What Is Laser Cutting

Laser cutting is a manufacturing process that uses a laser beam to slice through or engrave shapes on a work piece. The technology is commonplace in industrial fabrication, where it’s typically used to cut various types of sheet metal such as steel, stainless steel, aluminium and copper.

Advantages of Laser Cutting

01/

All-In-One Setup
Unlike many manufacturing machines, laser cutters typically do not require you to switch out different tools for whatever cut you want. The nice thing about laser cutting machines is that they can work within the same setup while offering various cutting options.

02/

Accurate Cutting Methods
Laser cuttings offer extreme accuracy compared to other traditional cutting methods. Today, cut width can be extremely small with laser cutting (less than 0.0001 inch) whilst dimensional accuracy is almost as precise (at approximately ± 0.0005 inch). This reduces the need for finishing work and minimizes waste.

03/

Predictable Components
A major advantage of a laser cutting machine is its ability to deliver a minimal heat-affected zone (HAZ). The heat-affected zone results in more reliable parts or components and is often near-exact replicas.

04/

Quick Cutting Methods
Laser-cutting is often faster than other manufacturing processes, especially for more complex cuts. If you compare it to other thermal cutting methods like plasma cutting, laser beats them in speed up to a certain thickness of around 10 mm. each laser cutter is different so everything boils down to the type of machine you have and its power.

05/

Computer-Controlled Automation
A lot of laser cutting is driven by a computer so it requires little effort besides overall observation from a professional. The entire process is extremely automated and often results in lower costs because of it.

06/

Top-Notch Cuts
Depending on how a laser cutter is set up, you're often going to observe possibly a tiny burr on a part. Usually, it's not necessary to remove the burr, but it depends on the material, its thickness and other factors.

Methods And Techniques Of Laser Cutting

A laser cutter is designed to focus energy to a small point to vaporize or melt a material. The method with which this energy is delivered can differ. Listed below are some of the common forms of laser cutting:

Fusion Cutting
Fusion cutting works by using a high-pressure jet of an inert gas like argon or nitrogen to blow out the molten material from the cut created by the laser beam. An inert gas is used so that it does not react with the molten metal. The inert gas also behaves as a shielding gas for the molten edge.

Flame Cutting
Not to be confused with oxy-acetylene cutting, laser flame cutting makes use of oxygen to assist with the cutting process by creating an exothermic oxidation reaction that helps reduce the laser energy requirements. The oxygen is also used to physically blow molten material from the cut. This process is also referred to as reactive laser cutting.

Remote Cutting
Remote cutting also referred to as sublimation or vaporization cutting, is used on very thin or sensitive materials. There is no gas used during cutting and the laser is typically moved using a galvo scanner that directs the laser with a series of mirrors. The laser vaporizes or ablates the material instead of gas blowing it away. Remote cutting can be extremely quick on thin material.

Thermal Stress Fracture
Thermal stress fracture cutting is a technique used to cut material by inducing stress in the base material. An example would be a method employed to cut aluminum nitride where an unfocused beam is used to melt a very thin layer of material on the surface of the part to form aluminum oxide. Aluminum oxide and the base aluminum nitride have different thermal expansion ratios and as the materials cool down at different rates, this causes a stress field that cracks the part along the laser line.

Stealth Dicing
Stealth Dicing is a cutting technique used to place the focal point of the laser inside a material. The laser creates a modified layer internal to the wafer (typically in the production of semiconductors). Once the wafer has been cut, it is expanded using a flexible membrane to cause cracks to propagate through the wafer to separate the individual chips that were internally cut in the material. This technique is mainly used to cut silicon wafers and is preferred to other techniques like diamond wheel cutting which produce inferior chips and require coolant during cutting.

Vector Cutting
Vector cutting is a type of laser cutting used on parts that are made up of clean lines. An example of this would be business advertisement signs. Typically the laser cuts straight through the material.

Laser Rastering
Laser rastering is the most commonly used technique when it comes to engraving an image onto the surface of a material. It works by taking a bitmap image as input and then turning that image into a set of instructions for the laser cutter which then burns the image into the base material.

Difference Between CNC Cutting and Laser Cutting

CNC cutting and laser cutting are both popular methods for cutting materials during parts manufacturing. The two most significant differences are the speed of the cuts and the amount of heat produced. The other main differences between the processes include;

CNC cutting is a manufacturing process whereby material is cut using a series of commands entered into a computer. The cutting tool follows these instructions and cuts the material according to the programmed path. Laser cutting is a manufacturing process that uses a laser beam to cut or engrave materials. The laser beam is focused through a lens system onto the material to be cut or engraved.

CNC cutting machines use a series of rotating blades to cut through material, and can be used to create a wide variety of shapes and sizes. The main benefit of CNC machines is their versatility - they can be used to cut a wide range of materials, including wood, metal, and plastic. On the other side, laser machines can cut materials, like paper, wood, cork, acrylic and foam to certain types of metals.

When compared in terms of pricing CNC cutting is cheaper than laser cutting. The CNC machines can be used to cut a wide range of materials, laser cutters are generally used for cutting super alloys and tough gemstones, which require high precision cutting.

Common Laser Cutting Materials

Laser cutters can be used to cut a wide range of materials. Some of the most commonly cut materials are listed below:

Acrylic (PMMA)
Acrylic produces a smooth cutting edge but an exhaust system is required due to the flammable vapors generated. The gas pressure must be set so that it blows away the vapors while also cooling the cut edge to solidify it. Excessive air pressure will distort the cut edge while it is still molten. Acrylic is also known by the trade name of Perspex® or by its chemical name polymethyl methacrylate.

