This is the form tolerance value for a cylindrical workpiece. Radial total runout refers to the degree of deviation of the cylindrical surface of a cylindrical workpiece from an ideal cylindrical surface at various points. I’m not sure if I’ve made myself clear this way. You can ask your colleagues who work in mechanics around you
The minimum radius difference between the concentric cylinder coaxial with the reference axis and encompassing all points on the surface, when the element under test rotates one full revolution around the reference axis
Thanks, it seems like you can do anything! What is your job?
I used to work on centrifugal pump design (technical aspects), and now I am responsible for pre-sales support and after-sales service.
Place a dial indicator on the shaft; as the shaft rotates one full turn, the value displayed on the indicator represents the amount of play
Total runout is the sum of the surface shape tolerance and the coaxiality position tolerance
I have a question: I use a bracket to support the shaft, and a magnetic base to fix the dial indicator. When the shaft is rotated by one full turn, the maximum reading on the dial indicator represents the circular runout at a certain point on the shaft. Is this value also the total runout? The symbols used to represent these two values are different. Please give some guidance. Thank you
