In the paper is presented a study regarding the influence of different factors on the roughness of machined surfaces obtained by manufacturing process of flat grinding. The workpieces that were used on the experimental tests were radial bearing ring with needles made of steel hardened to 60-64 HRC. It were taken into consideration factors like, the size of the machined surface, the traverse speed, the grain size of abrasive grinding wheels, cutting fluid.
During the experiments was used the method of the Box-plot graphical representation that aims to observe and characterize the distribution of values obtained on these tests.
