Grinding of hardened steels using optimized cooling
(Ingeniare, 2008-06-01) [Artigo]
Grinding - the final machining process of a workpiece - requires large amounts of cutting fluids for the lubrication, cooling and removal of chips. These fluids are highly aggressive to the environment. With the technological ...
In-process grinding monitoring through acoustic emission
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2006-01-01) [Artigo]
This work aims to investigate the efficiency of digital signal processing tools of acoustic emission signals in order to detect thermal damages in grinding processes. To accomplish such a goal, an experimental work was ...
Monitoring the dressing operation in the grinding process
(International Journal of Machining and Machinability of Materials, 2009-03-03) [Artigo]
This work was based on a methodology of development and experimentation, and involved monitoring the dressing operation by processing the acoustic emission and electric power signals to detect the optimal dressing moment. ...
Study of thresholds to burning in surface grinding process
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2005-04-01) [Artigo]
This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to ...
Evaluation of the thermal damages in inlet engine valves varying the grinding wheels and the cutting fluids
(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 ...
