Influência da velocidade de estampagem e anisotropia no comportamento tribológico e fratura de uma chapa de aço AISI 430Nb

Abstract: RESUMO Na conformação de chapas metálicas, as propriedades mecânicas do material e os aspectos relacionados ao atrito têm sido uma das principais preocupações, pois têm grande influência na produtividade, qualidade do produto e custos de produção. Nesse contexto, é de extrema importância compreender e ser capaz de controlar os diferentes fatores que afetam o atrito durante o processo de deformação plástica. O objetivo deste trabalho foi investigar a influência da variação da velocidade de estampagem e da aniso… Show more

“…In most SMF processes, friction is an undesirable phenomenon due to the deleterious effects on equipment and products. Several parameters influence the tribological behavior of sheet metal during the forming process, for example, physicochemical phenomena, temperature, kinematics of tool movement, and dynamics of load [5,6].…”

“…In most SMF processes, the occurrence of friction is an undesirable phenomenon and causes [11][12][13][14] increased forming force, irregular deformation, and a reduction in product quality and tool life. The main parameters influencing tribological phenomena in SMF also include the dynamics of load, kinematics of tool movement, physicochemical phenomena occurring on the contact surface of the tool and workpiece and, finally, the temperature of the forming process [7,15,16]. The most effective way to reduce the unfavourable effects of the frictional forces on the quality of the product and the course of the forming process is the use of lubrication with the use of solid lubricants, oils or emulsions [17].…”
