Summary:A novel thermo-invariant Multi-Feature Bar (MFB) for Machine Tools (MTs) geometric errors' identification has been designed and manufactured. The proposed design of the MFB allows extracting three intrinsic parameters: one linear positioning and two straight-ness errors. The calibration of the MFB was performed on accurate coordinate measuring machines (CMMs) by applying the reversal technique, in order to separate the geometric errors between the MFB and the CMMs. Furthermore , an intercomparison was conducted between four European National Metrology Institutes (LNE, PTB, CMI, UM) to evaluate the reliability of the proposed calibration methodology and the geometric stability of the proposed material standard with respect to a detailed technical procedure. The collected results show sufficient dimensional stability over time.
