What is Laser Cutting Machine
 

Laser cutting machine emits a high powered laser beam to either cleanly cut or etch a specific design on materials such as steel, plastic or wood. It is generally used more for industrial manufacturing applications and the beam will either burn, vaporise or melt away the excess product, leaving a superior finished design or edge.A laser cutting machine has settings known as the computer numerical control (CNC), as well as laser optics, which control and direct the laser beam’s intensity for the desired design effect, or the specific cuts required in a manufacturing or design project. The laser beam is generated by a process whereby electrical discharges or a lamp trigger a lasing material within a confined container causing a chemical reaction, resulting in a high powered beam being released. The beam is then reflected using a mirror in a stream of monochromatic light. From the mirror, the light is then directed by fibre optics or mirrors to the work area, with the narrowest point of the beam cutting or making the design etch on the material.

 

Advantages of Laser Cutting Machine
01/

High precision
The narrowness of the energy beam and the precision with which the material and/or the laser optics can be moved ensures extremely high cutting quality. Laser cutting allows the execution of intricate designs that can be cut at high feed rates, even in difficult or fragile material substrates.

02/

High speed
Few production methods can come close in processing speed to laser cutting. The ability to cut a 40 mm steel sheet using a 12 kW oxygen-assisted laser provides speeds some 10x faster than a bandsaw and 50–100 times faster than wire cutting.

03/

Unlimited 2D complexity
Laser cutting allows intricacy through the nature of the G-code movement control method of positioning and the small size of the applied energy hot spot. Features that are only weakly attached to the main body are cut without any application of force, so the process is essentially limited by material properties, rather than process capabilities.

04/

Variety of materials
Laser cutting is a flexible technology that can be adapted to cut widely different materials efficiently, including: acrylic and other polymers, stainless steel, mild steel, titanium, hastelloy, and tungsten. This versatility is increasing as technology develops. For example, dual frequency lasers can be applied to cut carbon fiber reinforced composites one frequency for the fiber, one for the bonding agent.

How Does Laser Cutting Work
 

Laser cutting machine uses a high-power laser which is directed through optics and computer numerical control (CNC) to direct the beam or material. Typically, the process uses a motion control system to follow a CNC or G-code of the pattern that is to be cut onto the material. The focused laser beam burns, melts, vaporises or is blown away by a jet of gas to leave a high-quality surface finished edge.

 

The laser beam is created by the stimulation of lasing materials through electrical discharges or lamps inside a closed container. The lasing material is amplified by being reflected internally via a partial mirror until its energy is enough for it to escape as a stream of coherent monochromatic light. This light is focused at the work area by mirrors or fibre optics that direct the beam through a lens which intensifies it.

 

At its narrowest point, a laser beam is typically under 0.0125 inches (0.32 mm) in diameter, but kerf widths as small as 0.004 inches (0.10mm) are possible depending on material thickness.

 

Where the laser cutting process needs to start anywhere other than the edge of the material, a piercing process is used, whereby a high power pulsed laser makes a hole in the material, for example taking 5-15 seconds to burn through a 0.5-inch-thick (13 mm) stainless steel sheet.

This process can be broken down into three main techniques - CO2 laser (for cutting, boring, and engraving), and neodymium (Nd) and neodymium yttrium-aluminium-garnet (Nd:YAG), which are identical in style, with Nd being used for high energy, low repetition boring and Nd:YAG used for very high-power boring and engraving.

 

All types of lasers can be used for welding.


CO2 lasers involve the passing of a current through a gas mix (DC-excited) or, more popularly these days, using the newer technique of radio frequency energy (RF-excited). The RF method has external electrodes and thereby avoids problems related to electrode erosion and plating of the electrode material on glassware and optics that can occur with DC, which uses an electrode inside the cavity.

