Topographical analysis of machined surfaces after grinding with different cooling-lubrication techniques
(Elsevier B.V., 2020-01-01)
The search for more sustainable grinding processes resulted in alternative cooling-lubrication techniques, as minimum quantity lubrication (MQL). However, this shift changes the associated tribosystem and, thus, the surface ...
Y-TZP zirconia regeneration firing: Microstructural and crystallographic changes after grinding
(2017-01-01)
This study evaluated microstructural and crystallographic phase changes after grinding (G) and regeneration firing/anneling (R) of Y-TZP ceramics. Thirty five bars (Lava™ and Ice Zirkon) were divided: Y-TZP pre-sintered, ...
Correlating surface roughness and vibration on plunge cylindrical grinding of steel
(Pergamon-elsevier Science LtdOxfordInglaterra, 2003)
Influence of water in the MQL technique in the grinding of steel AISI 4340 using CBN wheels
(Fundação Gorceix, 2018-07-01)
Abstract Usually, machining employs cooling methods to avoid high temperatures. In most cases, the cutting fluid is applied with high flow and low pressures. This technique consumes a large amount of cutting fluid that ...
Classification of burn degrees in grinding by neural nets
(2008-12-01)
One of the problems found in the implementation of intelligent grinding process is the automatic detection of surface burn of the parts. Several systems of monitoring have been assessed by researchers in order to control ...
Contribution to cylindrical grinding of interrupted surfaces of hardened steel with medium grit wheel
(Springer, 2018-04-01)
Grinding is generally the first choice to provide combination of both superior surface finish and closer dimensional tolerances in a machined component. This process can be employed in manufacturing of continuous and ...
Grinding performance using variants of the MQL technique: MQL with cooled air and MQL simultaneous to the wheel cleaning jet
(Springer, 2019-12-01)
The hardening of legislation in favor of socio-environmental preservation and the sustainable focus of industry are changing the current manufacturing methods, among which is grinding. This abrasion machining technique ...
Evaluation of the oil flow using the MQL technique applied in the cylindrical plunge grinding of AISI 4340 steel with cbn grinding wheel
(Fundação Gorceix, 2018-07-01)
Abstract The grinding process is defined as an abrasive cutting action of a tool known as grinding wheel, which is submitted to high rotations, promoting excellent finishing and accuracy in dimensions, respecting the ...
Grinding performance of AISI D6 steel using CBN wheel vitrified and resinoid bonded
(Springer, 2019-10-21)
In the last decades, manufacturers attracted much attention to developing processes with competitivity, sustainability, and productivity. One of the most important developments was related to employing more efficient tools. ...
