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 ...
Tool Condition Monitoring of Single-Point Dresser Using Acoustic Emission and Neural Networks Models
(IEEE Transactions on Instrumentation and Measurement, 2014-03-01) [Artigo]
Identification and online monitoring of the dresser wear are necessary to guarantee a desired wheel surface and improve the effectiveness of grinding process to a satisfactory level. However, tool wear is a complex phenomenon ...
Utilization of Minimum Quantity Lubrication (MQL) with Water in CBN Grinding of Steel
(Materials Research-ibero-american Journal of Materials, 2014-01-01) [Artigo]
The use of cutting fluids is fundamental to machining processes, mainly when it comes to high heat generation, which is the case of grinding. Thus, lubrication and cooling provided by cutting fluids improve the final quality ...
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 ...
