Design of Integrated Quality Detect System for Saw Blades Based on LabVIEW

In order to solve the problem of low efficiency and poor precision which usually appeared in saw blade detection, here designed a system that can detect the surface jump, thickness, warpage and cracks at the same time. Laser displacement sensors were used to ensure the accuracy. The saw blade was driven by a stepper motor, which is used to avoid direct manipulation of the blade by the user's hands By using eddy current test, cracks could be accurately detected. The human-machine interface (HMI), designed based on LabVIEW, could not only did the data processing, but also had an easily interface. Test data could be stored in the database for further analysis. The system has the characteristics of fast detection speed, high precision, good safety, thus can replace the traditional method of saw blade detection.
