An apparatus and method is described for inserting pins in holes wherein either the pin or the hole is chamfered or beveled. One part is vibrated with respect to the other in a plane orthogonal to the direction of insertion. One part is incrementarlly moved in the direction of insertion. When interference caused by the contact is sensed, the magnitude of the interference is determined and used to reposition the center-line of the one part in the orthogonal plane until the pin is fully inserted.
