Keywords: generalized helical surfaces; surfaces of revolution; focal surfaces
Summary/Abstract: Generalized helical surfaces are obtained from the helical surfaces by replacing straight line, which rotates with arbitrary plane curve. Surfaces of revolution belong to the generalized helical surfaces. Surfaces of revolution with one axis are discussed and the their focal surfaces are presented. Their properties and applications are also studied.
