Abstract

Nowadays, the metalworking industry is increasingly looking for high quality and precision parts. In this sense, grinding stands out for its high surface finishing ability in different types of materials. In view of this, we seek to improve two conditions still discussed in this machining process, the sustainability and the reduction of operator health risks. These problems arise from the use of cutting fluid in machining, but this technique is essential for reducing the heat generated during grinding and producing high-quality parts. As a result, alternatives to conventional cutting fluid are emerging in order to address both of the above conditions and maintain the quality required by today's productive means. One highlight is the Minimum Quantity of Lubricant (MQL), which has a tendency to present results close to those of the conventional method and, in addition, with extremely smaller amounts of fluid, increasing the sustainability of the process. On the other hand, traditional MQL (with pure oil) has an inefficient cooling capacity and causes intense grinding of the wheel. Thus, one way to minimize this limitation of MQL is to dilute the oil in water in the MQL system, increase its cooling power, and apply cleaning of the grinding wheel cutting surface. With this increase in refrigeration capacity, the applicability of MQL increases and can be used for example in ceramic grinding, which is very relevant in the industrial environment. In addition, an effective and relatively inexpensive method of controlling corrosion indoors is the use of volatile corrosion inhibitors (VCIs). These compounds can be used as temporary protectors and can be easily removed from the surface. VCI Brasil, in order to develop and apply new technology, has formulated a new class of corrosion inhibitors, which use water as a propagation medium and protective efficiency, being generically referred to as V-active VCI ®. This new composition and chemical grade made it possible to develop and formulate several other products that use water as a medium, generically referred to as MV Aqua ®, as degreasers, water-based protection agents and especially cutting fluids. Specifically, in the case of cutting fluid, this family of inhibitors when dissolved in water promotes a greater lubricity and detergency effect, leading to lower consumption of cutting tools (grinding wheel in the case of grinding), and consequently, better finishing. In addition, the fluid in question presents no risk to humans and is biodegradable. Therefore, this work aims to analyze the influence of oil-water dilution (with corrosion inhibitor) 1: 0, 1: 1, 1: 5, 1:10 and 1:20 on MQL with and without grinding wheel cleaning on external cylindrical grinding. diamond wheel alumina, which will be compared with the conventional method. For this, the input parameters will be varied and the results of the output parameters will be: arithmetic mean roughness (Ra), roundness deviation, grinding wheel diametric wear, acoustic emission, scanning electron microscopy, confocal microscopy, microhardness, and power. With this work, we seek to expand knowledge mainly in the area of rectification, given the exclusivity of the theme and the potential innovation generated by this research.
