Checking form and position tolerances is one of the most important measures to be carried out in many manufacturing processes. These checks have a major impact on part functionality and manufacturing costs. For precision parts in particular, the permitted deviations are becoming ever smaller, with tolerances in the micrometer range.
These deviations from the ideal dimensions calculated by the designer are commonplace, and the challenge is to keep them within the permitted tolerances.
In the metrology room or on the shop floor, misinterpretations can have serious consequences for part quality, and therefore for the entire production process.
Obtaining a reliable result involves complex measurements, with important precautions to be taken when evaluating results and deciding on the best measurement strategy.
The Accretech guide "Understanding Form Measurements" shows quality managers or production staff how to meet this challenge when measuring form and position tolerances.
This document by Accretech experts provides an overview, detailing which tolerances are relevant, how these tolerances are measured, what needs to be taken into account when measuring, and what technologies are available to do this.
The guide details the fundamental principles of shape measurement, the main causes of errors and the means available to avoid them:
- The most important geometric tolerances
- An overview of reference calculations
- Identify and avoid the causes of measurement errors
This short book is a useful tool for avoiding typical errors that are detrimental to quality assurance, and for optimizing measurement results.
