| Abstract: | The instrument was developed on the newest virtual instrument platform. Lab Windows/CVI of American national instruments was used to be software platform, Data acquisition card and equipment of laboratory was used to be hardware platform. It was integrated form and position error measuring technology with virtual instrument technology. The cylindricity error is evaluated by least square method, minimum zone method. The cylindricity error chart is able to display in the screen in order to analysis the cause of cylindricity error. The cost of the instrument is low. The instrument is stable and reliable. The instrument function can be enlarged. It can be used in both laboratory and industry. |
