Abstract
Abstract Article describes the usage of multi-criteria analysis of drag finishing in order to determine the optimal parameters of the process on a prototype device for edge preparation. The prototype device was based on a 3-axis milling center and the drag finishing media used was Al2O3 granulate. Tools for the experiment were manufactured on a tool grinding machine Reinecker WZS 60 from the cemented carbide rod. After that, the tools were drag finished. Then, cutting edges radii were measured on a Zeiss SURFCOM 5000 surface and form measuring machine. The effect of process parameters such as spindle rotation speed, feed rate and time of the drag finishing on the size of the cutting edge radius and shape was examined. The experiment design was described as well as measurement and evaluation of the output values through multi-criteria analysis in the Minitab software. The results of the multi-criteria optimization were summarized and compared. Purpose of the experiment and multi-criteria analysis described in this article was to determine the influence of process parameters on the cutting edge radius sizes when drag finishing the carbide tools – special carbide milling tools
