The investigation described in this paper resulted in some complicated statistical analysis.
The first level was an experimental design with technological parameters as factorials input and
geometrical surface layer properties as quantitative outputs. The second level was an analysis
generally leading to an optimization inverse problem: what parameters result in desired surface
layer properties. The principal component analysis was made to identify possibility of a
dimensionality reduction and simplify the optimization. Obtained results showed that the
experimental dataset is practically two-dimensional but PCA projection involves all factors into the
skewed hyper-plane. This paper contains a description of the problem, obtained results, analysis and
conclusions.
