Paper Abstract

As monitoring the abrasion of tools becomes more and more important during metal cutting, many research efforts have been made in this aspect. This paper proposed a new method that detect and measure it directly by digital image technology and developed a detecting and measure system based on digital image. It is prone to automatically disposed and to integrate with machining and control information. A new filter method that average many same size images when acquiring images is proposed. At the same time, a new edge detection way by wavelet transform is also proposed. A new wavelet function is given when selection wavelet functions, which describe gray change of images more availably, as well as may avoid the jamming of noise. The rule of three is proposed to calibrate this system in this paper, and calibration precision arrives at application requirement. Functions of the software of this system include acquiring and processing images, edge detecting and segmenting images, and measure and analysis images. Images of tools are acquired by camera and CCD and video card. It can automatically differentiate and pick-up available information of the original image, such as area and perimeter and width and length and the location of the center of the abrasion region, by image processing and segmenting.
