“…As illustrated in Figure 6, it can be observed that the contact area between tool and chip is time-varying, which is caused by the time-varying contact length between the tool and chip derived from Equation (22). Figure 6.…”

“…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. Tool coatings of different materials can have a significant impact on the generation and distribution of cutting heat within coated tools.…”

Modelling methods for the transient temperature field of wear land on the flank of end mills have been proposed to address the challenges of inaccurate prediction in the temperature field of end mills during the high-speed peripheral milling of Ti6Al4V that is a titanium alloy. A transient temperature rise model of wear land on the flank of end mills was constructed under the influence of heat sources in the primary shearing zone (PSZ), rake-chip zone (RCZ), flank-workpiece zone (FWZ), and dissipating heat source. Then the transient temperature field model of wear land on the flank of end mills was constructed. Finally, the transient temperature field model of wear land on the flank of end mills was constructed. Comparison of simulation result and experimental data verified the accuracy of the model. In sum, the proposed model may provide a temperature model support for future studies of flank wear rate in end mill modeling.

“…Each impulse produced by InAs and InSb voltage ratio is produced by cutting edge's heat passed through in front of optical fiber's input tip. The heat is produced by work done required by cutting tool to cut the workpiece and to overcome frictional force interaction between tools, chip and workpiece [39][40]. Infrared waves is radiated from the hot surfaces of cutting edge tool.…”

This paper describes the development of cutting temperature measurement of end mill tool by using infrared radiation technique approach. Compared to conventional thermocouple technique, infrared radiation technique is an advance method of measuring temperature which featured high accuracy, high response rate, wide range of temperature scale detection and almost compatible with all materials used in the manufacturing industry. We measures the emission of infrared radiation from the source, which is cutting edge of tool by using photocells that contains InAs and InSb photovoltaic detectors. Photocells converts the infrared radiation to a voltage signal and then recorded by oscilloscope followed with a calibration with its corresponding temperature. This paper discussed about the calibration method, cutting experiment setup, the limit of infrared radiation level detected by photocells, signal correction of output signal, and relations of peak signal formation with rotation of end mill tool. The developed pyrometer is also capable to profile the cutting tool’s rotation based on the movements of infrared radiation’s emission at cutting tool’s edge. The conclusion was that the measurement of cutting temperature of high speed machining by using infrared radiation technique is possible. The developed pyrometer are capable to detect temperature changes at a span of 0.01 ms.

“…To determine the heat distribution, researchers have studied heat fluxes into the tool, chip and workpiece. A number of papers have been devoted to heat flux determination in different machining processes such as deep grinding [5], high-speed drilling [7], dry machining of aeronautic aluminum alloy [9], MQL tapping and reaming [10] or devoted to prediction of heat flux distribution [6] and its effect on tool thermal deformation [8]. On the one hand, heat flux is the boundary condition (initial data) for the heat transfer equation, and on the other hand, it is a parameter that is almost impossible to measure due to the small area of the tool-chip contact and the aggressiveness of the cutting process.…”
