Please note this course is over 5 sessions. You will need to attend all sessions to complete the training.

These sessions will include a short introduction on Teams before you access some video presentations individually and try some easy quizzes to test your knowledge. We then get back together on Teams later in the morning to run through the quiz answers and discuss any questions you have and summarise what we have covered. PDFs of the PowerPoint presentations and supporting training information will be sent prior to the event. Also, you will have access to the video sessions for 7 days to run over things again if needed.

Part 1- Introduction to measurement methods and radial composite (double flank) measurement.

The session will:

  • Remind us why we measure gears, failure modes that are influenced by gear geometry

  • Introduce us to the requirements of gears and the involute curve.

  • Introduce single element measurement (helix, profile, pitch and radial runout) and composite measurement (double flank and single flank) methods

  • Look at double flank measurement in more detail including the measurement principles, equipment and ISO 1328-2:2020 tolerance parameters (they are different to earlier version of this document).

  • We have Included plenty of time for questions and discussion.

Introduction to tangential composite (single flank) measurement and tooth thickness measurement.

The session will:

  • Introduce single flank measurement in more detail including the measurement principles, equipment, and ISO 1328-1 tolerance parameters.

  • Discuss the relationship between single flank measurement, Transmission Error (TE) and links to noise and vibration.

  • Introduce fast Fourier Transforms (FFT) without any sums.

  • Discuss the benefits and limitations of tooth thickness measurement methods.

  • We have Included plenty of time for questions and discussion.

Introduction to single element (helix, profile, pitch and runout) measurement

The session will:

  • Introduce single element measurement principles and equipment (CMMs and GMMs)

  • Discuss the importance of gear datum axis definition for measurement.

  • Ensure you are confident with results sheet formats.

  • Look at good measurement practice- how to minimise the risk from common errors.

  • Discuss the benefits and limitations of single element measurement methods.

  • We have Included plenty of time for questions and discussion.

Introduction to single element (helix, profile, pitch and runout) tolerance standards and how to interpret results to a standard

The session will:

  • Introduce ISO 1328-1:2013 cylindrical gear tolerance standard.

  • Review some of the key features that were introduced with the latest revision.

  • Discuss common errors when applying the standard.

  • Work through an example to evaluate the ISO 1328-1 quality grade of a gear.

  • We have Included plenty of time for questions and discussion.

Part 5- Introduction to gear measuring machine calibration

The session will:

  • Introduce common errors in measurement processes

  • Demonstrate how we calibrate a simple hand-held micrometer

  • Review the common sources of error in CNC gear measuring machines and CMMs with gear software

  • Introduce the comparator method and ISO 18653:2003 Gears — Evaluation of instruments for the measurement of individual gears and related information in ISO TR 10064-1:2019

  • Show you how easy it is to apply this standard and how you use the results to

  • We have Included plenty of time for questions and discussion.
