Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.
In textile manufacturing, a laser cutting bridge system is an industrial machine for cutting and engraving textile materials (i.e. fabrics). It is formed by a galvanometric laser head and carbon-dioxide laser (CO 2 laser) source that runs along an horizontal beam (the bridge) supported by two lateral columns and sometimes by central columns.
Lathe-A CNC lathe removes material by rotating the work-piece while a stationary cutting tool is brought into contact with the material. Laser cutting-A Laser cutter is a CNC tool that uses a focused laser beam to cut and engrave sheet material. Cutting can be done on plastics, woods and on higher power machines, metal.
Most types of laser are an inherently pure source of light; they emit near-monochromatic light with a very well defined range of wavelengths.By careful design of the laser components, the purity of the laser light (measured as the "linewidth") can be improved more than the purity of any other light source.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).

The laser also has the ability to melt and seal the edges of fabric with the heat of the laser. This helps against fabric fraying during the creation process. [14] Additionally, using a laser for cutwork enables the embroiderer or creator to achieve unique designs such as an 'etched look' by changing the depth of the laser cut into the fabric.
