Notch wear
A mechanical wear which is concentrated at
the depth of cut. This wear reduces the tool
life drastically and produces a burr on the
component.
Remedy: It is an application related wear
which is easiest solved by changing the
entering angle (insert shape) rather than
insert grade.
Abrasive wear
Mainly caused by the hard particles in the
workpiece material rubbing or grinding the
edge.
Crater wear
Formed through the tool material being
removed from the chip face by the hard
particle grinding action.
Remedy: Select a positive insert geometry.
Reduce the speed to obtain a lower
temperature.
