ASME B5.57 – Methods for Performance Evaluation of Computer Numerically Controlled Lathes and Turning Centers

This Standard establishes requirements and methodsfor specifying and testing the performance of CNClathes and turning centers. In addition to clarifying theperformance evaluation of lathes and turning centers,this Standard seeks to facilitate performance comparisonsbetween machines by unifying terminology, generalmachine classification, and the treatment of environmentaleffects. The Standard defines testing methodscapable of yielding adequate performance results forthe majority of turning centers and is not intended toreplace more complete tests. It is not the intent of thisStandard to place limits on, or to enforce 100%-testingof, any individual machine tool in accordance with thisStandard. This shall be the subject of contractual agreementbetween the Supplier and the User.
