“…Consequently, cutting fluid is not benefit for both environmental and work environmental sustainability and the elimination on the use of cutting fluid, if possible, can be a significant incentive (Suresh Kumar Reddy et al, 2010). By contrast, dry cutting with no cutting fluid is popular recently due to it is free from waste pollution, which seems to be good and friendly in environment.…”

“…The interest of researchers in the minimum quantity of lubrication (MQL) cooling-lubrication technique as an alternative to the conventional coolant delivery one (flooding coolant) has grown in the last decades seeking to reduce the large amount of cutting fluid used in machining operations, as well as the negative environmental impact and health problems caused by them [9]. In the MQL technique, the coolant usage is dramatically reduced from liters per minute to milliliters per hour, since it is delivered directly into the cutting zone as a mixture of small oil droplets and compressed air (0.6 MPa) which can be seen as a fluid mixture [10].…”

In a context where there is a continuous search for more environmentally friendly machining processes (for example, the implementation of the minimum quantity of lubrication-MQL-cooling-lubrication technique) and the constant concern with the high heat generation during the grinding process, there is still a lack of information about grinding of steel for molds and dies. Thus, the present work sought to evaluate the performance of tangential surface grinding of a steel for plastic injection molds, testing by two types of conventional abrasives (green silicon carbide and white aluminum oxide) under three different equivalent chip thicknesses. The performance of the MQL cooling-lubrication technique compared to the conventional one (flood coolant) was also evaluated. The output parameters to assess the surface integrity were the surface roughness (R a parameter), residual stresses and SEM images of the ground surfaces, as well as microhardness below the machined surface. The results shown that both conventional abrasives types have potential to be used in grinding of this steel, once low surface finish values (R a < 0.2 μm) and workpieces free of damages were fabricated. Silicon carbide (SiC) grinding wheel in general outperformed the aluminum oxide (Al 2 O 3) one in terms of surface roughness after machining under severest conditions (R a < 0.35 μm). Residual stresses were predominantly compressive irrespective of the cooling-lubrication technique and type of abrasive employed. Despite lower surface roughness and compressive residual stresses generated after grinding with the Al 2 O 3 grinding wheel, drop in hardness below the machined surface was observed, unlike when machining with SiC grinding wheel. MQL technique proved to be more effective than conventional coolant technique under the conditions investigated, irrespective of the grinding wheel used, and in some situations, it outperformed the conventional technique.

“…In order to overcome these disadvantages, the application of a proper metal cutting fluid is critical in metal forming processes. Cutting fluids must satisfy two essential functions: cooling and lubrication [2]. When the cutting zone is properly lubricated, cutting becomes more effective, through decreasing friction to a lesser extent [3].…”

Design and Validation of A Modular Instrument to Measure Torque and Energy Consumption in Industrial Operations

A modular torque measuring instrument capable of performing tapping torque tests (TTT) according to the ASTM D-5619 standard was designed, developed, and validated. With this new instrument, the performance of different lubricants can be evaluated in terms of frictional torque and energy consumption during tapping processes. This instrument can adapt onto any conventional milling machine or CNC machine and operate under various machining operations such as tapping, drilling, and other processes. To validate the design and performance of this new device, three commercially available lubricants were evaluated. From the three tested conditions, the results showed good repeatability, with consistent results throughout the different tests for each lubricant. The impact of such a proposed instrument ranges from academic use to industrial business use.
