Educational article: (AP100) Productive Process Pattern: Machine condition monitoring - linear axes (pdf)

When machining a component using a CNC machine tool, the quality of the finished part, for example surface finish and adherence to tolerance, is highly dependent on the positioning and contouring performance of the machine. To maintain machine performance, use a telescoping ballbar to conduct a rapid performance check as part of a preventative maintenance regime, before machine performance is compromised.
