5.1.2 Axial measuring slide verification
Parallelism of the path of the axial measuring slide with the main spindle axis should be confirmed. A parallel mandrel is required for this evaluation. Alternatively, an accurately manufactured mandrel can be used in conjunction with a self-proving, reversal-method. This verification should apply to the length of the work envelope, or at minimum 80 % of the full travel, see Figures 5 and 6.
5.1.2.1 Centre-mounted mandrel
The mandrel may be mounted between centres. In this case, its orientation concentric with the main spindle axis should be confirmed by two observations. First, its concentricity near the main spindle centre and near the tailstock centre can be confirmed by measuring its radial runout near those centres. Second, its concentricity near the tailstock centre can be confirmed by sweeping the mandrel. If the sweeping set-up recommended for vertical axis instruments is used, the test indicator should be positioned near the tailstock centre. It is recommended that this mounting of the test mandrel be optimized before observation of axial measuring slide parallelism. This may include minimizing runout of the main spindle centre, runout of the tailstock spindle centre, and alignment error of the tailstock slide assembly at this test location.
