ABSTRACT: In this article, several possibilities for integrating AI methods with FEM-based modelling for coefficient of friction (COF) prediction are reviewed and discussed. In particular, the implementation of a Grey-Box model and selected regression testing methods is presented. Results of integrating a Python interface with the FEM DEFORM package for predicting componential cutting forces and cutting temperatures using estimated COF values are provided. The performance of different friction models implemented in FEM and SPH simulation packages is compared. New trends and future research directions are also outlined.

KEYWORDS: artificial intelligence, FEM modeling, coefficient of friction (COF), Grey-Box model, friction models, cutting forces and temperature

STRESZCZENIE: W artykule omówiono możliwości integracji metod sztucznej inteligencji (AI) z modelowaniem metodą elementów skończonych (FEM) do prognozowania wartości współczynnika tarcia. W szczególności przedyskutowano zastosowanie tzw. modelu szarej skrzynki (Grey-Box) i kilku metod testowania regresyjnego, a podano wyniki integracji interfejsu Pythona z programem symulacyjnym DEFORM dotyczące sił skrawania i temperatury, wykorzystujące wyniki prognozy współczynnika tarcia. Porównano efekty zastosowania różnych modeli tarcia w metodach FEM i SPH. Omówiono przyszłościowe kierunki badań.

SŁOWA KLUCZOWE: sztuczna inteligencja, modelowanie MES (FEM), współczynnik tarcia (COF), model szarej skrzynki, modele tarcia, siły tnące i temperatura skrawania
