example 1
[0123] When shaving, the exact position and the exact shape of the cutting edges of the shaving cutter wheel are especially important in order to produce the desired tooth profile on the workpiece.
[0124] Typically, the tooth profile of the shaving cutter wheel is produced with high precision by the tool manufacturer, however first the exact position of the cutting edge is obtained by grinding the cutting surface. If the shaving wheel is worn, the cutting face is reground and a new cutting edge is formed. The position and shape of the cutting edge is obtained from the position and orientation of the reground cutting face. If the cutting plane is described, for example, by a plane, the orientation can be defined by the normal vector of the cutting plane and the position can be defined by the control point or alternatively by the distance of the plane from the origin of the selected coordinate system. If the cutting surface is described, for example, by a cone, the orientatio...
example 2
[0133] A development of the preceding example provides that, in addition to the position and orientation of the cutting face, the outer diameter of the shaving cutter wheel is additionally measured. In particular, if the shaving cutter wheel is conical, it can be advantageous here to measure the outer diameter and thus determine the enveloping cone at several axial positions of the shaving cutter wheel. Said enveloping cone or enveloping cylinder can be utilized in the case of a shaving cutter wheel of cylindrical shape, in order to define the section of the cutting face by means of a section with the cutting face, said part producing the tooth root region of the workpiece, so as to determine The dedendum profile produced during the shaving process and in particular determines the resulting dedendum circle radius. If the root circle radius produced by means of the machining movement determined in example 1 is not within the desired tolerance, then an attempt can be made to det...
example 3
[0136] A simplified variant of example 1 provides that only the position of the cutting face, that is to say in particular only the regrinding state of the shaving cutter wheel, is determined. The shaving cutter wheels are changed after regrinding and are not known precisely in any case. When regrinding achieves an orientation of the cutting face very well, so that errors occurring on the cutting edge due to deviations from the desired orientation cause deviations in the tooth thickness and / or tooth profile of the workpiece which lie within the desired tolerances Within, the variants described can then be used. It is sufficient here to measure the cutting surface only at one point.
