Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for performing the method; See, for example, US-A 3 863 691.
  • the invention is based on the object of improving the tool life in the method according to the preamble of patent claim 1 and of specifying a corresponding device.
  • the result of the method according to the invention is that the workpiece is displaced transversely parallel to the action axis of the tool as it passes through the first working step, so that a tool circumferential action line continuously processes areas that move in the width direction of the tool.
  • the tool axis and the direction of the longitudinal extension of the workpiece can be set perpendicular to one another.
  • the feed movement is carried out at an acute angle ⁇ to the direction of the material joints.
  • These composite materials can, for example, be made of the same material, such as wood, or the different lamellae or layers of the composite material can also consist of different materials. These materials are because of the different material properties, e.g. B. because of the different hardness of the different layers, the problem of groove formation or uneven wear of the tool is particularly serious.
  • the workpieces can be fed automatically across the direction of travel. It is advantageous that the workpieces are moved perpendicular to the longitudinal extension or to the direction of the joint in the direction parallel to the tool axis during the feeding.
  • the feed can take place by means of a cross conveyor or from a magazine.
  • the device according to the invention for performing the method has a longitudinal conveyor for the workpiece, which extends under a lifting and lowering, cutting tool, the axis of the tool being adjustable at an angle of 90 ° - ⁇ to the direction of movement of the longitudinal conveyor. This inclined position ensures that the longitudinal extension and the tool axis of a correspondingly placed workpiece run perpendicular to one another in order to prevent distortion of the desired contour.
  • the device has a machine stand 1.
  • the feed table 2 shown in FIG. 3 is mounted on ball guide bushes 3 so that it can be pushed back and forth in the axial direction.
  • the tool unit 4 is mounted on the side of the machine stand 1.
  • This tool unit 4 carries a height-adjustable cutting tool, which is designed as a copy router 5 in the illustrated embodiment.
  • This copy milling machine 5 is moved up and down in a controlled manner on the tool unit 4 during machining, as is illustrated schematically by the arrow 6.
  • the tool can be a copy grinding unit.
  • FIG. 1 shows, the longitudinal extent and the direction of passage 7 of the workpiece 9 enclose an angle ⁇ .
  • the longitudinal extent and the direction of passage 7 of the workpiece 9 enclose an angle ⁇ .
  • the workpieces 9 are placed on the feed table 2 with their side edges 12 at an acute angle ⁇ with respect to the direction of travel 7.
  • the tool axis 8 runs perpendicular to the side edge 12 of the workpiece 9.
  • contours are generated which have contour lines running parallel to one another or parallel lines of the same profile thickness.
  • a magazine 13 is arranged in front of the tool assembly 4 in the direction of travel 7 of the feed table 2.
  • This magazine 13 receives a stack of workpieces 9.
  • These workpieces 9 are removed from the magazine 13 by a loading device 14 and placed on the feed table 2.
