Ballbar diagnostic testing is designed to be quick, non-intrusive, and repeatable, providing a clear snapshot of machine tool condition with minimal disruption to normal workshop activity.
Machine type, control, and access requirements are confirmed in advance to ensure the test can be completed efficiently on arrival.
The Ballbar is mounted and a standardised test program is run, typically taking around one hour per machine.
An illustrative animation showing the Ballbar mounting arrangement and broader measurement concepts is shown below.
Results are reviewed using Renishaw software alongside engineering judgement to identify error sources and overall machine condition.
Ballbar data is reviewed off-site to ensure careful interpretation and clear presentation. Reports are issued once the analysis is complete, providing considered findings and practical guidance rather than immediate, on-the-day outputs.
Illustrative example of Ballbar test methods
The animation below illustrates a range of Ballbar measurement techniques, including circular and partial-arc tests, used to assess CNC machine tool performance.
