Abstract
A method assesses the beam profile of a light beam of a non-contact tool setting apparatus, the apparatus including a transmitter for emitting the light beam and a receiver for receiving the light beam. The receiver generates a beam intensity signal describing the intensity of received light. The apparatus is mounted to a machine tool having a spindle that is moveable relative to the non-contact tool setting apparatus. The method includes loading an object having an edge into the spindle of the machine tool and using the machine tool to move the spindle relative to the apparatus so that the edge of the object passes through the light beam. The beam profile of the light beam is then determined using the beam intensity signal generated at a plurality of positions during the step (ii) of moving the edge of the object through the light beam.
