| Abstract: | In this paper, measurement of non straightness of barrels is given out by using the system made up of photo electrical position sensor PSD (position sensitive device), semiconductor laser, data acquisitive card and microcomputer. The repeated experiments proved this method, compared with the conventional manual data acquisition, has higher accuracy(<0.1mm), greater speed of measurement and process, more automatic, simpler fixation and adjustment, etc. The detailed principle of tangent method of 3D curvature and the ways to improve accuracy are also discussed. In the end, the measurement results of non straightness of barrel with 37mm inside diameter are provided as well. |
