enefits of Ballbar Testing for CNC Machines: Ballbar testing provides a simple, rapid check of a CNC machine tool'spositioning performance to recognised international standards (e.g. ISO, ANSI/ASME etc)allowing users to benchmark and track the performance of their machines and to quickly diagnose problems that may require maintenance and the error sources that produce them.
Regular ballbar testing of machine tools helps to : Ensure accurate parts, first time, from CNC machines Reduce machine down-time, scrap and inspection costs Demonstrate compliance with machine performance and quality management standards Implement fact based predictive maintenance
Overall measures of positioning accuracy (circularity, circular deviation) in accordance with international standards such as ISO 230-4 and ANSI/ASME B5.54 or in Renishaw's own analysis reports. This report uses a unique mathematical analysis to diagnose many additional individual machine errors from the set of linear readings. Data is displayed graphically as well as in numeric format to aid and support diagnosis.
