Finite Element Modeling for Orthogonal Cutting Process 2015-36-0356
Nowadays the industries are using in large-scale the modeling of components by the finite element method to predict and anticipate events with the control variables of a project, such as, forces, displacements, moments, stress, etc.
In machining processes, the control of these variables makes the process more stable and effective, therefore the use of CAE tools promotes better control of time and costs in the process.
The CAE tools are designed to derive a computational model to predict strain, stresses and the forces on the work-piece, as well as the load on the cutting tool according to specific machining parameters, such as cutting speed, tool advance, machined material, tool geometry and others.
This paper covers the use of the finite element method to simulate the machining process by orthogonal cutting using the explicit method and based on Johnson-Cook formulation for the material behavior, when the work-piece is subjected to high strain and heat generation during the machining processes. In that way, it is considered that heat is transferred through Conduction between Cutting tool and work piece. This study aims to determine the cutting force during the machining process, which is a control variable for the process.
