Control of thermal damage in grinding by digital signal processing of raw acoustic emission
(Proceedings of the 7th International Conference on Control, Automation, Robotics and Vision, ICARCV 2002, 2002-12-01) [Trabalho apresentado em evento]
Grinding process is usually the last finishing process of a precision component in the manufacturing industries. This process is utilized for manufacturing parts of different materials, so it demands results such as low ...
The cutting time with abrasive discs can be reduced by the control of the cutting speed
(Technical Paper - Society of Manufacturing Engineers. MR, 1997-12-01) [Artigo]
This paper presents an experimental study on the life of abrasive discs in cut-off type operations with two conditions of cutting speed. The cutting time is shown with a comparative analysis of the cutting speed.
Evaluation of different methods of cooling-lubrication in cylindrical grinding of advanced ceramic dip
(Materials Research, 2014-10-01) [Artigo]
The current work presents a study of alternative methods of cooling-lubrication for the external plunge grinding of advanced ceramics using diamond wheels. These two alternative methods, which are intended to reduce cutting ...
Grinding of hardened steels using optimized cooling
(Ingeniare, 2008-06-01) [Artigo]
