining based on commercial computer numerical machine control systems (CNC). The article provides an overview of possibilities of integrating third-party software into common CNC units. The analysis has revealed a universal way of integration and resulted in a diagram of the cyber-physical machining system based on the CNC OSP-P300L with hardware and algorithmic support to be selected and validated. As an algorithmic support, there has been proposed a test run method based on measuring the thermoEMF value that is an integral companion of the cutting process and carries information about the conditions of its behaviour. This method supported by linear programming algorithms makes it possible to set optimal cutting modes with respect to the pre-selected criteria directly in processing. Programmable logic controllers have been proposed to be used as hardware because they are the most flexible option in configuration and upgrading.
