——————————  —————————— Abstract-Simulation is now well accepted as a scientific approach to casting methoding, ensuring design process parameters, internal quality, optimal yield and short development time of casting process. Method layout involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads...

In the present study, an attempt has been made to investigate the influence of the forging parameters on cutting forces for different cutting speed, depth of cut, and feed rate during machining of Al 7075 alloy and Al 7075 alloy with short basalt fiber reinforced metal matrix composites. The experiments were conducted by using a lathe machine with tool dynamometer setup. KeywordForging effect, ...

For the development of a rotational symmetrical polyurethane part with a steel reinforcement, a requirement/constraint driven approach to process design has been taken. In this approach a scale model of the process was built using fused deposition modeling (FDM) rapid prototyping technique, then used to validate design, material and process parameters. After selection and testing on the scaled ...

OBJECTIVE Assessment of surgical outcomes of biceps tendon lengthening (BTL) surgery in obstetric brachial plexus injury (OBPI) patients with elbow flexion contractures, who had unsuccessful serial casting. BACKGROUND Serial casting and splinting have been shown to be effective in correcting elbow flexion contractures in OBPI. However, the possibilities of radial head dislocations and other c...

The objectives in this work were to develop, calibrate, and apply a model to predict ideal taper profiles down the narrow faces of the SIDERAR slab casting mold for several different casting speeds, steel grades, flux powder compositions, and widths. A significant amount of original research was undertaken for this challenging problem. A finite difference model of transient 1-D heat conduction ...

The microstructure of steel is decisive for its chemical, physical and mechanical properties. Depending on the parameters characterising liquid metal as well as the parameters of the steel casting influencing the crystallisation process, the macrostructure of casts and ingots consist of three, two or only one crystallisation zone. In steel ingots, its most frequent by consist of three zones: ch...

This article considers deterministic computer experiments with real-valued tuning parameters which determine the accuracy of the numerical algorithm. The aim is to integrate computer outputs with different tuning parameters. Finite element method with mesh density as the tuning parameter is an important case. Novel nonstationary Gaussian process models are proposed to establish a framework cons...

Scaling laws microstructural lengths derived based on simulations. The freeze casting process a novel manufacturing method both near net-shape parts as well directed porous structures employed by filters implants. Depending the choice of liq...

This study evaluated the sensitivity of an experimental model to mold temperature using a two-chamber casting machine and its recommended investment (Exp. 1), and the effect of sprue diameter and length using a one-chamber casting machine and its recommended investment (Exp. 2). Experimental patterns were cast from commercially pure titanium and percentage casting success obtained. Mold tempera...

Abstract A model is presented that predicts the amount and location of oxide inclusions in steel castings. number size distribution inclusions, defined about a mean diameter, enters casting system at its inlet during filling process are transported to their final locations casting. Model parameters for inclusion density, drag wall friction used calculate motion particles. results study effects ...
