Because of

26、this andthe increasing use of this class of measurement equipment, the ASME Standards Committee B89elected to establish a USA industry standard applicable to these machines. At the October 1994meeting, Project Team B89.4.22 was established to develop the Standard.As far as possible, this Standard pa

27、rallels ASME B89.4.1b-2001 for “conventional” coordinatemeasuring machines. An attempt has also been made to make the Standard compatible with ex-isting and emerging international standards.This Standard addresses the performance evaluation of AACMM by supplying definitions andtest procedures. These

28、 procedures should enable users to determine if an AACMM is appropri-ate for their specific requirements. It should also provide accurate comparison of machines fromdifferent suppliers and provide a determination of whether an AACMM meets contractual re-quirements without negotiations after the mach

29、ine has been purchased.The intent of this Standard is to specify the simplest methods that can be used for reasonableperformance evaluation. It is recognized that a more complex evaluation may be appropriate forspecial applications. These methods, however, must be specified in adequate detail in the

30、AACMM specification.This Standard was approved by the American National Standards Institute on August 9, 2004.ivASME B89 STANDARDS COMMITTEEDimensional Metrology(The following is the roster of the Committee at the time of approval of this Standard.)OFFICERSB.

ASME Standards are developed and maintained with the intent to represent the con-sensus of concerned interests. As such

37、, users of this Standard may interact with the Committeeby requesting interpretations, proposing revisions, and attending Committee meetings. Corre-spondence should be addressed to:Secretary, B89 Standards CommitteeThe American Society of Mechanical EngineersThree Park AvenueNew York, NY 10016-5990P

38、roposing Revisions. Revisions are made periodically to the Standard to incorporate changesthat appear necessary or desirable, as demonstrated by the experience gained from the applica-tion of the Standard. Approved revisions will be published periodically.The Committee welcomes proposals for revisio

39、ns to this Standard. Such proposals should beas specific as possible, citing the paragraph number(s), the proposed wording, and a detailed de-scription of the reasons for the proposal, including any pertinent documentation.Interpretations. Upon request, the B89 Committee will render an interpretatio

40、n of any re-quirement of the Standard. Interpretations can only be rendered in response to a written requestsent to the Secretary of the B89 Standards Committee.The request for interpretation should be clear and unambiguous. It is further recommendedthat the inquirer submit his/her request in the fo

41、llowing format:Subject: Cite the applicable paragraph number(s) and provide a concise description.Edition: Cite the applicable edition of the Standard for which the interpretation is be-ing requested.Question: Phrase the question as a request for an interpretation of a specific require-ment suitable

42、 for general understanding and use, not as a request for an ap-proval of a proprietary design or situation.Requests that are not in this format may be rewritten in the appropriate format by the Commit-tee prior to being answered, which may inadvertently change the intent of the original request.ASME

43、 procedures provide for reconsideration of any interpretation when or if additional in-formation that might affect an interpretation is available. Further, persons aggrieved by an in-terpretation may appeal to the cognizant ASME committee or subcommittee. ASME does not “ap-prove,” “certify,” “rate,”

44、 or “endorse” any item, construction, proprietary device, or activity.Attending Committee Meetings. The B89 Standards Committee regularly holds meetings thatare open to the public. Persons wishing to attend any meeting should contact the Secretary of theB89 Standards Committee.viMETHODS FOR PERFORMA

45、NCE EVALUATION OF ARTICULATED ARM COORDINATE MEASURING MACHINESINTRODUCTIONThe primary purpose of this Standard is to clarify theperformance evaluation of articulated arm coordinatemeasuring machines (AACMMs). A secondary purposeis to facilitate performance comparisons between ma-chines. Definitions

46、, environmental requirements, andtest methods are specified. This Standard defines the testmethods capable of yielding adequate results for the ma-jority of articulated arm coordinate measuring machinesand is not intended to replace more complete tests thatmay be required for special applications.1

47、SCOPEThe scope of this Standard pertains to the perform-ance evaluation of articulated arm coordinate measur-ing machines. While any number of rotational joints canbe evaluated, the Standard focuses on the more com-mon configurations commercially available today andis limited to seven joints. The St

48、andard addresses purelymanual machines, so no motorized axes are addressedin the current document. While the application of thisclass of measuring machine continues to grow, at thispoint in time only contact probes are considered and op-tical noncontact probes are specifically excluded.This Standard

49、 establishes requirements and methodsfor specifying and testing the performance of AACMMs.In addition to clarifying the performance evaluation ofAACMMs, this Standard seeks to facilitate performancecomparisons among machines by unifying terminology,general machine classification, the treatment of envi-ronmental effects, and data analysis. This Standard at-tempts to define the simplest testing methods capableof yielding adequate results for most AACMMs and itis not intended to replace more complete tests that maybe suitable for special applications.This Standard provides definitions o
