“…An important role of these fluids is to reduce the thermal gradients shown to be present within the cutting zone of metal cutting processes. Chakraverti et al (1984) considered that the heat generated influences both the wear rate and the mechanical properties of the cutting tool material. As the cutting speed is increased the cooler region nearer the tool edge, a consequence of the workpiece acting as a heat sink, becomes narrower.…”

“…In discontinuous cutting processes, temperatures are cyclical, increasing during cutting periods and decreasing during non-cutting periods [21]. Thermal effects in discontinuous cutting can be a possible source for tool failure [22]. Direct experimental measures are also used to study the temperature in discontinuous cutting.…”

An experimental investigation on finish intermittent turning of UNS M11917 magnesium alloy under dry machining is presented. The objective of the study is the analysis of the chip morphology, surface quality and temperature when varying cutting conditions. The intermittent cutting process is analysed using three different workpieces (one continuous and two discontinuous). The experimental plan is based on full factorial designs. Main results of the investigation include the identification of the feed rate as the most important parameter to explain the surface roughness, while no clear influence was found for the cutting speed and slot width. The maximum temperature measured on the tool during the tests was below 50°C in all of the tests. These low temperature values are explained by the low machining times, depths of cut and cutting speeds used. Thus, for the range of the cutting parameters tested, finish operations can be performed using dry machining under safe conditions. In addition, it was identified that the increase of the depth of cut and feed rate led to higher maximum temperatures, while the increase of the slot width led to lower values. Finally, the morphology of the chips can be classified as segmented chips, including the arc, elemental and spiral chips. Thus, in terms of machining, these chips can be considered as favourable, but, in terms of ignition, these chips are more likely to ignite.

“…In early years, researchers modeled the cutting temperature by assuming cyclic heat flux or boundary temperature at the tool-chip interface, such as an exponential rise and fall in the interface temperature [5], a combination of cosine and exponential functions to define the interface temperature [6], a rectangular pulse heat flux [7], and a periodic harmonic heat flux [8]. The lack of adequate temperature measurements limited the ability of early authors to validate their modeling results.…”

This paper presents a novel technique to estimate the temperature distribution of a milling tool during machining. In this study, heat generation during the machining process is estimated using cutting forces. We consider the heat to be time-dependent heat flux into the tool. In the proposed model, we discretize each rake face on a mill into several elements; each experiences time-dependent heat flux. Second, we calculate the time-dependent heat flux as several constant heat input starts at different time. Finally, we sum the temperature rise from each heat flux to obtain the overall temperature change. A similar concept is applied on the flank surface, where the flank wear area is modeled as an additional heat generation zone. Experimental results are presented to validate the developed model.
