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 ...
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 ...
