Abstract: Introduces the technique of virtual instrument and the software development platform LabWindows/CVI and discusses the basic principles and mathematical models for developing the cylindricity error virtual measuring instrument with the sampling technique involved. The probe-to-probe error separation method was adopted in design to lower greatly the mechanical precision required for the virtual measuring instrument. The conceptual design and an example of developed virtual measuring instrument are described, as well as the application of OpenGL to the virtual measuring instrument. The soft panel designed for the virtual measuring instrument can display a three-dimensional graph of cylindricity error, thus providing a basis on which the cause of the error and the way to control it are both available.
