Abstract
An assembly line reliably produces articles assembled from at least two components by measuring critical dimensions of components destined to be assembled together as one particular article. A specified testable condition is predicted for the particular article by solving a regression equation previously ascertained from other assembled and tested articles having components with known critical dimensions. If the predicted testable condition is unsatisfactory, a rejection operation is performed so that any unacceptable article is prevented from being assembled or from being used.
Claims12
A dispositioning control system comprising:
- a sensor operable to sense a parameter of a first component on an assembly line;
- and
- a controller configured to respond to the sensed parameter by solving a stored regression equation dependent upon the sensed parameter to obtain an assembled article prediction, the controller further configures to produce a rejection command in response to the prediction satisfying a rejection criteria.
A dispositioning controller comprising:
- a memory;
- a program, resident in the memory, the program configured to respond to a sensed parameter of a component by solving a stored regression equation dependent upon the sensed parameter to obtain a processed component prediction, the program further responsive to an acceptance criteria compared to the processed component prediction to perform a rejection operation;
- and
- a processor operable to execute the program.
A dispositioning controller program product comprising:
- program configured to respond to a sensed parameter of a component by solving a stored regression equation dependent upon the sensed parameter to obtain a processed component prediction, the program further responsive to an acceptance criteria compared to the processed component prediction to perform a rejection operation;
- and
- signal bearing medium containing the program.
A method for assembling an article, the method comprising:
- accessing a regression equation for a testable condition of an article being assembled from a first component and a second component;
- sensing a parameter of the first component related to the testable condition;
- sensing a parameter of the second component related to the testable condition;
- solving the regression equation to determine a predicted testable condition of the article;
- and
- performing a rejection operation in response to the predicted testable condition satisfying a rejection criteria.
