Resumen
[EN] In this work we propose a new online, low cost and fast approach based
on computer vision and machine learning to determine whether cutting tools
used in edge pro le milling processes are serviceable or disposable based on
their wear level. We created a new dataset of 254 images of edge pro le cutting
heads which is, to the best of our knowledge, the rst publicly available
dataset with enough quality for this purpose. All the inserts were segmented
and their cutting edges were cropped, obtaining 577 images of cutting edges:
301 functional and 276 disposable. The proposed method is based on (1)
dividing the cutting edge image in di erent regions, called Wear Patches
(WP), (2) characterising each one as worn or serviceable using texture descriptors
based on di erent variants of Local Binary Patterns (LBP) and (3)
determine, based on the state of these WP, if the cutting edge (and, therefore,
the tool) is serviceable or disposable. We proposed and assessed ve
di erent patch division con gurations. The individual WP were classi ed
by a Support Vector Machine (SVM) with an intersection kernel. The best
patch division con guration and texture descriptor for the WP achieves an
accuracy of 90.26% in the detection of the disposable cutting edges. These
results show a very promising opportunity for automatic wear monitoring in
edge pro le milling processes.
