“…Problematics of decreasing the thermal interactions in the cutting zone has been discussed by numerous researchers. Grinding with minimal quantity lubrication (MQL) provides efficient lubrication, reducing the grinding power and specific energy [15][16][17]. A decrease of thermal interactions in the grinding zone may be also obtained by the proper selection of processing parameters [18,19].…”

The results of grinding are highly dependent on conditions of workpiece removal process. The material is removed by an unspecified number of abrasive grains of irregular shape and random distribution on the grinding wheel active surface. The interaction between the abrasive grain and the workpiece can be divided into three stages: (i) rubbing, (ii) ploughing and (iii) chip formation. Reciprocal contribution of each stage is dependent on the properties of the workpiece, the grinding parameters, the friction condition between the abrasive grain and the workpiece and the shape of the grains. In the article, the results of numerical and experimental process in the analysis of grinding of Ti-6Al-4V titanium alloy, using a conventional grinding wheel and a newly developed grinding wheel with aggregates of grains, were presented. The analysis of influence of the geometric parameters of the abrasive aggregates and the abrasive grains on the effectiveness of the workpiece removal process is presented. The effects of the geometrical parameters of grains and abrasive aggregates in direction of motion as well as in transversal direction on the size of ridges were determined. It has been observed that increase of the length of sideway material displacement results in the decrease of ridge formation. The results of a numerical analysis were confirmed by experimental research. The analysis of the impact of utilization of abrasive aggregates on the grinding forces, grinding-specific energy and surface roughness was performed. The impact of abrasive aggregates on the decrease of grinding forces and specific energy and the increase of quality of ground surface was observed.

“…They found that the surface roughness, diametric wear, grinding forces and residual stress improved when using the latter, due to optimum lubrication of the grinding zone, providing rather grain slipping at www.intechopen.com the contact zone (Silva et al, 2005;Silva et al, 2007). Brunner showed that the MQL grinding with a 4 ml/min ester oil (comparing to 11 ml/min mineral oil), when machining 16MnCr5 (SAE-5115) steel with microcrystalline aluminum oxide reduced the process normal and tangential forces to one third, however increasing the surface roughness by 50% (Tawakoli et al, 2009). Investigations by Brinksmeier confirmed these results and showed in addition that the type of coolant used during MQL grinding (ester oil or emulsion) can considerably influence the process result (Tawakoli et al, 2009).…”

Hafenbraedl and Malkin found that MQL provides efficient lubrication, reduces the grinding power and the specific energy to a level of performance comparable or superior to that obtained from conventional soluble oil (at a 5% concentration and a 5.3 l/min flow), while at the same time it significantly reduces the grinding wheel wear.…”

“…The completeness of the processed workpiece surface also deteriorates. Tawakoli et al (2009) researched the impact of grinding parameters on the workpiece surface quality in a flat grinder experiment. Compared with flood cooling wet grinding, the workpiece surface quality improves under the conditions of optimisation of grinding consumption and feed liquid parameters, with improved quality, reduced tangential grinding force, and decreased specific grinding energy.…”

Abstract:The heat-transfer model of a surface grinding temperature field with a nanoparticle jet flow of minimum quantity lubrication (MQL), as well as the proportionality coefficient model of the energy input workpiece, was established. Numerical simulation of the surface grinding temperature field of a nano-ZrO 2 dental ceramic workpiece material was conducted. With increased cut depth, the peak values of grinding temperature rocketed. With increased workpiece feed speed, grinding temperature on the finished surface decreased. With increased wheel peripheral speed, a high amount of heat energy accumulated on the surface because of the low heat-transfer coefficient of the ceramic material, and a large temperature gradient appeared in the temperature distribution layer. Under the same cooling and lubrication conditions, grinding temperature insignificantly changed along the direction of grinding width. Conversely, under different cooling conditions, the temperature variation was significant. MQL grinding conditions with additive nanoparticles significantly affected the weakening of temperature effect on the grinding zone.Keywords: grinding; temperature field; nano-ZrO 2 dental ceramics; nanoparticle jet; minimum quantity lubrication; MQL.Reference to this paper should be made as follows: Wang, S., Li, C., Jia, D.
