“…From experimental data in Fig. 4, it also can be explicitly observed that normal forces always show about 3 times larger values than tangential forces, which can be predicted due to the high rubbing and ploughing activity of abrasive grains with a large negative rake angle [1].…”

“…Inadequate cutting conditions can result in the creation of surface failures such as thermal burn, tensile residual stress, debris adherence, and rapid tool wear, etc. Together with selecting adequate grinding conditions, the employment of cutting fluid is also an effective strategy to enhance grinding performance [1]. With the introduction of enough cooling and lubricating activity, heat formation in the interaction region and thermal failure can be depressed.…”

The experiments of the surface grinding of Ti-6Al-4V grade 5 alloy (Ti-64) with a resin-bonded cubic Boron Nitride (cBN) grinding wheel are performed in this research to estimate the influence of cutting parameters named workpiece infeed speed, Depth of Cut (DOC), cooling condition on the grinding force, force ratio, and specific energy. A finite element simulation model of single-grain grinding of Ti-64 is also implemented in order to predict the values of grinding forces and temperature. The experimental results show that an increase of workpiece infeed speed creates higher intensified cutting forces than the DOC. The grinding experiments under wet conditions present slightly lower tangential forces, force ratio, and specific energy than those in dry grinding. The simulation outcomes exhibit that the relative deviation of simulated and experimental forces is in the range of 1-15%. The increase in feed rate considerably reduces grinding temperature, while enhancement of DOC elevates the heat generation in the cutting zone.

“…Experiments have been performed on a horizontal surface grinder of HMT Praga made, in up-grinding mode in both dry and wet environments using identical SiC wheels. The use of SiC wheel for grinding titanium alloys is supported by many researchers [17][18][19], due to the superior friability of silicon carbide abrasive grits that enables to retain their sharpness for longer period of time. Also SiC grits have a tendency to withstand higher temperature without being glazed out as compared to alumina grits [1].…”

Improving grindability of a given material with the application of cutting fluid is a well-established strategy. However, demands from sustainable manufacturing strive for reduction in cutting fluid consumption as well as introduction of unconventional coolants of non-toxic origin to be employed during the operation without sacrificing its performance. Present experimental investigation deals with the analyses of the performances of some unconventional cutting fluids viz. soap water, sodium nitrite and propylene glycol under small quantity lubrication while grinding Ti-6Al-4V using silicon carbide wheel. Relevant parameters to estimate grindability, like grinding force and specific energy requirements, surface roughness, grinding ratio (G ratio), SEM micrographs of ground surface and images of grinding chips are critically analysed and compared with the results obtained using conventional synthetic fluid and dry grinding. Results have revealed that the unconventional grinding fluids perform more satisfactorily. Among all the fluids applied, propylene glycol has provided with much superior grinding results. It has significantly reduced grinding forces, specific energy, surface roughness and improved G ratio while providing superior surface quality.
