PD ISO/TR 10064-1:2019

What is ISO/TR 10064‑1 - Measurement of cylindrical gear tooth flanks about?   

ISO/TR 10064‑1 is the first part in the multi-series of International Standard that is applicable to the code of inspection practice.  

ISO/TR 10064‑1 provides a code of practice dealing with measurements on flanks of individual cylindrical involute gears, i.e with the measurement of pitch, profile, helix, and tangential composite characteristics.  

ISO/TR 10064‑1 describes measuring equipment, provides advice for gear measuring methods and for the analysis of measurement results, and discusses the interpretation of results.  

The main objective of ISO/TR 10064‑1 is to establish standardized methods of gear measurements for improved efficiency of the end-use application. 

Who is ISO/TR 10064‑1 - Measurement of cylindrical gear tooth flanks for?  

ISO/TR 10064‑1 on measurement of cylindrical gear tooth flanks is relevant to: 

• Manufacturers and designers of cylindrical involute gears  
• Manufacturers of precision engineering machines/equipment 
• Mechanical engineers 

Why should you use ISO/TR 10064‑1 - Measurement of cylindrical gear tooth flanks?   

The purpose of ISO/TR 10064‑1 is to provide background information that can assist with understanding the requirements, implementation, and effectiveness of the gear measurements needed to establish the gear classifications. This information can assist those involved in gear design and specification, gear manufacture, and gear measurement processes. ISO/TR 10064‑1 includes background information and guidance on good measurement practice and addresses the interpretation of measurement results to identify common causes of gear manufacturing errors. 

ISO/TR 10064‑1 includes background information and guidance on good measurement practice and addresses the interpretation of measurement results to identify common causes of gear manufacturing errors.  

As a user of ISO/TR 10064‑1, improved knowledge of gear measurement processes can enhance the value of investments in measuring equipment. 

What’s changed since the last update?  

PD ISO/TR 10064‑1:2019 supersedes PD ISO/TR 10064‑1:2017, which has been withdrawn. PD ISO/TR 10064‑1:2019 has been editorially revised, with the following technical changes: 

• Consistently referring to the “reference diameter” and eliminating references to the outdated term “standard pitch diameter” 
• Clarifying what “adjacent pitch deviations” are  
• Clarifying that what is specified is the design profile, and clarifying that what is specified is the design helix 
• Adding chamfers to the list of things in that can be detected on a helix deviation chart 
• Figures 54 and 55 add that the grinding fillet is produced by the finishing tool while the root is created by the pre-finishing tool 
• The factor of 10−3 was added to Formula (43) to account for the specified units
