   Ist   dies geschehen, so wird das   Zwischenerzeugnis,   wie aus Fig. 3 ersichtlich, nach der anderen Richtung gegenüber der   Kopiernocke   um   @@ dieser Richtung entsprechenden Betrag des Breitenüberschusses   ihres   ursprünglich nn-   runden Teiles verdreht, derart,   dass   ihre Flanke 6'vor der Flanke b der liopiernocke ebenso um ein Stück vorragt, wie vorhin gemäss Fig. 2 die Flanke a'des Zwischen-   crzcngnisses   vor der Flanke a der   Kopiernocke.   Nun wird der in Fig. 3 schraffierte   Tpil   des Zwischenerzeugnisses abgeschliffen und damit entsteht die in Fig.

   4 dargestellte endgiftige Form der Nocke mit den Flanken   a@,     b",   die symmetrisch zu der   Keihmt r liegen   können, was aber praktisch nicht immer der Fall sein muss. Ist der Breitenüberschuss des Zwischenerzeugnisses an der Maschine nach beiden Richtungen genau ermittelt worden, so ist klar, dass die Nocke gemäss Fig. 4   nunmehr   vollkommen genau die richtige Eröffnung und Schliessung des Ventiles gewährleisten muss. 



   Hat man auf diese Weise eine genaue Steuerungsnocke hergestellt, so kann diese ohncweiters zur Herstellung einer beliebigen Anzahl weiterer Nocken als   Kopiernocke     benutzt werden, 80   dass man also unmittelbar richtige   Nocken t'rhatt.   



   Würde die Befestigung der Nocken auf der Welle in anderer Weise als durch   ein''

 würde selbstverständlich das Abschleifen des Breitenüberschusses auf einer Seite nach gegenseitiger Verdrehung des Zwischenerzeugnisses gegenüber der Kopiernocke um den Gesamtbetrag dieses Breitenüberschusses genügen. Dann müsste selbstverständlich noch die

 are designated. The flank a 'of the intermediate product thus protrudes in front of the flank a of the copying cam by the hatched part and this hatched part of the intermediate product is then sanded off.

   Once this is done, the intermediate product, as can be seen from FIG b the liopiernock also protrudes a bit, as previously according to FIG. 2 the flank a 'of the intermediate crzcngniss in front of the flank a of the copying cam. Now the part of the intermediate product hatched in FIG. 3 is ground off and the result shown in FIG.

   If a precise control cam has been produced in this way, it can also be used as a copying cam to produce any number of further cams, so that the correct cams are used immediately.



   Would the attachment of the cams on the shaft be other than by a ''

 Of course, it would be sufficient to grind off the excess width on one side after the intermediate product has been rotated relative to the copying cam by the total amount of this excess width. Then of course you would have to
