Experimental Study of the Effect of Laser-Cutting Process Parameters on Heat Distribution and Cutting Edge Quality of Steel Sheets
This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...
متن کاملOn the separation criteria in the simulation of orthogonal metal cutting using the finite element method
This paper aims to gain an understanding of the reliability of the existing separation criteria for orthogonal metal cutting. To focus on their physical inherence, a simple finite element model under plane-strain deformation was used to investigate the mechanics of cutting from the incipient stage. The workpiece materials studied were elastic–perfectly plastic and elastic–plastic with work hard...
متن کاملAn Explicit Finite Element Model to Study the Influence of Friction during Orthogonal Metal Cutting
* Corresponding author – [email protected] Tel: 414-229-4126 Fax:414-229-6958 ABSTRACT Understanding the tribological aspects of machining processes is essential for increasing the dimensional accuracy and surface integrity of products. In the present investigation, orthogonal metal cutting simulations were performed using an explicit finite-element code, LS-DYNA. In the simulations, a rigid stee...
متن کاملFinite Element Simulations of Ti6Al4V Titanium Alloy Machining to Assess Material Model Parameters of the Johnson-Cook Constitutive Equation
The machining of titanium alloys poses several inherent difficulties owing to their unique mechanical properties and cutting characteristics. Finite element (FE) simulations have reduced the burden of extensive experimental trials in understanding the deformation behavior and optimize the cutting process. The FE code relies on the qualitative nature of inputs such as material flow stress model,...
متن کاملChip Formation Process using Finite Element Simulation “Influence of Cutting Speed Variation”
The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...
