Abstract

System approach is widely used in modernization of business-processes, organizational structure, corporate documentation procedure and economical information systems. The application of methods of system analysis when introducing the results of engineering research is not covered sufficiently today, that is why the aspects of work related to the application of IDEFO notation to the description of the system being worked out upon the results of scientific researches in the field of metal cutting is important now.

The work covers the application of methods of system analysis when assimilating the results of researches of assessment of metal cutting tool wear rate using the acoustic emission of cutting process. The authors used the analysis of processes in IDEFO notation to describe the developed information system for material machinability estimation. 

The authors developed the context diagram containing the external interactions of the analyzed system. The internal interactions of the analyzed system at the high decomposition level are displayed on the diagram of decomposition of the first level. The authors carried out the structuring of system functions and necessary for system functioning resources within the frames of input, output, supporting and regulating parameters of the processes. The article offers the methods of assessment of machinability based on the use of visual and numeric representations of the information and the application of modern technologies of semi-structured information processing. 

The results of the research showed that the use of the process analysis according to the IDEFO methodology is the effective tool allowing at the stage of the research results implementation to structure the information interactions within the frames of input, output, supporting and regulating parameters of the processes at different levels of the system detailing. The application of the system analysis methods to the description of the system for machinability assessment using the acoustic emission signal allowed identifying the basic requirements to the information system which specialization is possible within the frames of accepted methodology when moving to the lowest levels of decomposition in the system processes description.
