ma1,2 . x = h1,2 h1 . cos Y1 . cos an, = h2 . cos Y2 . cos an2 = t ne sein. Hieraus ergeben sich a n1 und a n2. Der mit diesen abgeänderten Eingriffswinkeln versehene Fräser erzeugt mit den Zähnen beider Steigungen die gleichen Eingriffsteilungen und damit auch dis gleichen Evolventenprofile am Rad. ma1,2. x = h1,2 h1 . cos Y1 . cos on, = h2 . cos Y2 . cos an2 = t ne . This results in a n1 and a n2. The provided with this modified pressure angles cutter generated with the teeth of the two gradients, the same engaging partitions and thus also dis same involute profiles on the wheel.

Zn Tig. 3 ist die Spanfläche der Zahnreihe 2 des in Tig. 2 in Stirnansicht gezeichneten, der einfacheren Darstellung wegen als gerade genutet angenommenen Fräsers in die Ebene der Spanfläche 1, längs deren der Träser geschnitten ist, hineingeschraubt gestrichelt dargestellt. Man erkennt in diesem Ächaschnitt, daß die wirksaäe Zahndicke des Fräsers mit zunehmendem Abstand vom Zahn in der Fräsermitte nach beiden Enden hin zunimmt. Man erkennt unter Heranziehung der Tig. 1 unschwer, daß an den rechten beziehungsweise linken Flanken eines zu fräsenden Rades jeweils nur die Zähne der einen beziehungs- weise anderen Steigung zum Schnitt kommen. Zn Tig. 3 is the rake face of row 2 of the in Tig. 2 drawn in front view, for the sake of simpler representation, assumed to be straight grooved milling cutter in the plane of the rake face 1, along which the cutter is cut, shown in dashed lines . It can be seen in this Ächaschnitt that the effective tooth thickness of the cutter increases with increasing distance from the tooth in the cutter center towards both ends . You can see the Tig by drawing on it. 1 it is not difficult that on the right and left flanks of a wheel to be milled, only the teeth of one or the other pitch are cut .

Qm dennoch an den Flanken eine genügende Anzahl von Wdllschnitten zu erhalten, wird ein solcher Fräser nicht, wie im Beispiel der ein- facheren-Darstellung wegen angenommen, nur mit acht, sondern mit einer möglichst großen Zahl von Zahnreihen ausgebildet. In order to obtain a sufficient number of incisions on the flanks , such a milling cutter is not designed with eight rows of teeth, as assumed in the example for the sake of simplicity , but with the greatest possible number of rows of teeth.

Wird der iräser beim Fräsen eines Rades axial so eingestellt, daß zum Beispiel ein Zahn auf der Fräsermitte in der mittleren Eingriffsatellung steht (P`ig. 3), dann bestimmt bei zur Radachse parallelen Vorschub dieser und der ihm in der Gangwindung folgende, etwas seit- lich zu ihm versetzte Zahn die Weite der geschnittenen Zahnlücke und damit die Zahndicke der Zähne. Entsprechendes gilt, wenn der Träser axial so eingestellt wird, daß ein Zahn in der Nähe eines If the iräser adjusted during milling of a wheel axially so that, for example, a tooth on the cutter center in the middle is Eingriffsatellung (P`ig. 3), then determined in parallel to the wheel axis feed this and the following it in the Gangwindung, somewhat since - Zahn offset the width of the cut tooth gap and thus the tooth thickness of the teeth. The same applies if the cutter is set axially so that a tooth is in the vicinity of a
