Abstract

The thesis focuses on comparing the performance of a ball nose end mill and a barrel milling cutter in shaping an experimental component. The main objective is to compare the surface roughness measurements of machined surfaces using these two tools. The theoretical part describes both tools, followed by an explanation of surface structure and theoretical surface roughness derivation. The preparation of the practical section includes details of the machine used, tool holding, the parameters of the tools, and a brief description of the CAM software. In the practical part, the measured values of surface roughness and waviness are evaluated. The conclusion evaluates the effectiveness of using the barrel milling cutter compared to the ball nose end mill. The expectation is to achieve at least as good, if not better, results using the barrel tool. Additionally, an increase in work efficiency is anticipated with the use of the barrel tool while maintaining or improving surface quality within a shorter production time, as recommended by the manufacturer.
