This paper describes the use of computer-aided measurement for external metric screw threads.Thread parameters,including thread pitch,thread angle,pitch giameter and major diameter,were measured with CCD cameras and image analysis software.New technologies such as digital image processing were used to increase the efficiency of measurements.In this study,by reconstructing the toolmaker‘s microscope,the computer-aided semi-automated measuring system was developed,which could evaluate the accuracy of screw thread fpofile.It is concluded that the measuement accuracy is comparable to that of traditional toolmaker‘s microscope method. 相似文献
