A reference object based method to determine the parametric error components of coordinate measuring machines and machine tools

Geometric error measurement and compensation of machines—An update

“…A conventional laser interferometer has a long-working range, but the variation of the Fig. 12. (A) 2D artifact with calibrated co-ordinates of holes manufactured from Zerodur [138]. (B) 1D carbon fiber artefact with calibrated sphere co-ordinates [140].…”

Kinematic Calibration of Articulated Arm Coordinate Measuring Machines and Robot Arms Using Passive and Active Self-Centering Probes and Multipose Optimization Algorithm Based in Point and Length Constrains

“…While for a CMM an X, Y, Z point clearly defines a position of the three machine axes, for an AACMM the possible positions of its elements to achieve a fixed point defined in the measurement volume are practically www.intechopen.com Kinematic calibration of articulated arm coordinate measuring machines and robot arms using passive and active self-centering probes and multipose optimization algorithm based in point and length constrains 259 infinite, according with its inverse kinematics. Moreover, for CMMs, besides the general evaluation methods, it is possible to carry out evaluation tests in order to extract the positioning errors to finally implement correction models (Trapet & Wäldele, 1991). The CMM evaluation tests achieve a high level of maintenance of the physical-mathematical relations between the error model parameters and the error physically committed by the machine.…”

Traceability on Machine Tool Metrology: A Review

“…It is based on a numerical simulation of the measuring process allowed for uncertainty influences, where important influence quantities are taken into account [2]. For that purpose, CMM suppliers, research companies and national metrology institutes (NMI) as PTB and NPL created an uncertainty evaluation software (UES) which is based on Monte-Carlo simulation of the error behaviour of a real CMM [40,41]. In recent years, Virtual gear measuring instrument (VCMM-Gear) and Virtual laser tracker (VLT) have been developed but they have not been integrated into a manufacturer software yet [42].…”
