HFC nástroje malých průměrů pro obrábění hlubších dutin a zápustek

Abstract

This diploma thesis focuses on the technical evaluation of high feed cutters (HFC) from Dormer Pramet and Moldino. The aim of the study was to experimentally assess and compare the performance of individual cutting tools based on functional tests and durability assessments. The evaluation concentrated on surface roughness, spindle load, and insert wear during the machining of tool steel X38CrMoV5. The theoretical part provides an overview of high feed milling principles, methods for measuring surface roughness, cutting forces, and tool wear. The experimental part was carried out on the vertical machining center MCV 1270 Power, where various combinations of cutter bodies and indexable inserts were tested under defined cutting conditions. The results revealed differences in tool performance and their suitability for specific machining applications.
