Modeling of Drag Finishing: Influence of Abrasive Media Shape
(MDPI, 2021)
Drag finishing is a widely used superfinishing technique in the industry to polish parts under the action of abrasive media combined with an active surrounding liquid. However, the understanding of this process is not ...
In-SEM micro-machining reveals the origins of the size effect in the cutting energy
(Springer Nature, 2021)
High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability ...
Experimental evaluation and surface integrity analysis of cryogenic coolants approaches in the cylindrical plunge grinding
(Nature Publishing Group, 2021)
Replacement of pollutant fuids with eco-friendly strategies in machining operations signifcantly contributes to protecting the environment, diminishing global warming, and ensuring a healthier workplace for employees. This ...
Sensor signal selection for tool wear curve estimation and subsequent tool breakage prediction in a drilling operation
(Taylor & Francis, 2021)
Tool condition monitoring have an important role in machining processes to reduce defective component and ensure quality requirements. Stopping the process before the tool breaks or an excessive tool wear is reached can ...
Roughness maps to determine the optimum process window parameters in face milling
(Elsevier Ltd., 2022)
Some industrial applications require structured surfaces with high roughness values to ensure their functionality (Ra > 1 µm, Rmax < 30 µm). In order to obtain these structured surfaces with high roughness values, face ...
Identification of the Parameter Values of the Constitutive and Friction Models in Machining Using EGO Algorithm: Application to Ti6Al4V
(MDPI, 2022)
The application of artificial intelligence and increasing high-speed computational performance is still not fully explored in the field of numerical modeling and simulation of machining processes. The efficiency of the ...
Heat transferred to the workpiece based on temperature measurements by IR technique in dry and lubricated drilling of Inconel 718
(Elsevier, 2016)
In manufacturing aeronautical critical components, such as turbine discs commonly made of Inconel 718, surface integrity is crucial to ensure their fatigue life. Among the machining processes used, the drilling operation ...
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, ...
A Note on Interpreting Tool Temperature Measurements from Thermography
(Taylor & Francis, 2015)
Thermography (thermal imaging) is a well-established experimental method for studying cutting tool temperature distributions. In one form, cutting edge temperatures within the chip / tool contact area are deduced from ...
Sensitivity analysis of the input parameters of a physical based ductile failure model of Ti-6Al-4V for the prediction of surface integrity
(Elsevier Ltd, 2020)
In machining of Ti-6Al-4V, it is commonly reported the appearance of segmented chip produced by adiabatic shearing (at high cutting speeds) and lack of ductility (at low cutting speeds). Moreover, machining is a manufacturing ...
