METHOD FOR MILLING FISHBONE-TYPE NOTCHES |
摘要 |
The invention relates to a method for milling fishbone-type notches (3) which are arranged on the perimeter of a turbine shaft (2) and which are used to receive blade footings. A step-tapered preform (15) of the cross-section (3) of the notch is pre-milled in preferably three machining steps. On the basis of this preform (15), at least the substantial part of the fishbone-type cross-section form which is characterised by undercuts in the step flanks is milled in one tool passage by means of a profile milling cutter (21). |
