Abstract
A method (100) of producing toothed blades from a strip material (200, 250) is disclosed. The method (100) comprises: cutting the strip material using combined laser cutting (102a) and mechanical machining (104a) or using waterjet cutting (102b) to form a plurality of teeth in an edge of the strip material (200, 250), wherein the cutting is controlled to cut each of the teeth using a flexible programmable geometry. A toothed blade production line (300, 400) arranged to produce toothed blades from a strip material using the method is also disclosed.
