Avaliação da eficiência energética no processo de retificação de metal duro
(Universidade Federal de São Carlos, 2022-02-17)
The quest to make manufacturing processes sustainable is an increasingly important need. In this context, the present work assessed the grinding process of cemented tungsten carbide inserts with SNGN geometry (square, with ...
Modelagem da rugosidade de insertos de metal duro com base na topografia do rebolo
(Universidade Federal de São Carlos, 2023-02-13)
After sintering, cemented tungsten carbide cutting inserts are ground so that the final
dimensions can be obtained and surface defects can be reduced. To quantify the
insert surface quality after the finishing process, ...
Processo de dobramento a frio de chapas finas metálicas: análises por elementos finitos, experimentos e uma proposta para a compensação do retorno elástico
(Universidade Federal de São Carlos, 2022-07-26)
Mechanical forming operations are developed in several applications in industrial environments and are divided into some different operations, including cutting, bending, forging. Among the various processes, the bending ...
Estudo da influência do ângulo de hélice em brocas de metal duro na furação de alumínio aeronáutico
(Universidade Federal de São Carlos, 2022-02-23)
The use in machining aluminum alloys offers many advantages: high cutting speed, low cutting forces, minimal tool wear and relatively low machining temperature. When machining aluminum alloys, it is always advisable to use ...
Previsão do crescimento de grão por elementos finitos a partir da recristalização dinâmica em um processo de laminação a quente de liga de aço SAE 4140
(Universidade Federal de São Carlos, 2022-02-23)
In the present study, we analyzed the influence of the parameters relevant to the Avrami model to describe the dynamic recrystallization kinetics and the final size of the recrystallized grains, in addition to their ...
Aplicação do shunt piezoelétrico para controle passivo de chatter no processo de torneamento da liga Ti-6Al-4V ELI
(Universidade Federal de São Carlos, 2022-08-01)
One of the main limitations for increasing the productivity of machining processes is the emergence of self-excited vibrations. This type of phenomenon, commonly called chatter, arises due to the interaction of the cutting ...
Modelagem de curvas de fluxo plástico de um aço bifásico utilizando inteligência artificial
(Universidade Federal de São Carlos, 2022-01-21)
The data used for the development of this work were obtained from previous research, in which samples of a super duplex stainless steel with ferritic matrix and dispersed austenite particles were deformed with torsion tests ...
Processo de estampagem incremental do alumínio QQ-A-250/5 (2024-T3): análises por elementos finitos e experimentos
(Universidade Federal de São Carlos, 2022-07-27)
The single point incremental forming method performed without die support is suitable for small batch and prototype product manufacturing due to the lower cost involved in its tooling acquisition, simplicity and flexibility ...
Investigação da influência da temperatura sobre a resistência mecânica, qualidade superficial e dimensional de peças impressas pela técnica FPM
(Universidade Federal de São Carlos, 2022-09-22)
Additive manufacturing has become a common practice across various industries due to its ability to efficiently produce complex parts on low and mediun scale. Among the various adopted techniques, the Fused Pellet Modeling ...
Análise das características superficiais da liga Ti-15Mo após torneamento com ferramentas de diferentes geometrias
(Universidade Federal de São Carlos, 2021-03-16)
It is consolidated that the machining of titanium alloys poses obstacles due to their low
machinability, which is related to the maintenance of mechanical resistance at high
temperatures, the low thermal conductivity, ...
