Abstract

Ein dreidimensionaler Nocken wird durch die periphere Fläche (5) eines Rotationskörpers (4), der den Nocken auf seiner gesamten Länge (11) berührt und dessen Rotationsachse (6) die Rotationsachse (3) des Nockens bei der Erzeugung des Grundkreiszylinderabschnitts (2) des Nockens kreuzt, hergestellt. Dabei werden der Erhebungsabschnitt des Nockens (1) und die an diesen angrenzenden Bereiche des Grundkreiszylinderabschnitts (2) nur einmal überfahren. Zur Erzeugung des Erhebungsabschnitts führt der Rotationskörper (4) Bewegungen aus, die eine Drehung um eine Achse (12) beinhalten. DOLLAR A Von einem nach diesem Verfahren hergestellten dreidimensionalen Nocken kann ein Nockenfolger bei Verschiebung des Nockens längs seiner Rotationsachse unterschiedliche Erhebungskurven abgreifen.
