“…Residual stresses were determined by the ultrasonic acoustic strain measurement [30,31]. This method consists in the analysis of the change in the velocity of ultrasonic waves resulting from the presence of residual mechanical stresses on the surface of the experimental sample (Fig.…”

“…The time delay of the signal introduced by a special time delay unit 6, which is triggered by a pulse coming from the generator 7 and generates (by the unit 5) a rectangular pulse of duration τ 0 . The technique of the study is to measure the velocity of the pulse in the stress-free sample and in the sample with the cutting-induced residual stress [31,32]. This velocity difference allows for determining residual stress according to formula (47).…”

Product Lifecycle Management (PLM) system requires consideration and ensuring efficient operating conditions for the most loaded parts in the product, not only at the product's design stage, but also at the production stage. Operational properties of the product can be significantly improved if we take into consideration the formation of the functional surfaces wear resistance parameters already at the planning stage of the technological process structure and parameters of the product's machining. The method of constructing predictive models of the influence of the technological process structure on the formation of a complex of product's operational properties is described in the article. The relative index of operational wear resistance of the machined surface, which is characterized by the use of different variants of the structure and parameters of this surface treatment, depends on the microtopographic state of the surface layer and the presence of cutting-induced residual stress. On the example of the eject pin machining it has been shown how the change in the structure of the manufacturing process from grinding to the turning by tool with the tungsten carbide insert affects the predicted wear resistance of the machined functional surface.

“…The modern software DEFORM-2D (Scientific Forming Technologies Corp.) was used for predictive research of the machining process [19]. This system is a multi-purpose FEM analysis program, which is designed to solve two-and threedimensional dynamic nonlinear problems of the mechanics of a solid body deformation, as well as problems related to this process.…”

The article describes how different friction coefficients under certain cutting conditions and parameters affect the formation of the stress-strain and thermal states of the product when titanium alloy machining. A new research methodology is used for the study. Firstly, in the initial data for simulation, each time a different declared coefficient of friction is proposed, and every such task of the cutting process modelling is solved for various cutting parameters. The second stage analyzes how these coefficients influence the stress-strain and thermodynamic state of the workpiece and tool during cutting, as well as the tool wear dynamics. In the third stage of the study, ways for ensuring these analytically-grounded tribological cutting conditions are proposed. The analysis of different wear criteria in the simulation models of titanium alloys cutting is carried out. Experimental studies confirm simulation results.
