Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

E ctopic eruption of the permanent first molar is a local eruption disturbance in the developing permanent dentition. This abnormal eruption pattern is most commonly seen in the maxillary arch. The abnormal mesioangular eruption path of the maxillary first molar causes resorption of the distal root of the adjacent primary second molar. Progression of ectopic eruption may cause impacted permanen...

This study was designed to explore a new method for the assessment of dental crowding from study models, which would be both valid and reproducible. This was then tested against two previously reported strategies. A single examiner compared the following methods: visual examination, brass wire/callipers, and a reflex microscope with its customized computer program. Sixty study models (30 maxill...

WEDM process is used extensively where the conventional machining process shows their limitations. Wire Electrical Discharge Machining is used to manufacture geometrically intricate shapes with higher accuracy and better surface finish. In the present study, the performance parameters i.e. cutting speed and surface roughness were investigated. The experiments were conducted under the constant c...

The disposal of scrap rubber, represented by retired tires, has achieved industrial achievements, but the handling brass-coated steel wire as a structural reinforcement in tires received little attention. A feasible and efficient method acquiring economical resources is proposed to extract copper zinc (Cu-Zn) from wire. With 20% ammonia, 10% hydrogen peroxide, liquid-solid ratio 10, brass coati...

Wire electric discharge machine (WEDM) is spark erosion in unconventional machining technique to cut hard and the conductive material with a wire as an electrode. The blanking die material SKD 11 is a high carbon and high chromium tool steel with high hardness and high wearing resistance property. This tool steel has broad application in press tools and dies making industries. In this research ...

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 ...

Wire electric discharge machining (WEDM) is one amongst the unconventional processes which might cut all kinds of shapes with an accuracy +/?0.001mm. It will materials that conduct electricity and can even exotic metals like tungsten carbide, Hastelloy, Inconel etc. In present work, on 600 by wire EDM cryogenically treated brass performed. Brass 0.25mm diameter has been at ?90 ° C, ?100 C ?110 ...
