Metalworking fluid emulsion formulations produced from vegetable oils may be less toxic and may reduce disposal costs when compared with fluids formulated with petroleum-based oils. Experiments were performed on experimental emulsions made with unmodified and modified soybean oils to measure rates of mist production by impaction, centrifugal force and evaporation/recondensation mechanisms. Resu...

11 12 The biological treatment of spent synthetic metalworking fluid (MWF) has been investigated in many studies, 13 with most reporting the presence of un-degraded components in the residual waste. In this study, we 14 investigated a hybrid approach to waste treatment of spent MWF, involving both physical treatment and 15 microbial degradation. The effect on biological degradation, of the remo...

Metalworking-fluids (MWFs) perform essential functions to metal-products manufacturing industry. MWFs also have inherent environmental and health liabilities associated to industry. These liabilities viewed as opportunity to reevaluate the functionality of MWFs and improve profitability of operations. Several problems appeared in using of MWFs including biodegradation of constituents. The objec...

In the metalworking industries of the most industrially developed countries forging remains one of the dominating technologies. In order to achieve optimal performance throughout the various phases of design process, computer aided technologies must be applied extensively. Special importance is placed upon CAM simulations as an important aid in optimization of process planning. This paper is fo...
