This diploma thesis deals with the structural design of a notching saw for extruded light alloy profiles. The thesis includes an analysis of the properties of aluminium profiles, an overview of suitable cutting technologies and a review of available industrial solutions. Based on a comparison of design variants, an original machine design is proposed featuring a welded gantry frame, adjustable cutting aggregates, controlled horizontal and vertical feed, a workpiece table with clamping and safety guarding. Selected structural components are verified by design and strength calculations. The result of the thesis is a machine design focused on sufficient rigidity, simple construction, safe operation and applicability in standard manufacturing conditions.
