Evaluation of WEDM Surface Quality

Advanced Materials Research, 2010
The formation of WEDM surface is a complicated process. There are many factors which make machined surface topography have the characteristics of complex and irregular, and impact using performance of parts. The work investigated microscopic features of the WEDM surface topography based on power spectral density and fractal theory, and proposed power ...

Meaningful Surface Roughness and Quality Tolerances

International Optical Design Conference and Optical Fabrication and Testing, 2010
Meaningful surface quality and roughness tolerances can be derived based on physics and requirements rather than history and inertia. This paper describes how to develop such specifications for these annoying parameters.

Surface Water Quality Assessment by Environmetric Methods

Environmental Monitoring and Assessment, 2006
This environmetric study deals with the interpretation of river water monitoring data from the basin of the Buyuk Menderes River and its tributaries in Turkey. Eleven variables were measured to estimate water quality at 17 sampling sites. Factor analysis was applied to explain the correlations between the observations in terms of underlying factors ...

SURFACE ENGINEERING: PROVING THE QUALITY

Surface Engineering, 1993
Surface engineering is an enabling technology which can provide specialist surface properties while preserving the important structural features of the substrate. It can also save energy, reduce wear and corrosion, and, importantly, conserve rare materials by localising specialist properties at the surface rather than their needing to obtain ...

On the quality and integrity of broached surfaces

The International Journal of Advanced Manufacturing Technology, 2018
Surface integrity or in other words surface quality is a general term that is widely used in academia and industry to describe the characteristics and attributes of the workpiece surface after being modified or altered by manufacturing processes. Quality and integrity of the workpiece surface is a key design factor particularly when the part is likely ...

Quality of the Surface Waters in the Parma Valley of Italy

International Journal of Environmental Studies, 1987
Over the last three decades, the quality of the Val Parma water courses has undergone a drastic deterioration that can be linked to industrial and demographic transformation which have occurred there. From 1951 to 1981 there was a 360% increase in the pollution load by human activities with most of that increase occurring between 1961 and 1971. In 1976
