How Precise Cuts Are Generated by Laser Cutting

Laser cutting is one of the fabrication processes that uses a high-powered laser beam to make the necessary cut on various materials and create custom shapes and designs. It is suitable for cutting a wide range of materials, such as wood, plastic, glass, stones, and many more while producing accurate, precise, and intricate parts without the need to use custom-designed tools.

This process includes inert gas cutting or fusion cutting, oxidation cutting, chemical degradation cutting, evaporation cutting, and scribing. Every laser cutting is capable of producing precise and high-quality parts and finishes. Moreover, the process also involves less material contamination, physical damage, and waste than other traditional mechanical cutting processes. The specifications required by a certain laser cutting application, including material type and its properties, type of assist gas used, and secondary finishing, dictate the specific kind of cutting process that is best for use. All of these have to be considered carefully to have a smooth and successful laser cutting process.

Unlike mechanical cutting that uses power-driven equipment and cutting tools, laser cutting utilizes a laser cutter to create cuts, markings, engravings, and other designs on the workpiece. Laser cutting machines come in a wide array of models and types and vary depending on specific applications. However, they mostly have the same setup which includes a laser cutting head, a laser resonator assembly, mirrors, a laser focusing lens, a nozzle, and a pressurized gas assembly.

Moreover, the basic laser cutting process typically includes the stages of beam generation, beam focusing, localized heating and melting, material ejection, and beam movement. Each of these stages is very essential to the entire laser cutting process and once done properly would yield a very precise cut. Finally, laser cutting in Oshawa employs various assist gases that aid the cutting process. Whether an inert or active gas is best to employ is determined by the material being cut and the type of cutting process used.
