Influência da lubrirrefrigeração na qualidade superficial de metais retificados

Abstract: Na fabricação de componentes mecânicos precisos, que necessitam de alta resistência mecânica e ao desgaste, utiliza-se o processo de retificação, para conferir o acabamento final desejado e, também, para eliminar as deformações ocorridas durante a têmpera do aço. No entanto, as condições de retificação devem ser adequadas, para que não sejam introduzidas falhas na peça. Novos conceitos de lubrificação e refrigeração, para o processo de retificação, estão sendo pesquisados, de forma a diminuir os custos e os da… Show more

“…It can be observed that there is a trend of increasing roughness as infeed rate increases for the TS type (same number of grooves). According to Alves et al (2011), grinding wheel speed affects workpiece surface finishing by means of changing tangential cutting force, which increases surface roughness as the force soars up. Thereby, surface roughness is increased as the infeed rate increases from 0.25 mm/ min to 0.75mm/min.…”

“…All these factors have made several researchers seek for possible solutions to such problems. Finally, they were able to demonstrate that intermittent grinding (for grooves on grinding wheel) is a promising method to reduce both the average force of grinding (Fan and Miller, 2006) as well as thermal damage due to its excellent cooling effect (Kwak and Ha, 2001;Alves et al, 2011).…”

“…All these factors have made several researchers seek for possible solutions to such problems. Finally, they were able to demonstrate that intermittent grinding (for grooves on grinding wheel) is a promising method to reduce both the average force of grinding [3] as well as thermal damage due to its excellent cooling effect [5,6]. According to [7], discontinuous cutting is a cutting process in which the tool is now in contact with the workpiece, but sometimes loses this contact (inactive time).…”
