[Display omitted] •New parameters for assessing of abrasive tools have been defined.•Parametric model of three different types of grinding wheels has been established.•Sensitivity to wheel type and wear in the parametric model was tested.•The sensitivity of the new parameters to machining potential has been identified.•The new parameters are closely related to machining potential of the abrasive tool. This paper presents a methodology for assessing the state of the active surface of abrasive tools using new parameters that characterize their machining potential. The new parameters were defined in consideration of the features of abrasive tools, which resulted from the variability of the arrangement of the ridges of abrasive grains and the diversity of their shape and orientation. A detailed analysis was performed to determine the impact of the protrusion, sharpness, and cutting edge orientation of abrasive grains on the value of two new assessment parameters: the surface indicator of height and sharpness of protrusions (Shs) and the surface indicator of height, orientation, and sharpness of protrusions (Shos). Based on the experimental results, the state of the active surface of abrasive tools was analyzed using topography parameters in accordance with ISO 25178-2 (ISO 25178-2:2012, 2012) and the new assessment parameters. The new parameters enabled the characterization of the machining potential of active grains.
