Se establecen7 magnitudes fundamentales, con los patrones para medirlas: A key characteristic apstila a feature of an installation, assembly, or detail part with a dimensional variation having the greatest impact on fit, performance, or service life.

Metrologia legal no brasil Funcionalidade do trabalho no Brasil. Paul resides in Richardson, Texas, with his wife Jane and their three children.

The key factor in the success of a dimensional management program is the commitment and support provided by upper management. The identification of key characteristics for a specific product is the responsibility of the dimensional management team working very closely with the customer.

Incrivelmente absorvente do primeiro ao The sponsoring editor of this book was Linda Ludewig, and the production supervisor was Pamela Pelton. Cpk is a ratio that compares the average of the process to the tolerance in relation to the variation of the process.

Your consent to our cookies if you continue to use this website. Cp and Cpk values are simply indicators of progress in the effort to refine a process and should be continuously improved.

The typical steps metrologja performing a simulation study using simulation software are listed below see Fig. It does not assume that the process is centered. Dimensional management tools have been successfully incorporated within commercial 3-D simulation software see Chapter This center develops and deploys dimensioning and tolerancing best practices within Raytheon.


A standard deviation is a unit of measure used to describe the natural variation above an average or mean value. Por ejemplo, la unidad fundamental de masa en el Sistema Internacional SI es el kilogramo.

Hill nor its authors guarantees the accuracy or completeness of any information published herein and neither McGraw-Hill nor its authors shall be responsible for any errors, omissions, or damages arising out of use of this information. Tiene por objetivo el estudio de los sistemas de medida en cualquier campo de la ciencia.

Es el error propiamente de los instrumentos no calibrados. This capability is the amount of variation that is inherent in the process. Using information from the CAE database, a functional assembly model is mathematically defined and a definition of assembly sequence, methods, and measurements is created.


A continuous program of gage and tooling verification and certification must also be integrated within the framework of the dimensional measurement plan. Remember me Forgot password? This can be accomplished by using key characteristics to identify features where variation from nominal is critical to fit and function between mating parts or assemblies.

This will ensure that the proper fit and function between mating parts has been obtained. This work is published with the understanding that McGraw-Hill and its authors are supplying information but are not attempting to render engineering or other professional services. El grado de exactitud es la mitad de la unidad de medida. If such services are required, the assistance of an appropriate professional should be sought.


Cuando expresamos la exactitud de un resultado se expresa mediante el error absoluto que es la diferencia entre el valor experimental y el valor verdadero. Dimensional Management A standard deviation is a unit of measure used to describe the natural variation above an average or mean value. However, key characteristic metgologia does not diminish the importance of other nonkey features that still must comply with the quality requirements defined metrolpgia the drawing.

Dimenslonal can be used to measure the performance of a process.
