Using the Taguchi Method for Experimental and Numerical Investigations on the Square-Cup Deep-Drawing Process for Aluminum/Steel Laminated Sheets
The effects of input parameters on the square-cup deep-drawing process for a two-layer aluminum/steel laminated sheet were investigated. Each layer was 0.7 mm thick, and the input parameters covered in the investigation were punch nose radius (PR), die shoulder radius (DR), the clearance between a punch and die (CPD), blank holder force (BHF), and layer arrangement (LA). The effects of the inpu...
متن کاملEffect of various parameters on Wrinkling with imperfections in Deep Drawing of Cylindrical Cup
Due to limitations of finite element methods and software packages, existing in incorporating the imperfections in to the model. The parametric study of BHF, sheet thickness, die profile radius, punch profile radius, initial yield stress and sheet anisotropy and including imperfections is carried out by the model developed by Ravindra.K.Saxena [1, 2, 3]. The mathematical model is studied and va...
متن کاملNumerical and Experimental Investigation of Deep Drawing Process in Square Section of Single-Layer and Two-Layer Sheet
Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...
متن کاملLadd – Laser Assisted Deep Drawing
In the current work, cup drawing experiments with laser assistance are presented where only selected areas of the work piece have been heated up. Since the strongest deformations occur at the outer circumference of the blank, only that area has been heated up by a defocused laser beam. Selective laser heating of the work pieces was performed by diode as well as Nd:YAG laser radiation. The formi...
متن کاملApplication of Abductive Network and FEM to Predict the Optimal Blank Contour of Elliptic Cylindrical Cup in Deep Drawing
In this paper, the finite element method is employed in conjunction with the abductive network to predict the optimum blank contour of elliptic cylindrical cup with ear-less in deep drawing. The earring behavior of the formed cup is caused primarily by planar anisotropy in the sheet. Different cup heights combined with various aspect ratios of the elliptic cylindrical cup are taken into account...
