| 88 | Method of machining a workpiece, and gear-cutting machine operable to perform the method | US14408406 | 2013-06-17 | US09937574B2 | 2018-04-10 | Gerhard Krebser |
| The invention concerns a method of machining a workpiece, wherein an end-facing tooth edge of a gear profile of the workpiece that was generated by a chip-removing machining process is reworked at a first location into a chamfered edge by way of a plastic forming operation. The material which in the plastic forming operation was displaced towards the end surface of the gear profile is pushed outward as a material protrusion in the end surface of the tooth, while the material displaced towards the flank of the tooth is pushed outward as a material protrusion on the flank side of the chamfer, and the resulting material protrusions in the end surface and on the flank side are removed. The workpiece, while still carrying the material protrusion on the end surface of the gear profile, is transferred to a second location where the protrusion on the flank side of the chamfer is removed. | ||||||

| 92 | Method for producing toothed sections on workpieces | US14110186 | 2012-04-05 | US09346112B2 | 2016-05-24 | Holger Fleischer; Mario Wiesel |
| In a method for producing toothed sections on workpieces, a toothed section is firstly produced by means of a first tool in the region of a first end face of a workpiece to be toothed. The produced toothed section is reworked on the peripheral face by means of at least one second tool in the region of the first end face, while the toothed section is further produced. If the toothed section is also produced in the region of the second end face by means of the first tool, the reworking in the region of the first end face is already completed, so the toothed section can also be reworked in the region of the second end face. Short cycle times are thereby achieved with a low machine-related outlay. | ||||||
| 93 | Semi-completing skiving method and device having corresponding skiving tool for executing a semi-completing skiving method | US13617277 | 2012-09-14 | US09199323B2 | 2015-12-01 | Hartmut Marx; Olaf Vogel |
