“…In spite of many advantages of the use of cutting fluids in the machining processes, they have serious disadvantages, such as ecological and economical problems, which have guided research works in the last decades to reduce or even eliminate the use of metal fluids [2][3][4][5][6]. During grinding many of the abrasive grits are in contact with the work piece each second, but just a portion of these grits have the cutting role in the real process and the others do not perform real cutting, but instead generate heat by rubbing and ploughing the work piece surface in the grinding contact zone.…”

“…In general, the functions of the fluid include: mechanical lubrication of the abrasive contacts, chemo-physical lubrication of the abrasive contacts, cooling in the contact area particularly in creep grinding, bulk cooling outside the contact area, flushing or the transport of the debris away from the abrasive process, transport of abrasive to a loose abrasive process, entrapment of abrasive dust and metal process vapors [1,2]. In spite of many advantages of the use of cutting fluids in the machining processes, they have serious disadvantages, such as ecological and economical problems, which have guided research works in the last decades to reduce or even eliminate the use of metal fluids [2][3][4][5][6].…”

In dry grinding, as there is no coolant lubricant to transfer the heat from the contact zone, generation of surface damages are not preventable. Promising alternatives to conventional flood coolant applications are also Minimum Quantity Lubricant (MQL) or Near Dry Machining (NDM) or Semi Dry Machining (SDM). As the name implies, MQL machining uses a very small quantity of lubricant delivered precisely to the cutting zone. Often the quantity used is so small that no lubricant is recovered from the parts. Any remaining lubricant may form a film that protects the parts from oxidation or the lubricant may vaporize completely due to high temperatures of the cutting zone. A number of studies have shown that MQL grinding can show satisfactory performance in practical grinding processes. However, there has been little investigation of cutting fluids to be used in MQL grinding. In this study, several grinding fluids, including mineral, vegetable and synthetic esters oil, are compared on the basis of the grinding forces and surface quality properties that would be suitable for MQL grinding applications, to develop a multifunctional fluid having the MQL results such as cooling, lubrication and high ecological and environmental safety performances. The grinding performance of fluids is also evaluated in dry and conventional fluid grinding techniques.

“…This can be realized by using specially manufactured grinding wheels with a segmented abrasive coating or with a defined grain pattern [3,4,5,6]. Other researchers have developed a special dressing method to generate a reduced effective contact area or have applied laser techniques for machining voids into the coating [7,8]. In summary, most of the concepts require non-standard grinding tools or a cost-intensive manufacturing process, such as laser technology for creating a patterned grinding wheel topography.…”

In this paper a new and innovative method for the patterning of grinding wheels is presented. The patterns are machined with a patterning tool by using fly-cutting kinematics. By changing the patterning process parameters different pattern sizes and densities can be machined in a flexible way. Surface and cylindrical grinding experiments show that grinding with patterned grinding wheels can significantly reduce process forces, grinding burn and grinding power. The surface roughness increases because less active cutting edges remain when grinding with patterned wheels. But especially for roughing processes the results show great potential for increasing the overall grinding performance.

“…Dessa forma, Sokovi & Mijanovic (2001) relataram que as empresas estão sendo forçadas a implementar estratégias de refrigeração menos nocivas no processo de usinagem. Assim, Tawakoli et al (2007) mostra que uma das estratégias para promover diminuição do uso de fluidos de corte é otimizar o fluxo de fluido, situação que ocorre com o uso da mínima quantidade de lubrificante (MQL).…”

RESUMO:Tornam-se notáveis, nos dias atuais, as pesquisas na área de usinagem dos materiais no que diz respeito à substituição das tradicionais formas de lubri-refrigeração com fluidos de corte em abundância por novas técnicas que reduzam o uso de tais fluidos. Essa ideia vem atrelada aos ideais de respeito ambiental e preservação da saúde humana que são prejudicados quando se faz uso dos fluidos de corte, devido à composição química característica dos mesmos.
