5020a FMT Formation à la Métrologie Tridimensionnelle : Vé 2trous 3Pl+2Ce

Introduction

This tutorial provides a comprehensive guide to the 3D metrology training focused on locating two holes using geometric specifications. This process is crucial in various fields, including aerospace and quality assurance. This guide will help you understand the practical application of 3D metrology through a specific example.

Step 1: Understanding Geometric Specifications

• Familiarize yourself with the concept of geometric specifications, which define how parts should be measured and what tolerances are acceptable.
• Review the provided example file, which can be accessed via this link.
• Make sure to understand the basic terms related to geometric tolerances, such as:
  • Flatness
  • Perpendicularity
  • Position tolerance

Step 2: Setting Up the Measurement Environment

• Ensure you have the necessary equipment for 3D measurement, such as a coordinate measuring machine (CMM).
• Prepare the measurement area by:
  • Clearing any clutter
  • Calibrating your equipment according to manufacturer specifications
• Check that the environment is stable (temperature and humidity) to avoid measurement errors.

Step 3: Locating the Holes

• Use the CMM to locate the specified holes on the object.
  • Start by identifying the reference points on the part.
  • Measure the coordinates of the first hole using the CMM probe.
  • Record the position and repeat for the second hole.
• Ensure that the measurements adhere to the geometric specifications outlined earlier.

Step 4: Analyzing the Measurements

• Compare your measured coordinates to the specified geometric tolerances.
• Use software to visualize the measured data against the design specifications.
• Document any discrepancies and assess whether they fall within acceptable limits.

Step 5: Reporting the Results

• Compile your findings in a structured report, including:
  • Overview of the measurement process
  • Measured coordinates and any deviations
  • Conclusions on the quality of the part based on the specifications
• Reference any resources or tools used during the measurement process.

Conclusion

In this tutorial, you learned how to apply geometric specifications to locate and measure holes using 3D metrology techniques. By following these steps, you can ensure accurate measurements that conform to industry standards.
