Se utilizan para verificar y calibrar la exactitud y comportamiento de las mediciones efectuadas en las aplicaciones industriales. Implementing and sustaining the dimensional management process requires a major investment in time, personnel, and money at the early stages of a design. If top management is not willing to make and sustain its commitment to the program throughout its life cycle, the program will fail. Capability refers to the total variation within the process compared to a six standard deviation spread.


Metrologia Breve resumo sobre Metrologia. Key characteristic identification is a tool for facilitating assembly that will reduce variability within the specification limits. Metrologia de Masas 1. The sponsoring editor apkstila this book was Linda Ludewig, and the production supervisor was Pamela Pelton. The higher the Cp value, the less variance there is in the process for a given tolerance.

A continuous program of gage and tooling verification and certification must also be integrated within the framework of the dimensional measurement plan. The typical steps in performing a simulation study using simulation software are listed below see Fig.

Statistical process control is a tool that uses statistical techniques and control charts to monitor a process output over time. However, key characteristic identification does not diminish the importance of other nonkey features that still must comply with the quality requirements defined on the drawing. 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.


To reduce rework, the process spread should be centered between the specification limits and the width of the process spread diimensional be reduced. Therefore, no dimensional management program should begin until program directives from upper management clearly declare that sufficient personnel, budget, and other resources will be guaranteed throughout the mertologia of the dimsnsional.

If the objectives cannot be agreed upon by a consensus of the dimensional management team, the program cannot proceed to defining the design concept. These stages integrated with the various dimensional management tools can be represented by a flow diagram see Fig. Using the functional assembly model, a 3-D assembly tolerance analysis is statistically performed to identify, rank, and correct critical fit and functional relationships between the mating parts that make up the assembly.

The actual location of these tooling points must then be periodically checked and validated to ensure that they have not moved and are not introducing errors into the product.

Or contact your local bookstore. This will ensure that the proper fit and function between mating parts has been obtained. Son los errores relacionados con la destreza del operador Error de paralelaje: Metrologia legal no brasil Funcionalidade do trabalho no Brasil.

After key characteristics have been defined and process and tooling plans have been developed, parts must be measured to verify conformance with their dimensional specifications.

The results appstila represent reality because the simulations are based on statistical concepts taking into account the relationship between functional requirements as well as the expected process and measurement capabilities.

Control charts are line graphs that are commonly used to identify sources of variation in a key characteristic or process. Dimensional Management A standard deviation is a unit of measure used to describe the natural variation above an average or mean value. SITE To ensure the functioning of the site, we use cookies. This measurement data must be collected and presented in a format that is concise and direct in order to identify actual part variation. Por lo tanto, ser trazables a patrones nacionales e internacionales.


The higher the Cpk value the less loss is associated with the variation. The dimensional management process can be divided into four general stages: A key characteristic is a feature of an installation, assembly, or detail part with a dimensional variation having the greatest impact on fit, performance, or service life.

Existen muchas formas de expresar la Incertidumbre de medida Conceptos derivados o asociados: The implementation of a key characteristic system has been shown to be most effective when the key characteristics are:.

The identification of key characteristics for a specific product is the responsibility of the dimensional management team working very closely with the customer. A standard deviation is a unit of measure used to describe the natural variation above an average or mean value.

They can be used to reveal a problem, quantify the problem, help to solve the problem, and confirm that corrective action has eliminated the problem. Cpk can be used to measure the performance of a process.
