Aerospace Laser Cutter - Laser Cutting Is A Much More Efficient Process Than Mechanical Tooling And Cutting Because It Costs Less
Laser cutting is the most accurate process for precise cuts on just about any material.
Aerospace Laser Cutter - Laser cutting is a much more efficient process than mechanical tooling and cutting because it costs less and is much more accurate. The digital control allows for unlimited cutting paths and easy cutting pattern changes that would simply not be practical on a mechanical machine. The laser performs the cut by melting, burning, or vaporizing away the material and leaving a sharp, clean edge. Materials that can be processed by laser cutting include paper and paper board, adhesive tapes, plastics, films, textiles, abrasives, metals, and photovoltaics.
These lasers are created using radio frequency energy and are used for industrial cutting of mild steel, aluminum, stainless steel, titanium, paper, wax, plastics, wood, and fabrics. CO2 lasers have four different variants, fast axial flow, slow axial flow, transverse flow, and slab. Axial flow resonators circulate a mixture of carbon dioxide, helium, and nitrogen with a turbine or blower at different velocities. Transverse flow lasers circulate this mix much slower and slab resonators have static gas fields that do not require pressurization.
Laser beams are produced by stimulating the lasing material, CO2 in some cases, with electrical discharges or lamps within a closed area. Once the material is stimulated, the beam is reflected off a partial mirror until it gathers enough energy to escape as a visible light beam. This light beam is directed to a lens that focuses the beam. The beam is used to make a piercing before cutting. During cutting, the direction of the beam polarization must be rotated to ensure a smooth edge. The two main methods of cutting are vaporization and melt and blow. Vaporization cutting uses the heat of the laser to bring the surface to its boiling point and burn a hole. The hole deepens as the vapor erodes the walls of the hole. Vaporization cutting is ideal for material that does not melt such as wood, carbon, and thermoset plastics. With melt and blow cutting, the material is heated until it melts and the melted part is blown away by a gas jet. This is a common process for cutting metals.
Aerospace Sheet Metal Fabrication - The sheet metal fabricators use different techniques and machinery to shape and bend metals into components, which are supplied to different industries like aircraft, automotive and white goods. The method requires usage of a variety of equipments. From hand held tools like tin snip for cutting thin strips of metal manually to computerized hydraulic press brakes that punch out products related to aerospace industry, the variety is surely impressive.
The demand of hollow and complicated form of sheet metal is increasing every day. Thus the fabrication industry is always prepared to fulfill the increasing demands. There are plenty of ways of fabrication can be done. Cutting or shearing is the first step to transform plain metal to sheet metal. For lighter work manually operated scissors are usually used. The bench shears are used for heavier gauge metals.
Shaping metals is the next step in fabrication. Beading, grooving, folding, crimping and bending are the different techniques used by fabricators. Shaping requires the usage of several machinery, tools and presses. Folding and bending are used to create sections and angles in the metal components. Embossing is also a good technique. It is used to strengthen and decorate the partly finished sheet. Seaming is a technique used to join two prices of sheet metal. This technique is often applied in roofing. And last but not the least is flanging, which is done to add a rim or a lip to facilitate easy, and fast joining.
