Hereof, what is meant by runout?
Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. Radial run-out will measure the same all along the main axis. Axial run-out is caused by the tool or component being at an angle to the axis.
Secondly, how do you calculate circular runout? Circular Runout (feature = circle, datum = cylinder) should be something along the lines of 2X (Radial Offset of feature to Datum) + Circularity(Feature Circle). Seems like this would simulate the FIM of an indicator placed on the feature while rotating about the datum.
Correspondingly, what is the difference between circular runout and total runout?
What, then, is the easiest way to think of the difference between circular runout and total runout? Circular runout controls only a particular circular cross section of a part, while total runout controls the entire surface of the part.
What is the runout symbol?
GD&T Tolerance Zone: 2-Dimensional circular tolerance zone that is defined by a datum axis where all points on the called surface must fall into. The zone is a direct reference to the datum feature. Runout is the total variation that the reference surface can have when the part is rotated around the datum's true axis.
