44、ntrolled (CNC) machining centers. The secondary purpose is tofacilitate performance comparisons between machines and to provide for machine evaluationafter refit. Definitions, environmental requirements, and test methods are specified. This Standarddefines the test methods capable of yielding adequa

45、te results for most machines, but is notintended to supplant more complete tests that may be required for particular special applications.This first revision of this Standard provides consistency with the recently published standardfor turning centers (ASME B5.57-1998) with respect to some definitio

46、ns, data analysis, and reportedparameters. To achieve consistency, uncertainty analysis was used to analyze data and reportparameters for many of the procedures, deemed appropriate, within this Standard. Availabilityof improved measurement technology and increasing demand for greater accuracy requir

47、e morerobust procedures for assessing performance of machining centers, as provided within this revisionof the B5.54 standard. This Standard does not address issues of machine safety.This revision was approved by the American National Standards Institute on July 7, 2003 andJanuary 12, 2005.viiiASME
