Influence of optimized lubrication-cooling and minimum quantity lubrication on the cutting forces, on the geometric quality of the surfaces and on the micro-structural integrity of hardened steel parts
(Revista Materia, 2012-05-25) [Artigo]
The is paper presents an analysis of the influence of minimum quantity lubrication (MQL), optimized and conventional cooling, using different cutting fluid volumes and flow rates, on the surface quality and integrity of ...
Performance Evaluation of the Minimum Quantity of Lubricant Technique With Auxiliary Cleaning of the Grinding Wheel in Cylindrical Grinding of N2711 Steel
(Journal Of Manufacturing Science And Engineering-transactions Of The Asme, 2017-12-01) [Artigo]
Grinding is an abrasive process mostly used in finishing operations to provide low roughness and narrow limits of form and dimensioning to the workpiece. Due to the large amount of heat generated by friction between the ...
Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation
(Iet Science Measurement & Technology, 2017-08-01) [Artigo]
Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...
MQL with water in cylindrical plunge grinding of hardened steels using CBN wheels, with and without wheel cleaning by compressed air
(International Journal Of Advanced Manufacturing Technology, 2017-04-01) [Artigo]
Minimum quantity of lubricant (MQL) in grinding is an alternative for reducing abundant fluid flow and both environmental and health hazards when compared with conventional fluid application. In spite of the fact that MQL ...

(Rem: Revista Escola de Minas, 2003-06-01) [Artigo]
Nesse artigo é apresentada uma pesquisa experimental sobre os danos térmicos que aparecem nas válvulas de admissão dos motores após passarem pelo processo de retificação. Foram utilizados, nessa experimentação, quatro tipos ...
Grinding of AISI 4340 steel with interrupted cutting by aluminum oxide grinding wheel
(REM. Revista Escola de Minas, 2015) [Artigo]
There has been a great advance in the grinding process by the development of dressing, lubri-refrigeration and other methods. Nevertheless, all of these advances were gained only for continuous cutting; in other words, the ...
Plunge cylindrical grinding with the minimum quantity lubrication coolant technique assisted with wheel cleaning system
(International Journal Of Advanced Manufacturing Technology, 2018-03-01) [Artigo]
MQL technique is considered as a cleaner machining compared to the conventional coolant delivery one, thereby ensuring environmental sustainability and economic benefits. However, one of problems commonly reported when ...
Evaluation of grinding process using simultaneously MQL technique and cleaning jet on grinding wheel surface
(Journal Of Materials Processing Technology, 2019-09-01) [Artigo]
In the last years, many researchers have proposed improvements to the minimum quantity lubrication (MQL) technique, in order to increase its efficiency and make it a viable alternative to the conventional application of ...
Study on the effect of the temperature in Acoustic Emission Sensor by the Pencil Lead Break Test
(2018 13th Ieee International Conference On Industry Applications (induscon), 2018-01-01) [Trabalho apresentado em evento]
The Pencil Lead Break (PLB) method is used to reproduce an artificial source of acoustic emission. This method consists of breaking a pencil lead which has its size and thickness determined carefully in a certain angle in ...
Monitoring of Self-Excited Vibration in Grinding Process Using Time-Frequency Analysis of Acceleration Signals
(2018 13th Ieee International Conference On Industry Applications (induscon), 2018-01-01) [Trabalho apresentado em evento]
Grinding is a finish manufacturing process for high precision parts. As the part has high value added at this stage, anomalies and defects are unacceptable. Self-excited vibration or just chatter is an undesirable and ...
