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

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

This is part 1 of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to measure and interpret gear measurement results.  No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation and Introduction to Gear Geometry online courses.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry and want to understand why you need to invest in precise gear measuring equipment.  We will dispel the myth that measuring machines only produce scrap.

The session 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.

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.

Key skills and knowledge:

By the end of the session you will understand why we measure gears, the difference between the composite and single element measurement strategies and be familiar with double measurement principles, equipment and related ISO standards.  Designing, manufacturing and inspection processes make much more sense when you understand what measurements will and won’t do for you.  You will be ready to develop your knowledge further in the next gear measurement sessions from the BGA.

Cylindrical gear geometry measurement Part 2- Introduction to tangential composite (single flank) measurement and tooth thickness measurement.

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to measure and interpret gear measurement results.  It follows the previous introduction covered in part 1 of this session.  No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation and Introduction to Gear Geometry online courses.

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.

Key skills and knowledge:

By the end of the session you will understand with single flank measurement principles, equipment and related ISO standard, and be familiar with tooth thickness measurement methods and good measurement practice.  Designing, manufacturing and inspection processes make much more sense when you understand what measurements will and won’t do for you.  You will be ready to develop your knowledge further in the next gear measurement sessions from the BGA.

Cylindrical gear geometry measurement Part 3- Introduction to single element (helix, profile, pitch and runout) measurement

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to measure and interpret gear measurement results.  It follows the previous session looking at single flank and tooth thickness measurement covered in part 2.  No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation and Introduction to Gear Geometry online courses.

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.

Key skills and knowledge:

By the end of the session you will understand single element measurement principles and how we measure those tricky involute profiles, appreciate the different equipment options, and be introduced to good measurement practice.  Designing, manufacturing and inspection processes make much more sense when you understand what measurements will and won’t do for you.  You will be ready to develop your knowledge further in the next gear measurement session from the BGA.

Cylindrical gear geometry measurement Part 4- Introduction to single element (helix, profile, pitch and runout) tolerance standards and how to interpret results to a standard

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to measure and interpret gear measurement results.  It follows the previous session looking at single element measurement methods covered in part 3.  No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation and Introduction to Gear Geometry online courses.

Cylindrical gear geometry measurement Part 5- Introduction to gear measuring machine calibration

This is part of a series of short on-line training sessions that will introduce delegates to the key skills and knowledge needed to calibrate gear measuring machines. It follows the previous session looking at interpreting measurement results to a standard. You can only properly interpret measurement results if you know how accurate your measuring equipment is. Every day we are accepting gears which are outside tolerance and rejecting gears with are inside tolerance because of errors in the measurement process. No prior gear knowledge is required but those who are new to gear technology would benefit from participating in the BGA Gear Foundation, Introduction to Gear Geometry and earlier measurement online courses in this series.

It is applicable to gear designers, manufacturing staff, machine operators, inspectors and those who are new to the gear industry and want to understand why you need to invest in precise gear measuring equipment.

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.

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.

Key skills and knowledge:

By the end of the session, you will appreciate that all measurement results are wrong, but some are useful. You will be able to assess the suitability of equipment for measuring your product gears and quantify the benefits from investing in new equipment. You will be ready to develop your knowledge further in the next gear measurement session from the BGA looking at interpreting the cause of manufacturing errors, we are currently planning.
