Accuracy when using laser cutting technology for production

Precise laser cutting is a relatively new industrial machine manufacturing process and has quickly become popular in a variety of industries. The removal of materials using laser technology requires the use of a computer to guide the laser, thereby effectively melting, evaporating, or blowing away the desired portion of the material. Precise laser cutting is used to form a variety of basic materials, including metals, plastics, and paper goods.

Precision Laser cutting process
Precise laser cutting is done in the same way as a traditional milling machine. Both techniques allow for cutting on the X, Y, and Z direction axes applied to the cutting mechanism. Meanwhile, a milling machine uses a drill to make cuts, a laser cutting machine uses a high power laser.

Laser cutting is the easiest for the product, allowing cutting to begin at the edge of the material. If the original cut of the product can not be started at the edge, then the piercing cut is necessary to create a flaw originated in the material. The majority of precision laser cutters have both penetrating and continuous wave-cutting capabilities. Pierce Pierce usually adds a few seconds of part production time and should be avoided if possible.

Laser cutting offers many advantages over traditional metal cutting techniques because laser cutting produces no physical contact with the material being cut. As a result, laser cutting provides improved accuracy and can cut complex shapes. Other benefits include homogeneity over a wide range of parts, reduced partial deformation, and the ability to quickly create design changes. In addition, the risk of injury is minimized.

Laser cutting equipment
Laser cutting machines have two types: CO2 gas and solid state Nd: YAG. The interesting CO2 laser of the atoms is in a mixture of CO2 that resides in the laser chamber. When excited, the electrons in the molecule expel some of their energy in the form of light energy. The result is a high-temperature laser beam that melts, evaporates, or burns contact points created with the facility.

The carbon dioxide laser cutting machine produces continuous waves at higher powers than the Nd: YAG laser. They are also quite efficient continuous output power for industrial CO2 laser cutters ranging from a few milliwatts (mW) and a few hundred kW (kW). A radio frequency current or can be used to stir the CO2 mixture. RF resonances are less susceptible to electrode erosion and are therefore more common.

Nd: YAG laser uses a solid crystal constructed from neodymium-doped yttrium aluminum garnet. In this type of laser cutting device, light is emitted by optical crystal pumps using a flash lamp or laser diode. The traditional wavelengths of Nd: YAG lasers are 1064 nm, but other wavelengths may occur, they are often used for cutting or welding steel. Nd submersible: YAG laser is ideal for engraving on metal and under glass surface markings. Nd: YAG precision laser cutting is also widely used in automotive industry for cutting and welding components.

Cutting profile of Precision Laser
Laser beams can move through the facilities in a variety of ways to achieve maximum cutting results. In production applications, available laser cutter configurations include the following three options:

Moving laser cutting material: The piece work is physically moving around the laser beam to create the desired cut. A stationary cutting head allows for less uniform optical and optical spacing.

Laser beam cutting: The work piece stays still while the laser head moves to create the desired cut. Most optical lasers can travel in all directions vertically and horizontally. This type offers the fastest results and is ideal for applications requiring cutting materials of varying thicknesses and sizes.

Laser cutting: Both piece work and laser head are transferred to create the desired cut. Traditionally, the object moves along the X axis while the cutting head moves along the Y axis. This allows for easier beam delivery and minimizes power loss in some applications.
