    • Abstract
  • In order to measure male thread efficiently,vertical projection measurement method was studied in theory and experiment.The reason and conditions for the distortion of thread profiles in process of measuring profile angles was explained taking tri-angular thread and acme thread as examples.It is proved in principle that thread profile distortion cannot occur in measuring tri-angular thread profiles with vertical projection measuring method,while it does for acme thread.After comparing the measurement data of tri-angular thread and acme thread that measured with tool microscope and image instrument respectively,it shows that tri-angular and pipe thread can be measured properly with vertical projection measurement,and it can bring about big error for acme thread measurement.The result is helpful to measure male thread efficiently with vertical projection measurement.
