ABSTRACT:
A device and method for checking the roundness of ball-point type contacts associated with a measuring device and used to engage a threaded surface of a specific thread type to facilitate measurement of critical dimensional parameters of a threaded member. The device consists of a hard, wear resistant, and dimensionally stable material having formed thereon a reference groove and a comparison groove adjacent flat surfaces. The reference groove conforms in profile to the profile of the thread type while the comparison groove is square-shouldered and wider than deep. The depths of the reference and comparison grooves are selected such that a perfectly round ball-point type contact is insertable into each to the exact same depth relative the respective adjacent surfaces. The method requires attachment of the contact to a dial gage capable of measuring the distance to which the contact extends below a reference plane. Inserting the ball-point type contact first into the reference groove, zeroing the device and then checking for any deflection of the dial when the ball-point type contact is inserted into the comparison groove enables a quantitative determination of the amount of wear to the spherical surface to be made.
