Machine readable medium and method for determining feature-relating tolerance consumed

A machine-readable medium for programming a computer to determine feature relating tolerance consumed for a plurality of manufactured holes on an object, said medium comprising processor executable instructions for

• determining a true position for each of said plurality of manufactured holes;
• determining a center for each of said plurality of manufactured holes;
• superimposing each of said true positions to form a one true position;
• determining the centers of each of said plurality of manufactured holes relative to said one true position;
• determining a circle that intersects or contains each of said centers;
• determining the diameter of said circle;
• determining feature relating tolerance consumed from said diameter.

A machine-readable medium for programming a computer to determine feature relating tolerance consumed for a plurality of manufactured features on an object where at least one additional feature is added to a pattern of features, said medium comprising processor executable instructions for

• determining a true position for each of said plurality of manufactured features;
• determining a location for each of said plurality of manufactured features;
• organizing each of said true positions into a single association;
• organizing the location of each of said plurality of manufactured features relative to said single association;
• determining a first circle that intersects or contains each location;
• determining the location of said additional feature;
• determining if the location of said additional feature is contained within said first circle;
• determining a second circle that intersects or contains said plurality of manufactured features and said additional feature, if said additional feature is not contained with said first circle;
• determining the diameter of said second circle;
• and
• comparing the diameter of said second circle with said feature relating tolerance to determine acceptability of the pattern.

A machine-readable medium for programming a computer to determine whether a pattern of features violates a pattern locating tolerance for a plurality of manufactured features on an object, said medium comprising processor executable instructions for

• determining a true position for each of said plurality of manufactured features;
• determining a center for each of said plurality of manufactured features;
• organizing each of said true positions into a one true position;
• organizing the center of each of said plurality of manufactured features relative to said one true position;
• determining a departure circle about each of said centers;
• and
• determining where said departure circles lie relative to a pattern locating tolerance circle.

A system in a manufacturing site, said system comprising a computer and a coordinate measuring machine adapted to determine whether a pattern of manufactured features violate a pattern locating tolerance, and adapted to determine feature relating tolerance consumed for said pattern of features, said system adapted to perform the steps of

• determining a true position for each of said plurality of manufactured features;
• determining a center for each of said plurality of manufactured features;
• organizing each of said true positions into a one true position;
• organizing the center of each of said plurality of manufactured features relative to said one true position;
• determining a departure circle about each of said centers;
• determining if any of said departure circles lies outside a pattern locating tolerance circle to determine if said pattern locating tolerance is violated;
• determining a circle that contains each of said departure circles;
• and
• comparing a diameter of said circle to said feature relating tolerance to determine acceptability of the pattern.
