  • Method for determining a dimension between the back and the cutting edge of a vibrating blade mounted on a cutting tool
    Patent number: 11224953
    Abstract: A method for determining a dimension between the back and the cutting edge of a vibrating blade mounted on a cutting head includes successively of acquiring a digital image of the blade mounted on the cutting tool so a line corresponding to a cutting edge of the blade and a line corresponding to a back of the blade are visible in the image, determining on the digital image along a straight line perpendicular to the line corresponding to the cutting edge of the blade the pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade, and calculating a filtered dimension between the back and the cutting edge of the blade from the number of pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade.
