Термомеханічні та трибологічні аспекти різання багатошарових пакетів «вуглеп-ластик–титановий сплав»

Drilling of CFRP-titanium alloy stacks is a complex technological task due to significant differences in the physical, mechanical, and thermophysical properties of carbon fiber and titanium alloy. This article presents a review of modern scientific research describing the physics of the cutting process separately for each layer of the package and comprehensively for transient processes in the contact zone of carbon fiber and titanium alloy, respectively. The features of the fracture mechanisms in the cutting zone for each of the stack materials are analyzed, and a classification of factors affecting the wear conditions and growth during the drilling process is performed. It was determined that the combination of the abrasive effect of carbon fibers significantly worsens the microgeometry and microrelief of the cutting edge, creating favorable conditions for the adhesion of titanium alloy particles to the tool surface. The combination of adhesive and abrasive wear processes significantly reduces the tool life, complicating the possibility of a thorough study of this phenomenon.
