Features of the manufacturing technology of a multilayer tool with an ordered texture

Abstract

The auto-oscillatory process in metal cutting is analysed in order to understand the nature of chip formation in turning and to evaluate the importance of ensuring the stability of the technological system in machining. The method of multilayer tooling with ordered texture is selected as one of the promising directions for solving this problem. Microfractographic analysis is carried out on fractures of specimens cut in transverse and longitudinal directions. The character of crack propagation at fracture by the ductile intragrain mechanism is established. The design of a holder of a penetrating cutter with inserts having a directed texture is proposed on the basis of studies of a multilayer tool with an ordered texture.
