Coated carbide cutting tools performance in high speed machining processes

Abstract EN

High-speed machining (HSM) has emerged as a key technology in rapid tooling and manufacturing applications.

The present work studies the effect of cutting parameters (cutting speed, feed and depth of cut) in turning process applied on C-60 steel using multi- coated carbide cutting tools at high cutting speeds.

The influence of cutting parameters on a cutting forces, tool wear and surface roughness are analyzed.

The importance of orthogonal force components to surface finish and tool wear are explored.

The results show that cutting forces has a very strong correlation with surface finish and that increased spindle speeds lead to far superior surface finish.

Tool wear measurements demonstrated the capability of such coated carbide tools in turning steel with reasonable low tool wear (i.e.

high tool life).

Forces measured resulted in relatively low values.

The cutting component (Fc) is the largest of all.

For the different cutting conditions studied, the feed rate has the greatest influence on force and tool wear.
