Automação do sistema de lubrificação dos expulsores da máquina formax
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Manutenção IndustrialUTFPR, 2016-11-29)
This paper presents the design and implementation of an improvement for lubricationand automation of the main unit responsible for production. This prototype is constituted by a metal structure composed of a stainless-steel ...
Numerical simulation of the lubricant performance
(Elsevier Science Sa, 2008-03)
Due to the high pressures that are involved in tube hydroforming processes, high values of the friction forces are developed and, therefore, lubricants are usually employed to increase the formability of the workpiece. ...
Evaluation of different methods of cooling-lubrication in cylindrical grinding of advanced ceramic dip
(ABM, ABC, ABPol, 2014-10-01)
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 ...

Numerical analysis of the effects of material parameters on the lubrication mechanism for knee prosthesis
(Taylor & Francis Ltd, 2006-03)
The tibial component of current knee prostheses made of Ultra Hig Molecular Weigth Polyethylene (UHMWPE) has a high degree of wear that causes knee inflammation, prosthesis loosening and and subsequent replacement in no ...
Caracterização da tribologia como proposta de disciplina para um curso superior de Tecnologia em Manutenção Industrial
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilTecnologia em Manutenção IndustrialUTFPR, 2014-08-07)
The aim of this study was to conduct a study of Tribology, through literature. Thus, we sought to address the physical nature of friction and its consequences; Definition of wear, its mechanisms; forms of control associated ...

Influence of dimple shape on tribofilm formation and tribological properties of textured surfaces under full and starved lubrication
(Elsevier, 2019-08)
Lubrication conditions have significant influences on the formation of tribofilms and then affect tribological behavior. In this work, the influence of tribofilm formation on the tribological behavior of textured surfaces ...
Application of the auxiliary wheel cleaning jet in the plunge cylindrical grinding with Minimum Quantity Lubrication technique under various flow rates
(2018-05-01)
Minimum Quantity Lubrication is an alternative technique to conventional techniques that are related to environmental sustainability and economic benefits. This technique promotes the substantial reduction of the amount ...
