Investigation of the Forming Force in Torsion Extrusion Process of Aluminum Alloy 1050

In this paper, torsion extrusion (TE) process on 1050 aluminum alloy was investigated by simulation as a severe plastic deformation (SPD) method and the effects of friction coefficient, angular velocity of the rotating die and punch speed on maximum punch force were studied. A finite element (FE) model was developed to simulate the TE process via DEFORM software. The FE results were validated co...

Development of a Spiral Trajectory for High Speed Roughing of Light Alloy Aerospace Components

A new spiral cutting method and its implementation within a CAD/CAM application software is proposed to save more than 16% in the roughing process of pockets for light alloy aerospace parts. The application prototype developed automatically generates the tool paths related to specific pocket profile geometry. It is shown, through experimentation using the prototype, that the parameters which de...

Research on Three-point Centering Device of Cylindrical Drill Pipe

In the process of tightening up and screwing off the iron roughneck, it is required that the center of clamping pliers and the center of drill pipe are coincident, so as to avoid the damage of the circular guide in clamping system, and to ensure the iron roughneck work normally. While the traditional method of centering is artificial in iron roughneck, its precision is low, so it is easy to dam...

A Taguchi approach on optimal process control parameters for HDPE pipe extrusion process

High-density polyethylene (HDPE) pipes find versatile applicability for transportation of water, sewage and slurry from one place to another. Hence, these pipes undergo tremendous pressure by the fluid carried. The present work entails the optimization of the withstanding pressure of the HDPE pipes using Taguchi technique. The traditional heuristic methodology stresses on a trial and error appr...

Fabrication of Spiral Stent with Superelastic/ Shape Memory Nitinol Alloy for Femoral Vessel

Stent is a metal mesh tube for opening the obstructed vessels of the body. Ni-Ti alloy is a suitable metal for fabrication of stent due to its potential for applying the appropriate stress and strain to the vessel walls. In this study, super-elastic Nitinol wire was used to build stent samples usable to open femoral vessel. Ageing was performed at 500°C for different periods of time to determin...
