What is a small laser-cutting machine?

Defining a laser cutter

The laser cutter is used for cutting and engraving with lasers focused on predetermined designs. This equipment directs the beam with high power through optics and computer numerical control (CNC) systems to cut or engrave materials such as wood, metal, plastic, or fabric. By increasing or decreasing the intensity, velocity, and sharpness of the light source, different levels of intricacy and thickness can be achieved, making it suitable for various purposes in industry as well as at home.

How does a laser cutting machine work?

Laser-cutting machines employ a high-power laser beam that is focused on the surface of a material to either burn through it or engrave it. In this process, the software of these CNC machines and fiber laser machine tools comes into play as it translates computer-generated designs into numerical coordinates required by the machine for execution. These coordinates act as a guide for movement along the x, y, and z axes using a laser. A laser tube generates the actual laser beam, which is then directed to the material using mirrors and lenses. The highly energetic focused laser beam melts, burns, or vaporizes materials upon contact, thus making accurate cuts or etchings possible. All these activities are managed through computer numerical control (CNC) to achieve accuracy and repeatability in design realization.

Applications of laser cutting
