EXPERIMENTAL EVALUATION OF DRAW BEAD COEFFICIENT OF FRICTION

Acta Metallurgica Slovaca, 2017
In this paper the results of both friction coefficient and springback testing using a drawbead test are presented. Deep drawing quality steel sheet (DC04 according to EN 10130:2009 standard) was used as the test material.

Electrohydraulic sheet metal forming with flexible tools

MATEC Web of Conferences, 2018
In cold metal forming usually a die and a punch are required to form sheet metal in the desired shape. These two parts of the tool need to be produced of hardened materials in high precision.

Forming Of Spherical Titanium Cups From Circular Blanks With Cutouts On The Perimeter

Archives of Metallurgy and Materials, 2015
Despite substantial demand for drawn parts made of high-strength sheet metal (including titanium alloys) observed in the modern industry, particularly automotive and aviation, their application remains insignificant.

Thickness control in a new flexible hybrid incremental sheet forming process [PDF]

, 2017
Incremental sheet forming is a cost-effective process for rapid manufacturing of sheet metal products. However, incremental sheet forming also has some limitations such as severe sheet thinning and long processing time.

The Effects Of Friction On Stamping Process Of Sheet Metals Used In Aviation

Archives of Metallurgy and Materials, 2015
An important factor in the possibility of obtaining correct drawn parts with the desired functional properties is the friction between the stamped sheet and the tool.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

A New Approach for Obtaining the Compression Behavior of Anisotropic Sheet Metals Applicable to a Wide Range of Test Conditions

Metals, 2020
The consideration of anisotropic and asymmetric tension-compression behaviour in some materials has proved to be of great importance for the modelling of plastic behaviours that allow for accurate results in sheet metal forming analysis.

The Use of Non-Edible Green Oils to Lubricate DC04 Steel Sheets in Sheet Metal Forming Process

Lubricants, 2022
Lubrication is a basic and relatively effective way to reduce friction in sheet metal forming operations. The drive to eliminate synthetic and mineral oils, which are difficult to recycle, from the manufacturing process has opened up opportunities for ...

Characteristics of micro incremental in-plane bending of sheet metal using tiltable punch [PDF]

, 2013
Incremental forming methods have gained interest in recent years as a forming technique for micro and fine components. This paper presents a newly developed incremental in-plane bending with tiltable punch for micro-metal sheets whose thickness is less ...
