Description
Rechenschieber. Anstatt die Spantiefe durch einen besonderen, drehbaren, im Arm q. verschiebbaren Schieber g festzustellen, kann man in einfacher Weise auch die gesuchten Geschwindigkeiten und Vorschübe für eine bestimmte Spantiefe durch das am Arm q. verschiebbare Lineal 5 ermitteln, wenn der Arm ¢ mit Teilungen versehen wird, auf die die obere oder untere Kante des Lineals 5 eingestellt wird.Slide rule. Instead of the cutting depth by a special, rotatable, in the arm q. determine sliding slide g, you can also in a simple manner the searched speeds and feeds for a certain depth of cut that on the arm q. Determine the movable ruler 5 if the arm ¢ is provided with divisions to which the upper or lower edge of the ruler 5 is set.
Die Zeichnung veranschaulicht diese vereinfachte Ausführungsform- des Rechenschiebers in Ansicht. Wird das Lineal 5, wie aus der Zeichnung ersichtlich, mit seiner unteren Kante auf die Marke der Spantiefenskala des Armes 4 eingestellt, so zeigt der Stein 7 auf der Umdrehungs- oder Vorschubskala die richtigen Umdrehungen und den richtigen Vorschub. Um die ganze Länge des Lineals 5 auszunutzen, kann ein Teil der Skala auch auf den oberen Teil des Armes 4. angebracht werden, so daß dann die obere Kante des Lineals 5 auf diesem Teil der Spantiefenskala einzustellen ist.The drawing illustrates this simplified Embodiment- of the slide rule in view. If the ruler 5, as can be seen in the drawing, with its lower edge set to the mark of the depth of cut scale of arm 4, so the stone 7 shows the correct revolutions on the revolution or feed scale and the right feed. In order to use the entire length of the ruler 5, a Part of the scale can also be attached to the upper part of the arm 4. so that then the upper edge of the ruler 5 is to be set on this part of the depth of cut scale.
