Performance and Wear Behaviour of Coated and Uncoated Cemented Carbide Tools during Milling of Titanium Alloys
(2022) MMTM05 20221Production and Materials Engineering
- Abstract (Swedish)
- Purpose – The purpose of this project is to study the performance of uncoated versus coated
cemented carbide tools when performing milling operations in heat treated titanium alloys,
with the goal of establishing a base line of knowledge and methodology linked to these
difficult-to-machine materials relevant for the metal cutting industry.
Design/methodology/approach – The work that is carried out in this project comprise both
literature review, that is presented as the state of the art as the necessary theoretical background
to understand what is done; and experiments, that were designed and executed at
Seco Tools in Fagersta in order to achieve the primary goal, testing and comparing different
scenarios where cutting parameters... (More) - Purpose – The purpose of this project is to study the performance of uncoated versus coated

to understand what is done; and experiments, that were designed and executed at
Seco Tools in Fagersta in order to achieve the primary goal, testing and comparing different
scenarios where cutting parameters played a key role.
Findings – The findings of this project have been broad; clear differences in performance in
some cases between coated and uncoated indexable tools, but also not significant differences
in some other cases between coated and uncoated versions; wear mechanisms acting over the
tools such as adhesion or diffusion; and other relevant findings linked to coating performance
and its morphology in the initial phases of contact between tool and workpiece.
Practical implications – The findings that have been made in this master thesis will contribute
to understand better how the wear mechanisms act over the tools when machining titanium
alloys, in order to be able to hopefully find a better cutting solution that would enhance tool
life in milling processes, creating more efficient and sustainable indexable cutting tools.
Research limitations – Machining time was the biggest restriction in terms of resource limitation,
as not all the experiments that were planned were finally executed due to this issue. (Less)
