Abstract
A method and system for determining a tool center point (TCP) for a beam tool involves the use of a specially design aperture and light sensing device. The method and system oscillates the beam tool across an aperture assembly such that light from the tool periodically passes through the aperture assembly. Center point coordinate information is then determined based on passage of light through the aperture assembly. The method and system further provides for calculating the TCP based on the center point coordinate information.
