Abstract (en)
[origin: US4443977A] In order to machine skew surfaces, adjacent cylindrical shaping rollers in adjacent relation are each freely mounted for rotation on roller support frames which are each capable of relative backward or forward longitudinal displacement under the action of a numerical control system. An abrasive belt which is applied against a portion of the periphery of the set of shaping rollers assumes during this portion of travel a configuration corresponding to the instantaneous envelope curve of the transverse cross-sections of the rollers and thus constitutes a tool which provides a variable profile for abrasive machining operations.
