Abstract
The invention relates to a process for working a workpiece held between a counterholder and a guide by a clamping force by forming a profile, e.g. precision toothing, in a surface of the workpiece by means of a forming element, the forming element being guided toward the surface of the workpiece at an acute angle (w) to the clamping force or with a rotary/thrust movement.
Claims8
A method for forming a profile on a surface of a workpiece comprising:
- clamping a workpiece having a work surface and a thickness between a counterholder and a guide which contacts a portion of the work surface with a clamping force, said guide having an aperture;
- providing a forming element having a surface substantially parallel to the work surface, the surface having a pattern for forming a profile on the work surface of the workpiece;
- guiding the forming element through the aperture toward the clamped work surface for contacting the work surface;
- and
- providing relative rotational movement between the forming element and the work surface while in contact with the work surface for forming a profile on the work surface of the workpiece having a depth less than the thickness of the workpiece.

An apparatus for forming a profile on a surface of a workpiece comprising:
- clamping means for clamping a workpiece having a work surface and a thickness between a counterholder and a guide which contacts a portion of the work surface with a clamping force, said guide having an aperture;
- profile forming means having a surface substantially parallel to the work surface, the surface having a pattern for forming a profile on the work surface of the workpiece, wherein the profile has a height which is less than the thickness of the workpiece;
- means for guiding the forming element through the aperture toward the clamped work surface for contacting the work surface;
- and
- means for providing relative rotational movement between the forming element and the work surface while in contact with the work surface for forming a profile on the work surface of the workpiece the depth of which is less than the thickness of the workpiece.
