OBRABOTKAMETALLOV Vol. 23 No. 3 2021 MATERIAL SCIENCE EQUIPMENT. INSTRUMENTS 6 4 4 The calculated nominal dimensions are added into the CAD model (Fig. 9), and a new geometry of surfaces 1–4 is created. After the changes weremade, themaster models were re-grown on the original mode. Master models were grown vertically. Supports were located on the non-working part of the electrode. Repeated measurements of fl atness deviations of all surfaces of the master models were performed. Table 6 shows the repeated measurements of the TE models.
