“…Currently, machinery mist reduction is preferred by most metal processing workshops to control the oil mist concentration, mainly including ventilator, oil mist catcher and machine shield [7,8]. Although these approaches are simple and effective, they still have some shortcomings.…”

Based on the dangers of suspended oil mist microparticles from machining to the environment and health of worker. A theoretical analysis on the generation mechanism of cutting fluid oil mist and an experimental study on its influencing factors were carried out in this paper. The experiment was conducted in closed lathe with flood cutting fluid feed system. A droplet diameter measuring system was equipped in the dense region of oil mist, which enables to observe the droplet distribution in air and scan the morphology of a single droplet accurately through its confocal microscopy. Droplet distribution and diameter were calculated through computer. In the experiment, effects of influencing factors on the oil mist concentration and average droplet diameter were discussed by controlling the revolutions per minute (rpm) of the main axis and cutting fluid flow, respectively. Experimental results demonstrated a significant effect of rpm on the characteristics of cutting fluid oil mist.As the rpm increased, the average droplet diameter decreased, whereas the oil mist concentration increased. As the cutting fluid flow increased, both of average droplet diameter and oil mist concentration increased.

“…Some scholars verified that the indoor PM2.5 concentration of households was over 5 folds of PM2.5 concentration in the atmospheric environment. PM2.5 concentration of workshops was over 30 folds of that of households [3][4][5][6][7]. Working at such a concentration, workers are facing serious health problem.…”

“…Dlatego w obróbce skrawaniem zaczęto stosować metodę MQL (bardzo małe ilości smarowania) lub MQCL (bardzo małe ilości chłodzenia i smarowania). Metody te pozwalają na skuteczne smarowanie w strefie skrawania, a co jest także bardzo istotne, są bardziej przyjazne dla środowiska [3].…”

StreszczenieZaprezentowano budowę i zasadę działania dwóch urządzeń wykorzystywanych podczas obróbki z minimalnym chłodzeniem i smarowaniem. Podano wartości wejściowych parametrów tworzenia mgły emulsyjnej dla urządzenia GAV 1500 i Micronizer Lenox (przepływ objętościowy powietrza i przepływ masowy emulsji). Wybrane parametry chropowatości uzyskane dla powierzchni obrobionej metodą MQCL poddano analizie regresyjnej i porównano z wynikami obróbki na sucho. Słowa kluczowe: urządzenie do tworzenia mgły emulsyjnej, metoda MQCL, obróbka na sucho, chropowatość powierzchni obrobionej THE IMPACT OF THE DESIGN OF EMULSION MIST GENERATING DEVICES ON THE MACHINED SURFACE ROUGHNESS AFTER THE CUTTING PROCESS OF C45 STEEL AbstractThe paper presents the design and principle of operation of two devices used during machining with minimum cooling and lubrication. The input parameter values for emulsion mist generation for the GAV 1500 and Micronizer Lenox device (air volume flow and emulsion mass flow) were given. The assorted roughness parameters obtained for a surface machined with the MQCL method were subject to regression analysis and compared with results of dry machining.

“…So, conventionally machining of these sticky material is carried out under flooded coolant/ wet conditions, which involves higher manufacturing cost on one hand and poses serious environmental and health hazards on the other hand. 1,2 In an attempt to economize the production cost in severe turning applications without switching over to costlier Ceramic and CBN tools, researchers are exploring the improvement in wear resistance of coated carbide tools during machining of sticky materials under MQL conditions, thereby lowering the high cutting forces as encountered in dry turning and negative impacts of flooded machining. Minimum quantity lubrication refers to the use of tiny amount of non-toxic biodegradable oil sprayed to the cutting zone by compressed air (50-500 mL/h, compared to 30,000-60,000 mL/hour in flooded machining) minimizing the friction, temperature and cutting forces generated during machining.…”

The benefits of cutting fluids in machining are well known, but their use is accompanied by health and environment hazards. Moreover, strict environmental regulations make the manufacturers to switch over to dry turning, which is not feasible during machining of sticky material like stainless steel and Inconel etc. Therefore, the use of minimal quantities of lubricant (MQL) can be regarded as an alternative solution and a step towards green machining. In the present investigation an attempt has been made to explore the potential of MQL turning of stainless steel with coated carbide cutting tool. Turning under MQL conditions has shown superior results (in terms of flank wear and machined surface roughness) over wet and dry turning. Signal to noise (S/N) ratio as per Taguchi design revealed speed and MQL as significant parameters for minimizing flank wear and surface roughness, whereas feed can be set within range. The optimum combination of parameters are cutting speed (58 m/min), feed rate (0.06 mm/rev.) and MQL flow rate (100 mL/h) for flank wear and cutting speed (23 m/min), feed rate (0.07 mm/rev.) and MQL flow rate (150 mL/h) for surface roughness. Taguchi optimized conditions were validated through multiple response optimization using desirability function.
