Magnetic properties are known to be crucial in the application of electrical steel and they
are therefore covered by manifold studies. Other ferromagnetic materials are out of scope in this
respect, even if the importance of magnetism of conventional steel is evident. Additionally, there
is a contradiction regarding the major influence on magnetic properties. Machining, transport, and
storage are possible influencing variables. In the experimental investigations, specimens consisting
of the bearing steel 100Cr6 are machined by turning and partly by subsequent diamond smoothing.
While machining using several cutting speeds and smoothing forces, the thermoelectrical voltage,
current, and the components of the resultant force are recorded. The results show how the nearsurface plastic deformations evolve throughout the machining process. Additionally, it was found
that the magnetic properties and other properties of the surface layer are influenced in different
ways depending on turning and diamond smoothing parameters. Correlations between in situ
and ex situ measured values are shown. This study aims to solve the aforementioned question by
quantification of machining impacts of cutting speed in turning and force in diamond smoothing
and its dependence on transport and storage
