Heat Flux in Cutting: Importance, Simulation and Validation

Abstract: The trends of machining difficult-to-machine materials and of dry machining or MQL lead to high temperatures in the cutting zone and increase the importance of thermal factors in the machining process. Besides amplified thermal tool loading and wear, the thermal fluxes affect the machining accuracy due to thermo-elastic deformations. Thus it is extremely important to know the magnitudes of these heat flows in order to assess the machining process heat and the tool wear and to develop compensation strategies ag… Show more

“…10 s), (ii) practically stabilizes with small residual oscillations at a certain level or demonstrates a slow growth, and (iii) decreases over a short period of time (approximately 5 s) after tool disengagement [10,13,14,15]. Other researchers [17,18,19] reported constant or near-constant heat flux behavior over the machining time. However, this flux behavior differs from the behavior observed during metal cutting, where the temperature in the primary, secondary and tertiary zones reaches its maximum value almost instantly [1].…”

“…This is the first hypothesis of flux behavior over time. But in the studies devoted to spatial distribution of heat flux [17,18] and in [19], the flux was considered to be constant over time. This is the second hypothesis shown in Fig.…”

“…Therefore, some studies have investigated the relationship between thermal number and heat distribution ratio. Heat value parameters were applied to establish a calculation method for heat distribution ratio under continuous cutting conditions by Putz et al [21]. Moreover, Putz et al [22] extended the same parameters to the calculation of the heat distribution ratio in an interrupted cutting process.…”
