  • Knife turning device is described in EP 0738569 A1.
  • the rotational position of the knife rotating device 70 is determined by a CNC control that also controls the X and Y positions of the Controls table and knife. It is noteworthy that the Pivoting position of the band knife carrier 20 is not in the X / Y rotary position of the knife, insofar as this is in the Cutting area 30d is located.
  • a hold-down device for the workpiece 3 are attached, for example in the form of Rollers 73. These rollers stabilize the workpiece 3 during of the cutting process.
  • the operation of the form cutting machine is as follows: The one or more workpieces 3 with the workpiece table 1 in moved the cutting area 30d and the band knife 30 on desired Y position moved within the gap 4 to the cutting process at the correct place on the workpiece 3 to be able to start.
  • the band knife 30 is also by the Knife turning device 70 rotated in the cutting direction and through Allow the knife drive motor 35 to start running. Now the workpiece 3 is due to the CNC control precise speed amounts in the X direction and that Move band knife 30 in the Y direction. At the same time the Quotient formed from X and Y and the knife rotating device 70 fed, so that the band knife 30 in the cutting area to the desired cutting direction.
  • any curves or contours can be traversed, such as it is known.
  • the band knife carrier 20 is with its open side 20d moved along the table gap 4 and at the same time with its connecting side 20c along the guides 41 and 42 moved so that the total movement of the band knife carrier 20th as an arched movement with simultaneous Panning can be described. 2 and 3 show the extreme positions of this shifting pivoting movement. Although with this movement of the band knife carrier 20 also the level of the band knife 30 changes, it is significant that the cutting plane of the band knife 30 is not affected by this is because the cutting plane of the band knife only by the Knife turning device 70 is determined in the cutting area 30d.
  • the described embodiment of the Shape cutting machine can be modified. That's the way it is For example, possible to use the drive in the Y direction Perform spindles that are driven by electric motors be over a so-called electrical wave are coupled together to form the carriages 51, 52 and 53 synchronously and to drive equal amounts.
  • the form cutting machine can also be used with so-called Cutting wire work, which is a with Irregular provided endless rope, which cuts equally well in all directions.
  • Cutting wire work which is a with Irregular provided endless rope, which cuts equally well in all directions.
  • the knife rotating device 70 and the grinder 36 is not used.
