Transverse cylindrical grinding of a eutectic alloy
(2003-01-01)
We report herein on a comparison of the performance of two different grinding wheels (conventional and CBN) in the transverse cylindrical grinding of a eutectic alloy. Three cutting conditions were tested: rough, semi-finishing ...
Transverse cylindrical grinding of a eutectic alloy
(2003-01-01)
We report herein on a comparison of the performance of two different grinding wheels (conventional and CBN) in the transverse cylindrical grinding of a eutectic alloy. Three cutting conditions were tested: rough, semi-finishing ...
A novel dressing technique for texturing of ground surfaces
(TECHNISCHE RUNDSCHAU EDITION COLIBRI LTD, 2010)
This work presents a novel dressing technique that allows the inscription of pre-configurable patterns, or textures, on the grinding wheel surface. An electro-mechanical exciter connected to the dressing tool receives ...
Depth of dressing optimization in CBN wheels of different friabilities using acoustic emission (AE) technique
(Springer, 2020-02-01)
Grinding is a manufacturing process that has the objective of granting the workpiece a high-quality surface and is located at the end of the sequence of machining processes. During grinding operation, the abrasive grains ...
Monitoring the dressing operation in the grinding process
(2009-03-03)
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. ...
The Grinding Wheel Performance in the Transverse Cylindrical Grinding of an Eutetic Alloy
(ABM, ABC, ABPol, 2002-10)
This paper presents a research in which the performance of two different grinding wheels (a conventional and a CBN wheel) was evaluated in a transverse cylindrical grinding of a eutectic alloy. Three cutting conditions ...
In-Dressing Acoustic Map by Low-Cost Piezoelectric Transducer
(Ieee-inst Electrical Electronics Engineers Inc, 2020-08-01)
The main difficulty in the grinding process is to identify the correct moment to dress the grinding wheel. Therefore, the cutting tool (grinding wheel) must be monitored. In this context, an innovative technique was developed ...
Tool condition monitoring of aluminum oxide grinding wheel in dressing operation using acoustic emission and neural networks
(Springer, 2015-03-01)
The grinding operation gives workpieces their final finish, minimizing surface roughness through the interaction between the abrasive grains of a tool (grinding wheel) and the workpiece. However, excessive grinding wheel ...
Acoustic image-based damage identification of oxide aluminum grinding wheel during the dressing operation
(2019-01-01)
Grinding is a finish process of parts that require high precision and tight dimensional tolerance, which owe high value-added. As the grinding process takes place, the cutting surface of the grinding wheel undergoes wear ...
