in the process of mechanical processing, the demand for the surface texture of the parts is becoming more and more high, not only exquisite but also good quality, so it is very important to detect the surface texture defects of the machined parts. This means to improve the level of automatic production and processing, and also to provide a basis for the work after the parts.

    there will be a lot of time series in the process of machined . If there is a processing defect in the time sequence, it is easy to cause defects in the surface texture of mechanical parts, but because the processing tools and processing methods are different, there may be a variety of forms and forms. Different texture, this not only affects the appearance, but also brings some influence to the precision of the parts.
    there are many textures on the surface of the mechanical parts, and many textures are defective. To find defects and compensate for the defects, it is very helpful to improve the precision of the parts. The detection in the surface texture detection system of the parts can be carried out in the following aspects:

    (1) test the surface principle of machine parts with some device methods

    (2) input the detected information into the computer so that the computer can process

    (3) computer system through signal processing programming spectrum image
