The present study presents the influence of welding current, welding voltage, welding speed and external magnetic field on hardness of shielded metal arc welded mild steel joints. Mild steel plates of 6 mm thickness were used as the base material for preparing single pass butt welded joints. Speed of welding was provided by cross slide of a lathe machine, external magnetic field was obtained by...

The present investigation aimed at a sustainable green turning operation of Ti-6Al-4V alloy using multi-objective optimization surface roughness, tool flank wear, material removal rate, and wear loss with cutting speed, feed depth cut as input parameters. experiments were performed on CNC lathe machine an alumina-zirconia (Al2O3-ZrO2) ceramic insert under dry machining environment. to examine t...

The machining process is primarily used to remove material using cutting tools. Any variation in tool state affects the quality of a finished job and causes disturbances. So, monitoring scheme (TMS) for categorization supervision failures has become utmost priority. To respond, traditional TMS followed by machine learning (ML) analysis advocated this paper. Classification ML supervised based me...

Surface roughness is considered as one of the most specified customer requirements in machining processes. For efficient use of machine tools, selection of machining process and determination of optimal cutting parameters (speed, feed and depth of cut) are required. Therefore, it is necessary to find a suitable way to select and to find optimal machining process and cutting parameters for a spe...

This experimental workanalysis the influence of cutting conditions on surface roughness of EN-8during machining by CNC turning. Analysis of variance (ANOVA) is employed to investigate the influence of cutting speed, feed rate, and depth of cut and coolant type on surface roughness height Ra. The influence of the interaction of cutting speed, feed rate, depth of cut and coolant type on surface r...

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...

Tool condition monitoring in machining plays a crucial role in modern manufacturing systems, finding tool wear state in early with the help of monitoring system will reduce downtime and excessive power drawing while machining. It also increases machining quality as well as surface finish of machined components. Vibration analysis of mechanical systems can be used to identify the tool condition ...

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...
