The Study of Parameters of Surface Roughness by the Correlation Analysis

The paper deals with evaluation of relation between individual parameters of roughness of the blasted surfaces by the correlation analysis. Based on the measured values on the surfaces which were blasted by various types of blasting devices, the correlation matrix was set and the standard of statistic importance of correlation between the monitored parameters was determined from it. The correlation coefficient was also set.

Production Segmentation Using Hierarchical Methods of Cluster Analysis

Article is directed to segmentation of production using hierarchical methods of cluster analysis. Analysis is performed in statistical software STATISTICA. The result of clustering process are segments of products and machinery in form of arranged machine-product matrix. These data may serve for changing the disposition of workplace toward to manufacturing cells.

Modification of surface morphology of Ti6Al4V alloy manufactured by Laser Sintering

Abstract The paper deals with the evaluation of relation between roughness parameters of Ti6Al4V alloy produced by DMLS and modified by abrasive blasting. There were two types of blasting abrasives that were used – white corundum and Zirblast at three levels of air pressure. The effect of pressure on the value of individual roughness parameters and an influence of blasting media on the parameters for samples blasted by white corundum and Zirblast were evaluated by ANOVA. Based on the measured values, the correlation matrix was set and the standard of correlation statistic importance between the monitored parameters was determined from it. The correlation coefficient was also set.
