als&nbsp;<em>Beweismittel<\/em>, und nicht als Blaupause betrachten.<\/p><p>Beginnen Sie mit einer Erfassung, die Unklarheiten ausschlie\u00dft:<\/p><ul><li><strong>Erfassen Sie den Betriebskontext<\/strong>: zu schneidendes Material (Neuware vs. Mahlgut, gef\u00fcllte Compounds), typischer Durchsatz und das auftretende Verschlei\u00dfbild (schnelles Abstumpfen, Mikroausbr\u00fcche, Hitzespuren, Gratbildung).<\/li>\n\n<li><strong>Fotografieren und kennzeichnen Sie<\/strong>\u00a0das Teil vor der Reinigung (beide Seiten, Montagefl\u00e4chen, eventuelle Markierungen).<\/li>\n\n<li><strong>Messen Sie zuerst die verschlei\u00dffreien Referenzen<\/strong>: Bohrungen, Passfedernuten, Montagefl\u00e4chen, Lochkreise \u2013 Merkmale, die die Position auf der Welle definieren und denen oft mehr vertraut werden kann als der Schneidkante.<\/li><\/ul><p>F\u00fcr die Datenerfassung ist eine Hybridmethode \u00fcblich:<\/p><ul><li>Grundma\u00dfe mit Messschiebern\/Mikrometern<\/li>\n\n<li>Kritische Passungen und Geometrien mittels KMG (Koordinatenmessger\u00e4t) oder 3D-Scanning (insbesondere bei komplexen Messerprofilen)<\/li><\/ul><p>The goal isn\u2019t to collect \u201cas much data as possible.\u201d It\u2019s to collect&nbsp;<em>enough<\/em>&nbsp;data to define datums and control the features that affect fit, runout, and cutting performance\u2014so your&nbsp;<strong>ma\u00dfgeschneiderter Rotationsmesser-Ersatzteile<\/strong>&nbsp;behave predictably when installed.<\/p><h3 class=\"wp-block-heading\" id=\"30763edc-77b9-4202-8e1e-d0d53596ac4a\">Tolerance mapping and CAD<\/h3><p>Once you have measurements, map them into a CAD model around a datum structure:<\/p><ul><li><strong>Primary datum<\/strong>: typically a mounting face or bore that defines axial location<\/li>\n\n<li><strong>Secondary datum<\/strong>: a feature that defines rotation or concentricity (bore, pilot, shaft interface)<\/li>\n\n<li><strong>Tertiary datum<\/strong>: a keyway\/bolt pattern that locks orientation<\/li><\/ul><p>Then, assign tolerances based on how the cutter behaves in the machine:<\/p><ul><li>Fits that control\u00a0<strong>concentricity and runout<\/strong>\u00a0get the tightest attention.<\/li>\n\n<li>Cutting edges and relief angles are controlled to preserve\u00a0<em>function<\/em>\u00a0(cut quality) rather than copying wear.<\/li>\n\n<li>Features that don\u2019t influence assembly or safety can be looser to keep cost sensible.<\/li><\/ul><p>In metrology-focused reverse engineering guidance (for example, Verisurf\u2019s reverse engineering best practices), the recurring theme is the same: define datums early and close the loop between measurement, CAD, and inspection\u2014so you reduce \u201cdo-overs\u201d and supplier interpretation drift over repeat orders.<\/p><p>If you want a formal language for this, the ISO GPS (Geometrical
