Many efforts have been made over the years to minimize usage of mineral oil-based MWFs. This includes trail its alternatives, such as vegetable MWFs, nanofluids, etc. These alternatives shown comparable results MWFs in producing a better surface finish and machining efficiency. Apart from conventional flooding several alternative techniques developed by researchers or eliminate including dry ma...

Considering the issues involved in industrial cutting and machining systems, and, in particular, the problems arising from the use of cutting fluids in these systems, this study presents the results of an analysis that points to a safe and efficient way to reduce contaminated microbial cutting fluids using ultraviolet radiation. The study proposes a transmitter system of simple ultraviolet radi...

During the past decade we have witnessed a tumultuous debate over the disease risks posed by microbes that inhabit metalworking fluid (MWF) systems. Not infrequently, that debate has occurred in the absence of satisfactory data. This paper addresses the author’s perspective on what types of data are needed in order to assess the actual disease risks posed by MWF microbes. The approach must be m...

The archaeometallurgy of copper have been pioneer technologies in ancient Iran and goes back to about ten thousand years ago in Iranian Plateau [1, 2]. The Haft Tappeh Middle Elamite Site is located in Southwest Iran and have been an important city belonging to early phase of Middle Elamite period (14th century BCE) [3, 4]. Based on various metallurgical evidences found in archaeological excava...

D. Mates, West University, Faculty of Economics, Timisoara; M. Socoliuc, “Stefan cel Mare” University, Faculty of Economics, Suceava, Romania. Despite the international economic crisis, the European Union has managed to maintain its important position in the world exports of metalwork manufactures, with slight imbalances recorded on its markets in 2010 and under circumstances of little importan...

Environmental opportunistic mycobacteria, including Mycobacterium avium, M. terrae, and the new species M. immunogenum, have been implicated in outbreaks of hypersensitivity pneumonitis or respiratory problems in a wide variety of settings. One common feature of the outbreaks has been exposure to aerosols. Aerosols have been generated from metalworking fluid during machining and grinding operat...
