Shearing, ploughing, and wear in orthogonal machining
Under normal machining conditions, cutting forces are due primarily to the bulk shearing of the workpiece material in a narrow region called the shear zone. However, under certain conditions, such as finishing cuts or a worn tool, force components due to the rubbing and ploughing of the edge or …

Determination of material constitutive models using orthogonal machining tests
… high conductivity (OFHC) copper using orthogonal machining tests. This dissertation is divided into two parts. Part one is concerned with improving Johnson-Cook (JC) constitutive model parameters for AISI 1045 carbon steel by comparing results of finite element (FE) simulations of …

ANALYSIS OF MACHINING PROCESS USING THE FINITE ELEMENT METHOD
The orthogonal machining process is modelled using the finite element method. Starting with fundamental work material properties and cutting conditions, the distribution of flow stress within the chip and workpiece is computed. Plastic and elastic tool-chip friction are accounted for. The …

A Tool Wear Comparative Study in Turning Versus Computer Simulation in 1018 Steel
<p>The material removal process uses cutting tools in order to produce the desired shape of the workpiece. Tool wear has been a problem for cutting tools, since cutting tools wear and break. Research has been accomplished in the tool wear field for tool life and more recently tool wear. The …

Modeling metal cutting processes under consideration of elastic material properties
Most machining models consider the work piece material to exhibit rigid-plastic or, when taking into account the strain rate sensitivity of the flow stress, rigid-viscoplastic behavior. This approach neglects the influence of the elastic material properties of the work piece. Another simplification …
