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.
- Fig. 3a shows a turning plate with a straight edge.
- FIG. 3b shows a turning plate with arcuate cutting edge.
- Fig. 3c shows a turning plate with curved, eg elliptical cutting edge.