 

Another factor that can affect laser performance is the type of gas flow. Common variants of CO2 laser include fast axial flow, slow axial flow, transverse flow, and slab. Fast axial flow uses a mixture of carbon dioxide, helium and nitrogen circulated at a high velocity by a turbine or blower. Transverse flow lasers use a simple blower to circulate the gas mix at a lower velocity, while slab or diffusion resonators use a static gas field which requires no pressurisation or glassware.

 

Different techniques are also used to cool the laser generator and external optics, depending on the system size and configuration. Waste heat can be transferred directly to the air, but a coolant is commonly used. Water is a frequently used coolant, often circulated through a heat transfer or chiller system.

 

One example of water cooled laser processing is a laser microjet system, which couples a pulsed laser beam with a low-pressure water jet to guide the beam in the same manner as an optical fibre. The water also offers the advantage of removing debris and cooling the material, while other advantages over ‘dry’ laser cutting include high dicing speeds, parallel kerf, and omnidirectional cutting.

 

Fibre lasers are also gaining popularity in the metal cutting industry. This technology uses a solid gain medium rather than a liquid or gas. The laser is amplified in a glass fibre to produce a far smaller spot size than that achieved with CO2 techniques, making it ideal for cutting reflective metals.

Main Components of Laser Cutting Machines

 

Laser cutters work on the concepts of optics like reflection and amplification. The whole working of a laser cutting machine can be broken into two individual systems- the optical system and the mechanical system.


The optical system generates a high-powered laser beam for the cutting process. The mechanical system moves the laser beam around to create the desired shape. Parts of a basic laser cutting system are:

 

● Power Supply: The power source helps generate the light beam.
 

● Laser Resonator: A laser resonator is an assembly of mirrors. It reflects the light beam in the gain medium for amplification.
 

● Cutting Head: Cutting head focuses the laser beam on the desired point of contact.
 

● Mechanical System: The mechanical system involves motors and rails. They move the cutting head around the workpiece.
 

● Motion Control System: The motion control system directs the motors and arms on where to move the laser.
These are only the basic components of a laser cutting system. Modern commercial laser cutters have a lot more parts like cooling stations, dust extractors, and slag discharge systems.

Metals
Laser cutters are becoming the preferred cutting tools in most metalworking shops. Metal laser cutting is used in many industries to make incisions on many different forms of metal. Common variants of metals cut with lasers are sheet metal, rods, pipes, and tubes.

 

Plastics
Plastics are a little tricky to cut with a laser. Unlike sheet metal, some plastics release toxic fumes upon being heated at extreme temperatures. Therefore, knowing what plastics you can cut with laser cutting is important.Some of the plastics that are quite suitable for laser cutting are:Acrylics Delrin Polypropylene Mylar PMMA Polycarbonate POM Polyester Polyethylene.

 

Wood
Laser cutting is one of the best ways to cut wood. Lasers can work on all types of wood without any exceptions. Laser engraving on wood is almost as common as laser cutting procedures. The only thing to consider is the wood thickness. For woods thicker than 20 mm, waterjets can provide better results.

 

Fabrics
Laser cutting works great for fabrics and textiles. Conventional cutting methods often fray the fabric edges. However, laser cutting produces no such unwanted effect. The high heat of the laser creates a clean cut and a sealing effect on the fabric’s fibers.

 

Paper Products
Laser-cut paper is often used for cardboard boxes, packaging products, dioramas, and decorative applications like wedding invitations and bunting. Additionally, the consistency produced by laser-cutting paper is second to none.

 

Foam
Laser cutters make smooth cuts on foam without any rough edges. However, ensuring that the foam you cut does not release any toxic fumes on heating is important. Some safer foams to cut with a laser are polyurethane, polyethylene, and polyester. Some foams, like Expanded Polystyrene foam, are flammable and don’t release damaging fumes. These require extra caution while cutting with a laser.

 

Glass
Glass is a very brittle material and uneven force or unbalanced heat can easily crack it. Therefore, laser cutters use fracture-controlled cutting for glass. Etching on glass with a laser is also very common. It is particularly used for decorative items like trophies and panels.
