Automatic inspection system for dimensional measurements of the saw blade milling cutter
Abstract: The demand for
measuring equipments of automatic optical inspection has grown rapidly, because
of its benefits of promoted efficiency and higher precision. Instead of manual
projection measurements, measurement performance and efficiency can be
obviously enhanced by the image measurement system. In this investigation,
digital image processing and geometrical measurement principles have been
integrated to develop a dynamic measurement system for the dimensional
measurements of a saw blade milling cutter. The repeatability of the
measurement system has been analyzed and its accuracy has been verified by
using commercial 3D image measurement system. The analysis results show that
the dimensional precision of 25μm and the angular precision of 0.21° can be
realized by the self-developed measurement system. Between the results of the
developed system and reference standard system, there are 25μm deviation in
dimensional measurement and 0.26° in angular measurement. That measuring
performances can meet the industrial requirement and the higher measurement
efficiency can be achieved.
