Publikováno v: Procedia CIRP. 102:97-102

Adequate setting of the boundary conditions for the heat equation when modeling the temperature distribution in the cutting tool is one of the key points. The boundary conditions on the tool surfaces can be divided into two groups: conditions that de

Novel metric 'Implenarity' for characterization of shape and defectiveness: The case of CFRP hole quality

Autor: Andrii Hrechuk, Jan-Eric Ståhl, V. Kryzhanivskyy, Volodymyr Bushlya

Publikováno v: Composite Structures. 265:113722

Image Processing is rapidly expanding as a technique for object and defect analysis because of the high ease of its coupling to automation and IT solutions. Yet, issues with transferability of the measurement approaches and metrics currently used in

Invariance of multifractal spectrums of spatial forms on the surface of ZnxCd1-xTe – Si heterocompositions synthesized by electron beam epitaxy and hot wall epitaxy

Autor: A.V. Morozov, P.P. Moskvin, Petro M. Lytvyn, V.A. Rudnitskyi, Liubomyr Rashkovetskyi, V. Kryzhanivskyy

Publikováno v: Journal of Crystal Growth. 475:144-149

Multifractal (MF) analysis is applied for the description of spatial nanoforms which form a relief on a surface of heterostructures of Zn x Cd 1-x Te solid solution – substrate Si (1 1 1) synthesized by the method of the electron beam with the evap

Influence of tool material and tool wear on tool temperature in hard turning reconstructed via inverse problem solution

Autor: Jan-Eric Ståhl, Oleksandr Gutnichenko, Volodymyr Bushlya, V. Kryzhanivskyy, Rachid M'Saoubi

Publikováno v: Journal of Superhard Materials; 39(3), pp 192-202 (2017)

In this work the cutting tool temperature distribution that develops during turning of hardened cold-work tool steel is modeled on the basis of experimental data. The data obtained from a series of thermocouples, placed on a PCBN insert, into an anvi

Tool–chip thermal conductance coefficient and heat flux in machining: Theory, model and experiment

Autor: R. M’ Saoubi, V. Kryzhanivskyy, Jan-Eric Ståhl, Volodymyr Bushlya

Publikováno v: International Journal of Machine Tools and Manufacture
International Journal of Machine Tools and Manufacture; 147, no 103468 (2019)

This study proposes a technique for determining a tool–chip thermal conductance coefficient and heat flux in machining. The technique is based on solving an inverse heat transfer problem (IHTP). Because the IHTP is ill-posed, a priori information i
