Abstract
An edge finder held on the end of a spindle of a milling machine is provided with a flat on the outer cylindrical surface of the working end member thereof. When the edge of a work piece mounted on the table of the milling machine is slowly advanced by a machinist to contact the rotating end member, the flat thereon produces an audible clicking sound each revolution of the spindle. Moreover, upon contact, the flat on the rotating working end member causes it to vibrate radially thereby enhancing the sidewise jump thereof and making it easier for the jump to be observed by the machinist.
