Mitutoyo Optical Comparator Basics- Davis Technical College

Introduction

This tutorial provides a comprehensive guide on how to use the Mitutoyo Optical Comparator along with the QM Data digital readout. Understanding these tools is essential for precise measurement and inspection in machining and manufacturing processes. This guide will walk you through the key steps to effectively operate the optical comparator and utilize the digital readout for accurate measurements.

Step 1: Setting Up the Optical Comparator

• Position the Optical Comparator: Place the optical comparator on a stable surface, ensuring it is level to prevent measurement inaccuracies.
• Connect Power: Plug in the optical comparator and turn it on. Allow it to warm up for a few minutes before use for optimal performance.
• Adjust the Light Source:
  • Use the built-in light to illuminate the sample.
  • Adjust the brightness for clear visibility of the profile being measured.

Step 2: Preparing the Workpiece

• Select the Workpiece: Choose the part you want to inspect. Ensure it is clean and free of debris.
• Place the Workpiece on the Stage:
  • Secure the workpiece on the glass stage using the appropriate clamps.
  • Make sure it is positioned correctly for accurate viewing and measurement.

Step 3: Focusing the Optical Comparator

• Adjust the Focus:
  • Use the focus knob to bring the workpiece into clear view.
  • Ensure the edges of the part are sharp and distinguishable.
• Check the Alignment:
  • Make sure the workpiece is aligned with the crosshairs of the comparator for precise measurements.

Step 4: Using the QM Data Digital Readout

• Turn On the QM Data Readout: Activate the digital readout system.
• Select the Measurement Mode: Choose the appropriate mode for your measurement task (e.g., linear, angular).
• Take Measurements:
  • Use the measuring arm to probe the edges of the workpiece.
  • Read the measurements displayed on the digital readout.

Step 5: Recording Measurements

• Document Measurements:
  • Write down the measurements taken for further analysis.
  • Save data electronically if your readout allows for data export.
• Analyze Results: Compare the measurements with the part specifications to determine compliance.

Conclusion

Operating the Mitutoyo Optical Comparator and QM Data digital readout is essential for accurate machining and manufacturing inspections. By following these steps, you can effectively set up, measure, and analyze your workpieces. For further information or advanced techniques, consider exploring additional resources or tutorials.
