ABSTRACT:
This invention involves an indicator assembly and method for locating the position of the axis of a cylindrical workpiece in a roll turning lathe in order to allow accurate adjustment of the workpiece axis position into alignment with the turning axis of the lathe. The assembly is removably mounted on the tool slide of the lathe for radial movement into engagement with the workpiece, and is constructed to locate the relative position of the workpiece and machine axes in horizontal and vertical coordinates. This apparatus is used in the method to compare the position of the cylindrical surface of the faceplate of the lathe with the position of the surface of the journal of the roll in the horizontal coordinate and to compare the position of the axis of the faceplate with the position of the axis of the journal in the vertical coordinate.
