FE-Modeling of Cold Rolling by In-Feed Method of Circular Grooves

Abstract

The methods of cold rolling of rods are widely used in manufacturing industries to obtain pieces with complex profiles. In this study, complex profiles with grooves have been formed by in-feed methods using two rolls. An experimental system was constructed to record the process parameters. The microhardness has been measured by the Vickers method in an axial section of the rolled piece. The process has also been simulated by means of finite element calculations using the Abaqus/Explicit code. The material behavior is described by using a 5-parameter strain-hardening law and by accounting for thermal effects at high strain-rates. Finally, a comparison is made between experimental and simulated results.

Superplastic Forming of a Three-Stage Hemispherical 5083 Aluminium Profile

“…It is a superior technique for causing large amounts of deformation under low strain rates and flow stresses, in comparison with techniques such as deep drawing [1] and [2], hot rolling [3], cold rolling [4], incremental forming [2], [5] and [6] and other heat treatment processes [7].…”

Numerical Analysis of Rectangular Groove Cutting with Different RC Tools

“…A validation finite element simulation which showed satisfactory results was conducted with obtained optimum tool geometry. In Niţu's research [15], a FE simulation of the cold rolling process by using an optimized FE mesh and the stress-strain law is performed. The results show that valuable information could be obtained from FE simulations.…”

“…Based on the universal slip-line model, Jawahir et al developed new analytical models to predict chip back-flow angle [8], tool-chip interface friction and chip-groove effects [9] in machining with RC tools. In recent years, the Finite Element Method (FEM) has been gaining importance as a tool to predict cutting performance [10][11][12][13][14][15][16][17]. FEM has been used to investigate effects of friction in cutting, shear stress on the chip-tool interface, burr formation, temperature distribution on cutting zone etc.…”

Modelling and control of tinning line entry section using neural networks

“…In real operational conditions, complex dynamic systems, such as the technological line for rolled steel strip treatment described below, can be in various different states. Using simulation we can then experiment with the line model similarly to the real system, without the need to intervene in the real system, eliminating the risk of possible emergency states [1][2][3][4].…”
