The apparatus for normalization of a drilling tool to a work surface
includes a light source, a beam splitter, and a screen. The beam splitter
directs and the screen receives at least a portion of the light reflected
off of the work surface. When the received light is located in a
predetermined portion of the screen, then the drilling tool is normal to
the work surface. The method for normalization of a drilling tool to a
work surface includes positioning the drilling tool proximate the work
surface, transmitting light toward the work surface, creating an image of
the light that has reflected off of the work surface upon a screen,
thereby permitting the orientation of the drilling tool to be adjusted
until the image of the reflected light is located in a predetermined
portion of the screen that is indicative of proper alignment.
