Description:

Abstract:

A method of operating a coordinate measuring machine (CMM) provides the operator with the ability to automatically set the tolerance value of the part measurement based on preset conditions, and make an educated guess or estimate of the nominal part value during the measurement. This nominal estimation technique is based on the actual measurement value taken by the CMM, and the information supplied about the tolerance limits. This estimation technique of the present invention makes it much easier for the operator to measure the part and produce a report, since it significantly reduces the amount of operator keystroke information required to be manually input via the keyboard.