Carbon Steel/Mild Steel
Carbon steel is a term used to describe a wide range of steels with varying amounts of carbon as their main alloying element. Mild steel is also another type of carbon steel with a carbon percentage of less than 0.3 %. The higher the carbon content the stronger the steel. High-power lasers can cut up to 20–25 mm plate thickness.

Stainless Steel
Stainless steel is classified as a steel alloy containing chromium and/or nickel as its main alloying elements. Stainless steels are resistant to a wide range of chemicals. Stainless steels are readily cut on any laser cutting technology. However, fiber lasers are better suited for cutting stainless steel.

Aluminum
Aluminum is a blanket term used to describe a range of aluminum alloys with different alloying elements and applications. Aluminum has a good strength-to-weight ratio and as such is often used in aerospace applications. Aluminum is a reflective material when melted, making it relatively difficult to cut. While it is possible to cut aluminum with a CO2 laser, it is better to make use of a fiber laser for aluminum cutting.

Brass
Brass is an alloy of copper and zinc with some secondary alloying elements. Brass is corrosion resistant, electrically conductive, and has low friction. Typical applications include low-friction bushes and electrical applications.

Wood
Wood is readily cut with relatively low power (150–800 W) CO2 lasers. However, it is important to have an exhaust system as smoke is generated when laser cutting wood. Natural woods have a grain structure which can result in inconsistent finishes when engraving or cutting. Hardwoods and softwoods can be laser cut.

Hardboard

Hardboard is similar to MDF (Medium Density Fiberboard) but is denser, making it a stronger, more robust choice. The wood fibers are bonded with an adhesive. During cutting, this glue is vaporized. This releases dangerous fumes which require the use of an exhaust system. Hardboard is homogenous, meaning that cutting and engraving are consistent.

Cork

Cork is a soft wooden material that comes from the bark of the cork oak tree and is often used as shoe inserts, non-slip coaster bases, and pinboards. Cork can be laser cut and engraved very easily.

Leather

Leather is a hard-wearing, strong natural material used for shoes, belts, and wallets. Leather can be easily laser-cut and engraved and has high perceived value, especially when used to create personalized laser-cut items. There are also synthetic versions of leather called faux leather. However, some of these may contain PVC which produces corrosive vapors when laser cut.

Felt

Felt is a low-cost, non-woven fabric that is difficult to hand cut but cuts very easily with a laser cutter. Felt can be used for garments, decorative patches, and place mats. It is recommended to use 95–100 % wool felt, as synthetic felt is often made from acrylic and cuts very poorly.

Why Choose Laser Cutting
Laser cutting offers a few distinct benefits. Principal among them is its ability to create extremely precise and accurate parts. Some parts can have tolerances of less than 1mm, which makes the process of laser cutting an efficient method for parts with intricate or complex features. The highly localized nature of laser cutting drastically reduces the risk that the work piece material will warp, and pieces produced via laser cutting oftentimes do not require post-processing treatment or surface finishing.

Metal laser cutting does not require changing tools between operations, allows for more flexibility in design due to lack of fixed tooling, and can be highly automated, minimizing labor costs and shortening production times. since the beam is the only tool that touches the work piece, there’s no mechanical friction causing tool wear in the process.

Laser cutting is extremely common in industrial manufacturing, and is well-suited for producing pieces like automobile bodies, phone cases, and sheet metal. The process also finds extensive applications in the aerospace, medical, and shipbuilding sectors.

How Do Laser Cutting Work
A laser cutting machine works similarly to a CNC machine, but it uses a high power laser. The laser will guide the material or beam through the CNC and optical equipment. The machine will use the CNC, or G-code provided, to cut the material and control the motion.

After the laser beam is focused, the material will melt, vaporize and burn. In addition, when you blow the material with a gas jet, you can obtain a high quality finished edge surface. The laser beam generation takes place in a closed container, where a lamp or electrical discharge stimulates the luminescent material.

The amplification of the luminescent material occurs after internal reflection through a partial mirror. This phenomenon continues until enough energy has accumulated in a coherent monochromatic light stream to allow it to escape. The intensity of the light increases after it has been focused on the working area using a fiber or mirror.

The laser beam diameter is below 0.32 mm at its thinnest edge. Conversely, the width of the incision can potentially be as small as 0.10 mm. this depends on the thickness of the material. If the material is cut with a laser cutter without starting from the edge of the material, then a perforation process is used.

Application of Laser Cutting

Construction Industry

The construction industry builds large-scale projects such as bridges and tunnels, as well as residential and commercial buildings. Structural steel for these projects is often produced by laser cutting. For example, connection plates and base plates are most optimally manufactured by using laser cutting. There are often thousands of these components for a major steel construction project, so laser cutting’s speed and precision give it a big advantage in these applications. Tube laser cutting is also extensively used for structural elements.

Automotive Manufacturing Industry

The global automotive industry is a large consumer of manufacturing output, with over 80 million vehicles produced globally in 2022. The automotive industry requires parts that are precisely manufactured, with very little part-to-part deviation, while also maintaining high production rates to keep up with the pace of vehicle manufacturing. Laser cutting is an ideal technology for meeting the simultaneous requirements of pace, precision, and repeatability. Typical examples of laser-cut components include: sheet metal body elements and textiles for upholstery.

Electronics Industry

Laser cutting is widely used in the electronics industry due to the precision required to process micron-scale electronics components. Silicon wafers are also cut using specialized laser cutting techniques such as fracture-controlled cutting. Other applications include laser engraving information onto components and drilling precise holes in printed circuit boards.

Furniture Industry

The furniture industry makes use of a range of materials such as textiles, wood, and plastics. Laser cutting can cheaply process all of these materials, which is why it is a popular technology in this industry. Textile and padding patterns can be cut for upholstery, and wood can be engraved with various designs. MDF (Medium Density Fiberboard) wood panels can also be cut to produce interesting furniture designs.
