The correct selection of cutting parameters is crucial to provide tribological conditions that contribute to meet the required workpiece surface topography characteristics, especially considering abrasive processes such as grinding. The present work sought to evaluate the influence of several cutting parameters on surface topography of Inconel 718 after grinding. Surface finish and morphology were used to assess topography of workpiece. Cutting forces and coefficient of friction were also analyzed. The results showed that, although workspeed promoted negligible effects, varying depth of cut and wheel speed strongly affected tribological conditions at contact zone, resulting in significant changes on topography. Reducing abrasive grit size improved surface finish and resulted in Rsk close to zero.

正确选择切削参数对于提供有助于满足所需工件表面形貌特征的摩擦学条件至关重要，特别是考虑到磨削工艺（例如研磨）。本工作旨在评估磨削后几个切削参数对Inconel 718表面形貌的影响。使用表面光洁度和形态来评估工件的形貌。还分析了切削力和摩擦系数。结果表明，尽管工作速度的影响可忽略不计，但切削深度和轮速的变化会严重影响接触区的摩擦学条件，从而导致形貌发生重大变化。减小磨料粒度可改善表面光洁度，并使Rsk接近零。
