The Influence of Copy Strategy on the Tool Life of Ball End Mills and Achieved Surface Roughness

Abstract:

The article deals with the tool life of ball nose end mills and surface roughness of steel C45 depending on up-copying and down-copying. The cemented carbide and high speed steel was used as tool material. Furthermore, the new and sharpened cutting tools were also compared. In the experiment, the cutting speed, feed rate, axial and radial depth of cut were not changed. The results show different achieved surface roughness of machined material C45 and tool life of ball nose end mills depending on the copy milling strategy for various tool materials.
