Progress in modelling and simulation of the machining process – part II: Mesh-free modelling and simulation

ABSTRACT: In this paper some rules of mesh-free/meshless modelling and numerical simulations of fundamental physical phenomena associated with the machining process, including mechanisms of plastic deformation, chip formation and interfacial friction are overviewed. Some representative examples of the mesh-free modelling application to material removal processes at different scales, i.e.: machining processes, water jet-assisted processes, additive machining processes and simulation of micromachining processes using predominantly SPH (smoothed particle hydrodynamics) method are given.

KEYWORDS: mesh-free modelling, numerical simulations, machining process

STRESZCZENIE: W artykule omówiono zasady bezsiatkowego modelowania i symulacji numerycznej podstawowych zjawisk fizycznych towarzyszących procesom obróbki, w tym mechanizmów odkształcania materiału, tworzenia wióra i tarcia. Podano przykłady zastosowania bezsiatkowego modelowania procesów obróbki ubytkowej, m.in.: obróbki skrawaniem, wysokociśnieniową strugą wody (WJM i AWJM) oraz obróbki i symulacji mikroobróbki z użyciem metody SPH (hydrodynamiki wygładzonych cząstek).
