Wheel dressing is an important action in the grinding process. This paper reports on the comparative study of the performance of two types of diamond dresser tool measured in terms of ground surface roughness. For experiments were used two types of dressers, single point and multi-point diamond dresser. In addition to the dresser tool, the wheel dressing speed and dressing depth were taken into account as dressing variables. Cutting conditions were a constant; the results of dressing were observed for bearing steel 100Cr6. The experimental study was designed using an orthogonal array and experimental data were processed by the analysis-of-variance method (ANOVA). The results show that with a 95% confidence, dressing with a multi-point diamond tool results in a smoother ground surface than with a single point diamond tool. As expected, wheel dressing speed and dressing depth also have significant effects on surface roughness. However, wheel dressing speed is much more influential than dressing depth.
