Abstract:
A method of verifying the quality of a pressing operation of a press-fit part onto a receiving portion of a receiving assembly, the receiving portion being a pocket of the receiving assembly, the pocket having a depth defined by the distance between outer and inner surfaces thereof, the method comprising the steps of:first measuring a predetermined dimension of the press-fit part to establish a first measurement value; first directing a first measuring probe to the receiving portion of the receiving assembly onto which the press-fit part is to be pressed to produce a first measurement signal corresponding to a maximum depth of insertion of the press-fit part into the pocket of the receiving assembly; second directing a second measuring probe to the outer surface of the pocket of the receiving assembly to produce a second measurement signal; differential measuring a difference in the respective distances corresponding to the first and second measurement signals produced during the respective steps of first and second directing to establish a second measurement value; urging the press-fit part onto the receiving portion of the receiving assembly; third measuring a portion of the receiving portion of the receiving assembly that extends beyond a predetermined surface of the press-fit part to establish a third measurement value; first comparing the third measurement value against the difference between the first and second measurement values to form a first comparison value; and second comparing the first comparison value against a predetermined comparison value to determine the quality of the pressing operation.
