ABSTRACT:
A novel, portable coordinate measuring machine comprises a multi-jointed (preferably six joints) manually positionable measuring arm for accurately and easily measuring a volume, which in a preferred embodiment, comprises a sphere ranging from six to eight feet in diameter and a measuring accuracy of 2 Sigma.+-.0.005 inch. (It will be appreciated that "Sigma" means "one standard deviation".) In addition to the measuring arm, the present invention employs a controller (or serial box) which acts as the electronic interface between the arm and a host computer. The coordinate measuring machine of this invention is particularly useful in a novel method for constructing a 3-dimensional map of a measurable quantity (such as temperature, coating, thickness, density or the like) using an independent transducer located at the end of the measuring arm.
