Investigation of Single-Point Dressing Overlap Ratio and Diamond-Roll Dressing Interference Angle on Surface Roughness in Grinding

Abstract

This paper investigates the effect of both single-point and diamond-roll dressing techniques on the workpiece surface roughness in grinding. Two empirical surface roughness models are studied – one that incorporates single-point dressing parameters, and another that incorporates diamond-roll dressing parameters. For the experimental conditions used in this research, the corresponding empirical model coefficients are found to have a linear relationship with the inverse of the overlap ratio for single-point dressing and the interference angle for diamond-roll dressing. The resulting workpiece surface roughness models are then experimentally validated for different depths of cut, workpiece speeds and dressing conditions. In addition, the models are used to derive a relationship between overlap ratio for single-point dressing, and interference angle for diamond-roll dressing such that both dressing techniques produce a similar surface finish for a given material removal rate.

The capabilities of conditioning and forming of ceramic grinding tools

“…Proces ten nazywany jest kondycjonowaniem. Niewłaściwie dobrane parametry kondycjonowania ściernicy mogą prowadzić do pogorszenia chropowatości szlifowanej powierzchni, powstania nadmiernych drgań, wzrostu wartości składowych sił szlifowania a w efekcie końcowym również do skrócenia okresu trwałości ściernicy [7,11].…”

Avaliação Da Integridade Superficial Do Aço N2711 Após Retificação Com Rebolo De Óxido De Alumínio

“…Segundo Malkin (2012) e Saad et al (2010), a predição dos valores de rugosidade pode auxiliar na correta escolha dos parâmetros de corte a fim de que o acabamento superficial desejado seja alcançado. Ainda segundo Malkin (2012), quando um dressador de ponta única é empregado ao longo da dressagem (afiação) do rebolo abrasivo, a rugosidade R a da superfície a ser obtida é dependente de duas constantes empíricas R 2 e x, da espessura de material não removido (h eq ) e, da largura de atuação do dressador (b d ), profundidade de dressagem (a d ) e do grau de recobrimento do rebolo (U d ), Eq.…”

An experimental study of the effects of dressing parameters on the topography of grinding wheels during roller dressing

“…The dressing process can be performed in a number of ways including traditional techniques of single point and roller dressing, as well as more recent methods such as Electrolytic in-process dressing (ELID) and Laser [2]. Saad et al [3], who examined both point and roller dressing, highlighted the influence of overlap ratio on component surface finish. For this investigation roller dressing was studied due to its common use in industry when form grinding for aerospace component applications.…”
