Performance Calibration of Articulated Arm Coordinate Measuring Machine

This paper presents the process to carry out performance calibration of Articulated Arm Coordinate Measuring Machines according to ASME B89.4.22 Standard. The growing use of this class of measurement equipment has been accompanied by an absence of authorized laboratories to provide calibration certificates for AACMM's performance. Due to ASME B89.4.22 and VDI 2617-9 are nowadays the unique standards in the field of AACMM verification, IK4 Tekniker has compared both of them in order to develop internal test procedures to yield reliable performance calibration results.IK4 Tekniker has achieved ENAC accreditation in the field of AACMM calibration. Internal test procedures and uncertainty evaluation analysis have been developed, as well as ENAC certificated reference test equipments have been acquired.
