Abstract
The invention relates to a method for machining a toothing, wherein to form a chamfer on a tooth edge formed between an end face of the toothing and a tooth flank belonging to a tooth space of the toothing, material is removed from the tooth edge by cutting, by means of a machining tool equipped with a cutting edge, in a machining operation, wherein the machining tool is toothed and the machining operation is a skiving machining operation at an axis intersection angle between the rotational axes of the machining tool and the toothing, which does not extend beyond the tooth root section of the tooth space.
Claims19
A method for machining a toothing (2), wherein to form a chamfer (5) on a tooth edge formed between an end face (6) of the toothing and a tooth flank belonging to a tooth space (4) of the toothing, material is removed from the tooth edge by cutting, by means of a machining tool (15) equipped with a cutting edge, in a machining operation,
- characterized in that the machining tool is toothed and the machining operation is a skiving machining operation at an axis intersection angle (Σ) between the rotational axes (Z10, Z2) of the machining tool and the toothing, which does not extend beyond the tooth root section of the tooth space,
- wherein first toothing data of a first equivalent toothing (B), whose helix angle is determined by the orientation of the chamfer (5), wherein the transverse section profile thereof matches that of the toothing being machined in the transition (8) from the tooth flank into the tooth edge chamfer being formed, is determined from predetermined chamfer parameters for the chamfer which relate to its size and its orientation to the end face, as well as from toothing parameters of the toothing being machined, relating to its profile, or, profile and helix angle.
A tool arrangement (10) for forming a chamfer (5;
- 9) on the tooth edges formed between an end face of a toothing and its tooth flanks, having a first wheel-like machining tool (15) which is toothed on the front, the axis of rotation (Z10) of which can be pivoted by more than 180° to form the chamfer (5) on one side of the tooth space (4) of the toothing, and having a second wheel-like machining tool (19) which is toothed on the front, with the same axis of rotation (Z10) to form the chamfer (9) on the other side of the tooth space.
