Cutting temperature and energy partitioning in grinding
2021, Tribology and Fundamentals of Abrasive Machining Processes: Third EditionA 3D analytical thermal model in grinding considering a periodic heat source under dry and wet conditions
2021, Journal of Materials Processing TechnologyCitation Excerpt :These two mechanisms counterbalance each other and the final effect depends on the strength of each mechanism. There is a very moderate increase (Zhang et al., 2013), a decreasing trend (Howes et al., 1987) and constant behavior (Zhang et al., 2009) reported in the literature. As shown in Fig. 18, increasing the feed rate resulted in a very moderate decrease in the maximum temperature in this study and the model could predict the behavior with good accuracy (4.5 % and 12.5 % discrepancies with the measurements, respectively).
An useful analytical formula to avoid thermal damage in the adaptive control of dry surface grinding

2016, International Journal of Machine Tools and ManufactureCitation Excerpt :This confusing observation was explained as follows: for a standard GW (Fig. 8a left), the lubrication gap was formed in front of the contact zone where the coolant was under high pressure. This pressure would raise the boiling point of the coolant and delay the appearance of the film-boiling which rapidly deteriorates the cooling efficiency of the coolant [33,34]; For a slotted GW (Fig. 8a right), on the other hand, the slots diminished the formation of the high pressure and made the grinding-induced airflow being sucked into the slots forming the mist; thus, only a small amount of the coolant was transported into the contact zone. Based on this, a slotted GW was produced on whose surface 70 slots were milled inside, shifted symmetrically alongside the GW centerline, and slightly rotated by an inclination angle of 15° (Fig. 8b).
Manufacturing at double the speed
2015, Journal of Materials Processing TechnologyCitation Excerpt :The energy partition to the workpiece depends on the wheel and workpiece materials, and the operating conditions, including the delivery of coolant. Howes et al. (1987) note that a water based fluid would boil at 100 °C, so will be effective only if the temperature is kept below this point, but for shallow-cut grinding this is unlikely, so the fluid boils and in effect the grinding conditions become dry. Thus, in this case, although the fluids act as lubricants and reduce the energy input, they provide little cooling effect and the workpiece temperature rises rapidly.
