Abstract

The main tasks of the theory of metal cutting in the traditional scientific view of the mechanisms and patterns of tool wear in the operation of edge cutting machining are viewed. It is shown that the need for continuous expansion of the field of interests of specialists is derived from the improvement of construction and tool materials as well as blade tools structure. It is caused by the expanding spread of hard-alloy tools having multilayer wear-resistant coatings, structural materials with increased physical, mechanical and special operation characteristics. Exclusive standards for the stability of machining operations resulted from the gain in specific weight of expensive CNC equipment in the total mass of production tooling for machining industries. The customization of machine-building production and functional requirement toughening for the manufactured products specifies reliability growth for the results of machining. The factor determining the «vector of attention» change regarding metal cutting science should take into account the expansion of information technologies influence and, in particular, the development of artificial intelligence systems. It is shown that the existing means of digitalization can significantly increase the efficiency of machining production due to the developed means of mathematical modeling and forecasting of processing results. An additional mechanism for ensuring the stability and reliability of metalworking should be considered as the transition from monitoring systems of the technological system element state to adaptive control systems with a feedback. The possibility of adapting cutting conditions to the «instantaneous» state of the elements of the technological system is proved, taking into account the stochastic nature and a variability of the properties of the contact pair «tool – material blank». Thus, digitalization and intellectualization of production determine the transformation of views on the subject as well as metal cutting techniques.
