Machining is a method that stands out among the
production techniques to give the desired final shape to
metal parts and to ensure perfect connections with each
other at their points of use. The most important factor
determining the process quality of machining, which is
frequently used as a finishing process in production, is the
quality of cutting tools. The tools with a limited service life
due to factors such as wear and fracture, it creates a
significant amount of expenditure. In addition, it is
necessary to examine the problems that occur in the inserts
due to reasons such as any failure affects the inserts also
affects the pieces. Failure mechanisms that occur in inserts
should be examined in order to determine tool life, to
prevent any problems that may arise in the machined piece
and to reduce the additional cost. In the literature, there are
generally studies on the failure analysis of a certain factor
on a piece. In the present study, the general failures that
may be encountered on the inserts during the milling
process, the mechanisms that cause failure and the
recommendations to prevent this failure were mentioned.
Milling inserts that examined in the study were obtained
from Bor Cutting Tools Machine Industry Trade Ltd. Co.
Examinations on the inserts were made using a Scanning
Electron Microscope (SEM). In general in this study were
observed different modes of cutting tool failure including
plastic deformation, rake face wear, flank wear, chipping,
abrasion and breakage.
