Definitions

  • the invention relates to a method and a device for machining workpieces with both non-circular and rotationally symmetrical inner and outer contours.
  • the turning of soft or hardened workpieces with certain cutting edge is state of the art.
  • a thread-like structure in the form of rotational depths or workpiece elevations inevitably arises on the workpiece surface as a result of the feed of the tool along the rotating workpiece.
  • DE 102004 026 675 B3 discloses a method for machining rotationally symmetrical surfaces of a workpiece.
  • the tool cutting edge is moved around the tool rotation axis in the form of a helix coaxial with the tool rotation axis with an arcuate feed motion so that the point of action travels between the cutting edge and the workpiece along the cutting edge.
  • the production and maintenance of helical cutting edges, which extend coaxially to the tool rotation axis is comparatively complicated and expensive.
  • this method is not suitable for machining non-circular workpiece contours.
  • the invention is based on the object, a method and an apparatus for processing both non-circular and rotationally symmetrical inner and
  • the core idea of the invention is to use a tool with a flat, oblique to the workpiece rotation axis cutting edge, which is moved with a circular arc-shaped feed movement about a pivot axis, to achieve swirl-free workpiece surfaces.
  • the contour deviations of the workpiece due to the planar cutting edge shape are compensated by a relative movement between the workpiece and the tool.
  • non-circular workpiece contours, such as cam shapes can be edited.
  • the axes of rotation of the tool turret and the workpiece are arranged in parallel.
  • the circular arc-shaped feed movement of the tool cutting edge can be carried out particularly advantageously by a pivoting movement of the tool turret.
  • Fig. 1 shows a machine tool with two tool turrets
  • Fig. 2 shows the tool turret seen from above
  • Fig. 3 shows inserts with different cutting shapes
  • Fig. 1 shows a machine tool 1, in which not essential to the invention details of the workpiece feed, the drive, the controller and the housing are not shown.
  • the machine tool 1 described is particularly suitable for machining wave-shaped workpieces 7. These are clamped in the workpiece holding device consisting of the motor spindle 8 and the tailstock 9 and set in rotation.
  • the two tool turrets 10 and 11 are guided on the machine frame 2 in two mutually orthogonal directions (X and Z axis) movable.
  • vertical guides 3 for the vertical slides 4 are provided on the machine frame 2.
  • the motors 6 with the ball screws 14 serve as a drive.
  • the vertical slides 4 carry guides 12 for the horizontal slides 5.
  • Fig. 2 shows the tool turrets 10, 11 in the view from above.
  • the tool 15 is brought with the cutting edge 17 with a circular arc-shaped feed movement with the workpiece in engagement.
  • the contour deviations of the workpiece caused by the cutting edge shape are compensated by a feed movement of the horizontal carriage 5 along the guides 12.
  • the flat cutting edge 17 is designed as a turning plate.
  • a support bearing 16 is provided instead of a tool.

Abstract

L'invention concerne un procédé et un dispositif permettant d'usiner des pièces présentant des contours intérieurs et extérieurs aussi bien en faux-rond qu'à symétrie de rotation sur une pièce rotative. Au moins un outil à tranchant droit vient en contact avec la pièce; le tranchant est incliné à un angle α par rapport à l'axe de rotation de la pièce; le tranchant est déplacé autour d'un axe de pivotement avec un mouvement d'avance en arc de cercle; pendant le déplacement en avant, le point d'action entre la pièce et l'outil migre le long du tranchant et un mouvement d'avance produit les contours intérieurs et extérieurs en faux-rond de la pièce et/ou compense les écarts de contours inhérents à la forme de la coupe.
