Evaluation of Classification Ability of the Parameters Characterizing Stereometric Properties of Technical Surfaces

Kacalak W., Różanski R., Lipiński D.

Journal of Machine Engineering

2016

Vol. 16, No. 2

86--94

The analysis of classification ability of the parameters used for the description of surfaces formed during the processes of technological processing constitutes important issue in the surface layer metrology. To investigate the classification ability, variance and geometric mean of the ordered differences of the parameter value. The study compares behaviour of both indices for different distributions of ordered differences of the parameter value. Moreover, the relationship between bot indices and influence of the number of minor differences of the parameter value on the value of variance and geometric mean.
