Study on the Virtual Instrument for Coaxiality Error

Article Preview

Abstract:

Used LabWindows/CVI as software platform, existing apparatus in laboratory and a data acquisition card as hardware platform, the virtual instrument for coaxiality error was developed. It combines the theory to measure form and position error with technology about virtual instrument. Coaxiality error by least square method and the minimum zone method is measured. The image of coaxiality error can be displayed on the screen to analyse the causes of error, so as to control the manufacturing error. The virtual instrument has the advantages of high precision, stablity, low manufacturing cost, especially the excellent function expandability. It can be used for experimental teaching and the actual production.
