PRINCIPLES OF CONCEPTUAL APPROACH TO CREATING TOOL SUBSYSTEM FOR MULTIOPERATION MACHINE SMART-PASSPORT

The basic principles of the construction and operation of the machine monitoring system in the computer-integrated manufacturing are described. The tool condition and the tooling backup control are the focus of attention. The proposed approach is aimed at creating conditions for the effective functioning, and the tool state management using a knowledge system of TOOL unit of the machine Smart-passport. The unit architecture is presented by a set of modules including a data acquisition module, a module for observing changes in the tool state and control, a monitoring module, and others. The significant innovation of the research is the introduction of the concepts of fuzzy boundary and border lines of sizing wear, and of overall tool life based on the theory of fuzzy knowledge concepts. The introduction of these concepts is related to the necessity to adapt modes of cutting and decision making depending on the tool state and its effect on the part accuracy.
