Abstract: In order to reduce the error in the surface wear detection of machined parts, improve the detection accuracy of the failure degree of parts and shorten the detection time, a method of surface wear detection of machined parts based on image processing is designed. Firstly, the wear mechanism is analysed and the mathematical model of wear law is established. Then, the relationship model of surface wear of machined parts is analysed to determine the range of wear data to be detected. Finally, three components are used to determine the grey level image of part surface wear, calculate the pixel value of the maximum grey level image, and then binary processing is carried out. The noise is removed by means of the mean filtering algorithm. Finally, the wear detection of machined parts is realised by calculating the weighted mean. The results show that the wear detection error of the proposed method is low and has credibility.
