Abstract
Determining of the starting and end positions of the machining programme of a gear making machine with respect to the axial position of the workpiece ( ) by means of a laser light line ( ) projected at right angles to the workpiece axis, the position of which light line relative to the reference point of the tool ( ) is known. By mutual displacement parallel to the workpiece axis, the light line ( ) and one or both of the workpiece end faces ( ) are brought to coincide. The axial positions thus obtained are transmitted to the machine control system. The determining of the axial tool position takes place analogously by the projection of a laser light line onto the circumference surface of the tool ( ) at right angles to the tool axis.
