Mechatronic System for Automatic Inspection of Circular Saw Teeth

Abstract:

The paper presents a mechatronic system for automatic inspection of circular saw teeth. The described system, based on numerical processing of recorded tooth images, has been implemented in the automatic vision controller system WKOPTar. The applied mechatronic system for the automatic spindle control positioning guarantees for the circular saw blade teeth a proper position enabling to grab and record tooth images even for non-uniform pitches in the examined circular saw blade. Some examples of measurements and geometry analyses of circular saw teeth were provided in order to illustrate the diagnostic usability of the apparatus. The system allows the user to determine up to 32 parameters for one tooth. However, the direct interpretation of physical parameter is sometimes partially limited by the software because the same parameter might have different meaning. Thus, in some cases a proper interpretation of the results may be feasible after recorded tooth screen analyses.
