Surface drag analysis after Ti-6Al-4V orthogonal cutting using grid distortion
(Elsevier Ltd, 2020)
Surface integrity directly affects the mechanical behavior of the workpiece, which is especially relevant on fatigue behavior. To characterize the quality of the machined surface, aspects such as material damage, roughness ...
Determining tool/chip temperatures from thermography measurements in metal cutting
(Elsevier, 2018)
Temperature measurement in metal cutting is of central importance as tool wear and surface integrity have been demonstrated to be temperature dependent. In this context, infrared thermography is presented as a reliable ...
Reduction of distortions in large aluminium parts by controlling machining-induced residual stresses
(Springer, 2018)
Large aluminium monolithic parts used in the aeronautic industry frequently show significant geometric distortions after the machining process. These distortions are the consequence of the initial residual stresses of the ...
Metal cutting experiments and modelling for improved determination of chip/tool contact temperature by infrared thermography
(Elsevier Ltd, 2015)
Temperature measurement in metal cutting at the chip and work contact is of central importance due to temperature dependence of tool wear and surface integrity. Infrared thermography is commonly employed to determine the ...
Uncertainty of Temperature Measurements in Dry Orthogonal Cutting of Titanium Alloys
(Elsevier, 2015)
Infrared radiation thermometer is used to measure the temperature of tool during dry orthogonal cutting of titanium alloys. The accuracy of measured temperature depends on several parameters such as the experimental set-up, ...
Evaluation of different flow stress laws coupled with a physical based ductile failure criterion for the modelling of the chip formation process of Ti-6Al-4V under broaching conditions
(Elsevier, 2019)
During the machining of Ti-6Al-4V the changing deformation mechanisms produce a complex microstructure of segmented chips, which directly influenced tool-wear and process stability. Numerical simulation could give an insight ...
Tool Damage and Adhesion Effects in Turning and Drilling of Hardened Steels
(World Academy of Science, 2016)
Noteworthy results have been obtained in the turning and drilling of hardened high-strength steels using tungsten carbide based cutting tools. In a finish turning process, it was seen that surface roughness and tool flank ...
Microstructural aspects of the transition between two regimes in orthogonal cutting of AISI 1045 steel
(Elsevier, 2018)
In depth understanding of tool-chip friction behavior is a significant aspect for tool wear performance in steels. In the present work attention has been paid to the strain mode of the chip section in contact with the rake ...
Exploring the effectiveness of using internal CNC system signals for chatter detection in milling process
(Elsevier, 2023)
Chatter is a harmful self-excited vibration that commonly occurs during milling processes. Data-driven chatter detection and prediction is critical to achieve high surface quality and process efficiency. Most existing ...
A tribological characterisation of Ti-48Al-2Cr-2Nb and Ti-6Al-4V alloys with dry, flood, and MQL lubricants
(Elsevier, 2023)
The development of cutting tools requires the knowledge of tribological phenomena at the tool – workpiece contact area. This knowledge is in dearth particularly for difficult-to-cut alloys like gamma titanium aluminide ...
