Cold forging is often applied in the fastener industry. Wires in coil form are used as semi-finished products for the production of billets. This process usually requires preliminarily drawing wire coil in order to reduce the diameter of products. The wire usually has to be annealed to improve its cold formability. The quality of spheroidizing annealed wire affects the forming quality of screws...

Esref is a congenitally totally blind man, practiced in drawing. He was asked to draw solid and wire cubes situated in several places around his vantage point. He used foreshortening of receding sides and convergence of obliques, in approximate one-point perspective. We note that haptics provides information about the direction of objects--the basis of perspective.

In this paper, unique tests into the production of galvanised steel wires in industrial conditions were presented. It was demonstrated that three phenomena occur during wire-drawing process at high speeds: namely, zinc sticking to surface drawing drums, coating grinding caused by a larger friction area between tool and material, combined with detachment calibrating part die until wire breaks is...

An efficient and environmental-friendly method, featuring a cyanide-free plating process was established for Au-coated Ag wire (ACA). This new Ag wires can meet the reliability standards of wire bonding. The proposed ACA wire was studied to ensure compatibility with electrical properties; mechanical properties and free air ball characterization. Tensile tests showed that ACAwire was stronger th...

Objective: To compare outcome of patients with supracondylar fractures of humerus treated by cross K-wires and lateral entry K-wires in children. Patients and methods: It is a randomized controlled trial study, conducted at Department of Orthopedic surgery, Shaikh Zayed Hospital/PGMI Lahore, during period of 8 months (June 2011 to Feb. 2012). Total 200 cases were included in the study (divided ...

Modernization of mechanical industry has lead to the increase in demand for hard and tough materials and thus various non traditional methods have been developed in order to machine such hard and tough materials. Wire Electric discharge machine is one of the most commonly used machine which is employed in machining of conductive metals of any hardness or that are difficult or impossible to cut ...
