Paragraph starter

The challenge of achieving uniform surface finish on free-form surfaces during ball-end milling is significant, as varying surface inclinations alter the effective tool diameter and thus cutting conditions. Research by Mgherony and Mikó (2024) proposes an innovative algorithmic approach to tool path planning that actively minimizes these diameter variations. By guiding the tool towards points with anticipated minimal changes in working diameter, this method promotes more consistent cutting speeds and a homogeneous machined surface, offering a valuable strategy for improving the quality of manufactured complex components.
