COMPARISON OF CLASSIFICATION ABILITY INDICES OF PARAMETERS CHARACTERIZING THE STEREOMETRIC FEATURES OF TECHNICAL SURFACES
Journal Title: Journal of Machine Engineering - Year 2018, Vol 18, Issue 3
Abstract
The study examined the relationship between the values of two indices evaluating the classification capacity of parameters characterizing the stereometric features of technical surfaces. The values of 83 3D parameters characterizing the stereometric features for 22 surfaces created in various machining processes were taken into account. The examined surfaces differ significantly in the stereometric characteristics of the surface with the similar value of the St parameter. The variance and the geometric mean of ordered parameter values differences were used as the indices of parameters classification ability. In particular, the existence, type and strength of relationship between the adopted indices were evaluated, and the model of the relationship between the indices was determined using the least-squares method. A comparison of the results obtained with those obtained from the analogous evaluation for 8 types of theoretical distributions of parameter values was also carried out.<br/><br/>
