Definitions

  • the invention relates to a hogging tool for working edges of panels, said hogging tool having a body with a circular circumference and an axially oriented surface, and where the hogging tool is provided with a set of chip cutting edges extending along the circumference of the hogging tool and intended for pre-working the edge of the wooden panel, and a set of chip cutting edge extending along the axially oriented surface and intended for finishing working the edge of the wooden panel.
  • the invention also relates to a method utilising the hogging tool and to an apparatus for utilising the hogging tool.
  • edges of panels are used when an edging foil or other lining is to be attached to the edge of the panel. It is necessary that the edge is plane so that a secure attachment of the lining is possible. If the edge is not plane, or if the roughness of the edge is too coarse, the lining may detach.
  • a hogging tool may be used being provided with a plurality of cutting edges.
  • the cutting edges are extending both along a circumference of the hogging tool and along an axially oriented surface of the hogging tool.
  • the cutting edges running along the circumference are intended for pre-working the edge of the panel by engaging a top side of the panel and working a certain width off the panel edge.
  • the cutting edges running along the axially oriented surface are intended for finishing working the panel edge by engaging the edge side of the panel and providing the surface of the edge.
  • US 6,039,096 discloses a tool for working the edges of a panel.
  • the hogging tool has a front surface, a working plane and a circumferential surface, and defines an axis of rotation, comprising at least one row of cutter teeth extending about the circumferential surface, said cutter teeth serving for pre-working, and a row of teeth for finishing working, the teeth being situated on the front surface, wherein the teeth of both rows have radially cutting edges and axially cutting minor cutting edges, said minor cutting edges defining rotary surfaces which make a transition into each other such that the combine rotary surface forms a setting angle which is reduced according to one of: continuously or in sections, from being oriented radially outward to radially inward with respect to the working plane, the working plane extending perpendicularly to the axis of rotation.
  • the hogging tool of US 6,039,096 exhibits reduced noise emission.
  • One row of cutter teeth extends about the circumferential surface, said cutter teeth serving for pre-milling, and another row of teeth for finishing milling extends on the front surface.
  • the teeth of both rows have radially cutting edges and axially cutting minor cutting edges.
  • the reduction in noise emission is brought about by reducing the vibrations produced in the tool and work-piece and by proportioning the cut, machining being carried out in two stages.
  • the greatest part of the chip volume is removed under favourable noise-emission conditions using a special cutting geometry.
  • the tool and work-piece vibrations are reduced by a clearly reduced rise in the shear force pulse using a special cutting tooth geometry.
  • the chip volume removed under these conditions is only small, and good quality machining can thus be obtained. Problems of cutting marks along the edge of the working panel occurring are not addressed.
  • the row of cutter teeth intended for finishing working extends along only a part of the axial surface of the tool.
  • the row of cutter teeth intended for finishing working extends also along the circumference of the tool.
  • the pre-working row of cutter teeth defining the finished surface of the working plane.
  • Cutting marks along the worked surface of the work-piece will occur, when The row of cutter teeth intended for finishing working also extends along the circumference of the tool.
  • DE 101 07 881 discloses a tool which has several circumferentially spaced pre-cutting blades arranged around the circumference of the tool body and with radially acting edges whilst secondary cutting blades have axially acting edges.
  • Each cutting blade has a dedicated chipping space whose volume are different from each other so that the larger spaces are allotted to the cutting blades having the larger chipping surface.
  • the chipping spaces open alternately to every second axial side. Accordingly, there are one set of radially acting cutting edges and one set of axially acting cutting edges. Problems of cutting marks along the edge of the working panel occurring are not addressed.
  • the axially acting cutting edges are intended for "cleaning up" the surface of the work-piece and for “smoothing out” any broken edges of the work-piece, after the work-piece has been worked by the radially acting cutting edges.
  • the axial surface of the tool is only defined by one set of cutting edges. The results of only having one set of axially acting cutting edges is that the surface of the work-piece is in fact only being pre-worked. When the work-plece is only being pre-worked, cutting marks will occur along the worked surface of the work-piece.

