High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

Advancements in technology enhances not only human comforts but also damages the environment. Use of metals as containers has become popular and safe now, especially to carry the liquids. Inspite of the inherent advantages and disadvantages existent in its disposal. Today the construction industry is in need of finding cost effective materials for increasing the strength of concrete structures....

We have researched several new focused ion beam (FIB) micro-fabrication techniques that offer control of feature shape and the ability to accurately define features onto nonplanar substrates. These FIB-based processes are considered useful for prototyping, reverse engineering, and small-lot manufacturing. Ion beam-based techniques have been developed for defining features in miniature, nonplana...

Commercial agricultural machines are noted for having some limitations in their functions, which motivates the proponents to develop and apply new ideas applications. This innovative machine can clean pollen grains by operating cleaning cylinder at moderate speeds. A hook-on wood lathe assembly is provided effecting attractive soft broom handles as a finished product. In addition, be utilized P...

The use of computer vision techniques in the medical field has been commonplace since the 1960’s when image analysis was used for chromosome pairing [1]. The used of these techniques in recent years has grown to encompass endoscopy, tool inventory recording, and surgical tool tracking in vivo. Given the potentially life altering stakes for these medical applications, a high degree of accuracy i...

Occupational skin disease is a problem of major importance in the engineering industry. Little is known about the occupational distribution of oil folliculitis and its varying degrees of severity. This investigation was undertaken in an attempt to discover which occupations are at risk and why. The study was conducted at an engineering factory where 200 men, whose daily work brought them in con...

The surface finish between two mating parts in an assembly has significant influence on the mechanical properties such as wear resistance, corrosion resistance, fatigue resistance and stress concentration. The choice of surface finishing operation such as honing and lapping is based on functional requirements of an assembly. As these processes are expensive, the design engineer should be cautio...

The aim of this study was to determine quantitatively and qualitatively the inorganic particle fraction of commercially available dental elastomers. The inorganic volumetric fraction of two addition silicones (Reprosil Putty/Fluid and Flexitime Easy Putty/Fluid), three condensation silicones (Clonage Putty/Fluid, Optosil Confort/Xantopren VL and Silon APS Putty/Fluid), one polyether (Impregum S...
