This paper describes the work done between IUST and two Iranian steelworks to evaluate and review the performance of mould fluxes in current use for continuous casting. Calculations have been performed to compare actual values of powder consumption, viscosity and break temperature of the fluxes in current use with required values derived from published empirical rules for casting conditions....

The sintering temperature and holding time have a significant impact on the densification of ceramic compact. In this study, alumina inserts were made with varying temperatures times. procedure began compacting powders inside mould trapezium round shapes. These then sintered between 1200 °C 1400 for 5 to 9 h time. samples underwent analysis based shrinkage size, density, microstructure. sample ...

Cylindrical microlens array (CMA) is applied widely in imaging, sensing, and laser machining fields. Among the many techniques for CMA, moulding considered a mass-production method with low-cost good accuracy. Aimed at present problems of CMA moulds, which include low processing efficiency prediction surface topography, this paper focused on fabrication RB-SiC moulds by precision grinding micro...

We demonstrate a new tool for integrating microfluidic channels with commonly used electronic probing techniques. The "microfluidic probe" allows rapid and repeatable fluidic and electronic addressing of small die sites on a variety of substrate types without the need for permanent modification or dicing of the device wafers. We also use the probe to demonstrate locally patterned chemical modif...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...

In order to improve the optimal performance of a machining process, a booster to improve the serve control system performance with high stability for EDM is needed. According to precise movement of machining process using electrical discharge (EMD), adaptive control is proposed as a major option for accuracy and performance improvement. This article is done to design adaptive controller based o...

the electro discharge machining (edm), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. in this study, effect of ...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

Traditional environmental mould analysis is based on microscopic observations and counting of mould structures collected from the air on a sticky surface or culturing of moulds on growth media for identification and quantification. These approaches have significant limitations. A DNA-based method of mould analysis called mould specific quantitative PCR (MSQPCR) was created for more than 100 mou...

This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...