    - wobei der mit der Drehachse (A) gebildete Winkel (θ) einen Wert von mindestens 0 Grad, möglicherweise zwischen plus 5 und plus 30 Grad, vorzugsweise zwischen plus 10 Grad und plus 20 Grad aufweist und wobei der Winkel (θ), der einen positiven Wert hat, von einem Radius R des Zerspanungswerkzeugs nach vorne im Verhältnis zur vorgesehenen Drehrichtung des Zerspanungswerkzeugs gemessen wird.
  9. Verfahren zur Herstellung von Holzplatten mit einer zu fräsenden Kante, wobei das Verfahren Folgendes umfasst
    - Bereitstellen eines rotierenden Zerspanungswerkzeugs nach einem der Ansprüche 1-8 mit einem für die Vorbearbeitung vorgesehenen Satz erster Schneidkanten am Umfang, einem für die Vorbearbeitung vorgesehenen Satz axialer erster Schneidkanten und einem für die Fertigbearbeitung vorgesehenen Satz zweiter Schneidkanten,
    - Drehen des Zerspanungswerkzeugs um eine Drehachse, wobei sich der Satz erster Schneidkanten und der Satz zweiter Schneidkanten entlang eines Umfangs des Zerspanungswerkzeugs erstrecken, und
    - wobei der Satz erster Schneidkanten am Umfang radial nach außen im Verhältnis zur Drehachse ausgerichtet ist, wobei der Satz axialer erster Schneidkanten axial im Verhältnis zur Drehachse ausgerichtet ist und wobei der Satz zweiter Schneidkanten axial im Verhältnis zur Drehachse ausgerichtet ist,
    - Drehen des Zerspanungswerkzeugs mit einer bestimmten Drehgeschwindigkeit, wobei die Drehgeschwindigkeit auf der Grundlage einer radialen Ausdehnung der mindestens einen zweiten Schneidkante entlang der axialen Richtung gewählt ist,
    - Bereitstellen einer Verschiebung einer Platte in Abhängigkeit von einer Richtung senkrecht zur Drehachse des Zerspanungswerkzeugs, sodass die mindestens erste Schneidkante in eine obere Fläche der Platte eingreift und sodass die mindestens zweite Schneidkante in eine Kante der Platte eingreift,
    - wobei die Verschiebung der Platte im Verhältnis zur Drehachse mit einer Verschiebungsgeschwindigkeit ausgeführt wird, die auf der Grundlage der Drehgeschwindigkeit des Zerspanungswerkzeugs gewählt ist.
  10. Vorrichtung zur Herstellung von Holzplatten mit einer zu fräsenden Kante, wobei die Vorrichtung Folgendes Folgendes umfasst
    - ein rotierendes Zerspanungswerkzeug nach einem der Ansprüche 1-8 mit einem für die Vorbearbeitung vorgesehenen Satz erster Schneidkanten am Umfang, einem für die Vorbearbeitung vorgesehenen Satz axialer erster Schneidkanten und einem für die Fertigbearbeitung vorgesehenen Satz zweiter Schneidkanten,
    - wobei sich der Satz erster Schneidkanten und der Satz zweiter Schneidkanten entlang eines Umfangs des Zerspanungswerkzeugs erstrecken, das auf einer Drehachse der Vorrichtung montiert ist, und
    - wobei der Satz erster Schneidkanten am Umfang radial nach außen im Verhältnis zur Drehachse ausgerichtet ist, wobei der Satz axialer erster Schneidkanten axial im Verhältnis zur Drehachse ausgerichtet ist und wobei der Satz zweiter Schneidkanten axial im Verhältnis zur Drehachse ausgerichtet ist,
    - einen Träger für eine Platte,
    - Mittel zum Steuern einer Drehgeschwindigkeit der Drehachse und Mittel zum Steuern einer Verschiebung des Trägers für eine Platte vorbei an dem auf der Drehachse montierten Zerspanungswerkzeug,
    - Mittel zum Steuern der Geschwindigkeit der Verschiebung des Trägers für die Platte vorbei an dem auf der Drehachse montierten Zerspanungswerkzeug auf der Grundlage der Drehgeschwindigkeit der Drehachse.
