Step 1: Gather Your Tools

Before starting, ensure you have the double sided GO/NO GO plug gauges, a caliper, and a clean workspace. This preparation helps prevent measurement errors and maintains the integrity of the gauges.

• Get a set of appropriate plug gauges that match the hole specifications.

Step 2: Prepare the Workpiece

Ensure that the hole being measured is clean and free from debris. Any particles or contaminants can affect the fit of the gauge, leading to inaccurate results.

• Use a compressed air blower or cloth to clean the area around the hole.

Step 3: Select the Right Gauge

Carefully choose the gauge based on the required hole size. The GO gauge should fit smoothly into the hole, while the NO GO gauge should not.

• Examine the specifications marked on each gauge for precise measurements.

Step 4: Perform the Measurement with GO Gauge

Insert the GO side of the gauge into the hole. It should go in without significant resistance. If it fits, the hole is on the correct side of tolerance.

• Consider using a gentle twisting motion to ensure the gauge finds the full depth of the hole.

Step 5: Perform the Measurement with NO GO Gauge

Next, take the NO GO side and attempt to insert it into the same hole. It should not fit. If it does, the hole exceeds the allowable size.

• Make sure to apply gentle pressure without forcing the gauge in.

Step 6: Record the Results

Document your findings to keep track of measurements for quality assurance. This step is crucial for maintaining consistent product quality.

• Use a digital or physical logbook to record the measurements, including date and gauge used.

Step 7: Maintain Your Gauges

Regularly clean and calibrate your gauges to ensure they provide accurate measurements over time. This includes storing them properly when not in use.

• Use a soft cloth to clean the gauges after each use.

Common Applications of Double Sided GO/NO GO Plug Gauges

This measurement technique is widely applicable in industries like aerospace, automotive, and manufacturing, where precision is critical. For instance, using these gauges can help in verifying the dimensions of drilled holes in engine components or ensuring the accuracy of pilot holes in aircraft assemblies.

Conclusion

Using double sided GO/NO GO plug gauges is a straightforward process that greatly enhances quality control. By following this step-by-step guide, you can ensure that your measurements are accurate and reliable, contributing to the overall quality of your products.
