BS EN ISO 10360-5:2020

What is ISO 10360-5- Coordinate measuring systems (CMS) about? 

ISO 10360-5 specifies acceptance and periodic re-verification tests of CMM performance with contacting probing systems and is only applicable to CMMs using: 

• Any type of contacting probing system 
• Spherical or hemispherical stylus tip(s) 

ISO 10360-5 applies to CMMs supplied with any of the following: 

• Single-stylus probing systems 
• Multi-stylus probing systems with fixed multiple styli attached to a single probe (e.g., “star” stylus) 
• Multiple probing systems such as those with a stylus for each of their probes 
• Systems with articulating probing systems 
• Stylus and probe changing systems 
• Manual (non-driven) and automated CMMs 
• Installations including a scanning probe, capable of being used in a scanning mode 

The term ‘combined CMM and multi-stylus probing system size error’ has been shortened to ‘multi-stylus size error’ for convenience. This applies in similar cases. 

NOTE 1: CMM probing performance tests are specified by the maximum permissible errors (MPEs), due to the impracticality of isolating the performance of the probing system from that of the CMM, even on a small artifact such as a test sphere. 

NOTE 2: ISO 10360-5 is not applicable to non-contacting probing systems, which require different testing procedures. 

Who is ISO 10360-5 - Coordinate measuring systems (CMS) for?  

ISO 10360-5 on acceptance and reverification tests for coordinate measuring systems (CMS) is beneficial for: 

• Manufacturing industries 
• Mechanical engineers 
• Aerospace and space hardware industries 
• Automotive industries 
• Research laboratories 
• Metrologists 

Why should you use ISO 10360-5 - Coordinate measuring systems (CMS)? 

ISO 10360-5 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard. ISO 10360-5 influences chain-link F of the chains of standards on size, distance, form, orientation, location, and run-out. 

The acceptance and reverification tests described in ISO 10360-5 are applicable to coordinate measuring machines (CMMs) that use contacting probes, with or without multiple styli or multiple articulated-probe positions, when measuring using discrete point and/or scanning mode. Experience has shown that the multi-stylus errors calculated using ISO 10360-5 are significant and, at times, represent the dominant errors in the CMM. Owing to the virtually infinite variety of modern CMM probing system configurations, the description of the tests specified by ISO 10360-5 provides a testing protocol for specification. The tests are intended to provide information on the ability of a CMM to measure a feature or features using a contacting probe and, when relevant, using multiple styli, multiple probes, or multiple articulated-probe positions. 

The situations to which they are applicable include: 

• Single-stylus probing systems 
• Multiple styli connected to the CMM probe (e.g., a star) 
• Installations using an articulating probing system (motorized or manual) that can be prequalified 
• Installations using a repeatable probe-changing system 
• Installations using a repeatable stylus-changing system 
• Installations including a scanning probe, capable of being used in a scanning mode 
• Multi-probe installations 

The primary objective of ISO 10360-5 is to determine the practical performance of the complete CMM and probing system. 

Overall, it is believed that the procedures given in ISO 10360-5 will be helpful in identifying CMM system uncertainty components for specific measurement tasks and that the user will be able to reduce errors by removing contributing elements such as long probe extensions and styli, and then by retesting the new configuration settings. 

What’s changed since the last update? 

BS EN ISO 10360-5:2020 supersedes BS EN ISO 103604:2001 and BS EN ISO 103605:2010, which are withdrawn. BS EN ISO 10360-5:2020 cancels and replaces the second edition (ISO 103605:2010), which has been technically revised. BS EN ISO 10360-5:2020 also incorporates with a technical revision the tests contained within ISO 103604:2000 and, as such, it cancels and replaces ISO 103604:2000. 

The main changes to the previous edition are as follows: 

• The adoption of new symbology 
• The addition of an optional ring gauge test  
• Changes to acceptable test parameters e.g., test sphere diameter 
• Changes to Location results evaluation including an “opposing styli” evaluation
