Digital Test Instrument of Radial Direction Displacement Precise for Round Shape Part Based on Labview

In the past, the instrument in the test station is usually using analogy technology, the testing and inspecting with the device executed with discrete and isolated way, in order to improve the efficiency and effectiveness, the digital instrument of radial direction preciseness for round shape part is designed and composed based on Labview in this research. The mechanic section of this instrument is an inspection device, the acquisition section use the acquisition module of NI, the software of the instrument is developed with Labview. The instrument is fitted to apply in the shop floor of factory.
