Laser cutting process

What is laser cutting?

Laser cutting is a process where a high power laser light beam is used to cut through materials. The material either melts, burns or vaporizes by the laser beam, leaving a clean edge. Laser cutting is a precise process and can be used to cut simple and complex shapes, for metal cutting or laser engraving.

Laser metal cutting is the new standard for cutting 2D parts from large sheets of raw materials. Online laser cutting services offer a convenient way to have materials cut by a laser. Laser-cutting steel is one of the most popular applications of this technology. A laser cutting company can cut many materials for sheet metal fabrication of small and large production runs.

Types of Lasers used in Laser Cutting

Mainly four types of lasers are used for cutting: CO2, fiber, neodymium (Nd), and Nd:YAG lasers. CO2 lasers are the most common lasers due to their high energy and efficiency. CO2 lasers are suitable for use with engraving and cutting.

eMachineShop primarily uses fiber laser cutters since they offer several advantages over other types of laser cutters, such as increased speed, increased accuracy, and lower power consumption. Additionally, fiber lasers are much more durable and require less maintenance than other types of laser cutters. Fiber lasers also generate less heat during the cutting process, which eliminates the need for cooling systems. These factors and benefits make them ideal for custom machining since they are accurate, reliable, and cost-effective for the machine shop, resulting in lower manufacturing costs for part designers and engineers.

Fiber Laser Vs CO2 for Laser Cutting Metal

A high powered laser is necessary to vaporize surface material when cutting metals. Fiber lasers are ideal for cutting and marking metals due to their increased cutting capability and high absorption rate. For metal laser cutting services, fiber laser is unparalleled.

Benefits of CNC Laser Cutting

Laser cutting machine technology

Among the many benefits of a high powered CNC laser cutting service are flexibility and precision, cost-effectiveness, and great quality. Laser metal cutting offers faster processing times and accuracy though it is more difficult to cut thicker materials, which may be more suitable for waterjet cutting. Additionally, many industries, such as tool machining, electronics, automotive, and aerospace, use laser cutting service for various purposes. Here are some of the benefits that a laser machine can provide:

Accuracy

The laser cutter produces a focused laser beam that allows precise cutting at high speed and minimal cost.

Drilling speed

Considering there is no tool positioned against the workpiece, drilling speed only depends on the optical system’s motion.

Non-contact technique

Compared to conventional drilling, laser engraving and cutting have no contact with the surface. Over time drill bits can become dull, making the machining process slow and less productive. The heat produced by the drill can distort the material and change its mechanical properties.

Able to cut difficult materials

The laser machine can cut through a wide range of difficult materials, including steel superalloys and titanium. Laser cutting service includes metal cutting, ceramics, wood and some plastics.

Minimal burrs produced

Even a high quality laser cutting service tends to develop some burrs when the machine finishes the cut.

No residual stress

Since assist gas blows away most of the molten material, minimal residual stresses are created along the edges. This results in a mechanically stable and clean cut.

Economics

Metal laser cutting is fast and efficient which makes it one of the most cost-effective processes.

Cutting vs. Engraving vs. Marking

A laser cutting company usually offers all three services at once: cut, engrave, and mark. In fact, the only difference between these operations is how deep the laser goes and how it changes the overall appearance of the material. In laser cutting, the heat from the laser cuts through materials while laser marking discolors only the surface of the material, while engraving removes a portion of the material.

What is laser engraving?

The technology of laser engraving machines has drastically improved since the invention of lasers. Engraving involves making a shallow cut into a material to create fine details in custom projects. Laser engravers burn and permanently mark surfaces using heat. An engraving service is often used for adding text and logos. Laser marking methods include laser engraving, which is commonly used on metals, plastics, and stone, carbonizing, which is often used to mark a wide range of materials, such as leather, wood, and paper, and foaming, which is used on light-colored materials.

Laser Cutting Materials

CNC machine shops offer high quality CNC laser cutting services for cutting a wide range of available materials including aluminum, stainless steel, titanium, brass, copper, sheet metal, and most other metals plus wood and a variety of different plastics.

Laser Cutting Acrylic

One of the most efficient and accurate ways of cutting acrylic sheets is achieved by CNC laser cutting machines, creating complex and intricate shapes and designs. An advantage of laser cutting acrylic is that the sheet does not bend. In addition, laser cutting produces no shavings and can cut intricate shapes and various thicknesses. Acrylic, also known as plexiglass, is a transparent plastic material similar to glass, yet less brittle and less prone to breakage. There are many types of acrylic available, ranging in size and color. One of the advantages of laser cut acrylic is its low cost. Acrylic is seen in various applications such as windows and lighting equipment. Types of Acrylic:

  • Cast Acrylic and Extruded Acrylic are two types of acrylic which vary in how they are made. They contain the same chemical properties but produce different results when cut using a laser cutting machine.
  • Cast Acrylic – This type of acrylic is created by pouring melted acrylic into a mold, which sets the shape with the desired thickness and size. Cast acrylic is commonly used for engraving in various products, however it is not the ideal choice for cutting.
  • Extruded Acrylic – Extruded Acrylic is made using hot acrylic sheets, which are mechanically pressed under rollers. This type of acrylic is rolled until a desired thickness level is reached. This type of acrylic is more cost effective and is considered the ideal choice for laser cutting machines but is not the ideal choice for engraving since engraving results in an unfrosted look.

Laser Cutting Wood

A wood laser cutter is affordable and laser cutting wood is easily achieved with the proper equipment. Some of the most popular types of wood used for laser cutting and laser engraving are plywood, MDF, and veneer. Other types of wood commonly used for laser cutting are basswood, birch laser plywood, alder, poplar, cedar, and pinewood.

  • Advantages of Laser Cutting Wood – CNC laser cutters are reliable for laser cutting wood. Their level of repeatability and precision makes them ideal for laser cutting wood, since they produce edges without burrs on flat wood surfaces. Additional advantages of laser cutting wood include high precision and high speed and no material contamination. Various applications and industries rely on laser cut wood.
  • Wood edge – CO2 lasers have various power settings though an edge burn is often produced. Woods that are harder, such as oak, tend to have a lower resin level. To achieve less burn and a lighter cut, wood with a lower resin level can be used.
  • Hardwood vs Softwood – The main difference between hardwood and softwood is that hardwood is heavier and darker and can last for decades. It is weather-resistant as well. Softwood is lighter and needs to be treated for weather resistance though once it is treated it can last for a decade.

  • Can a laser cutter be used on plywood? Plywood is essentially thin layers of wood veneer. The layers are pressed together, making plywood a stable wood product. The results achieved by laser cutting plywood depend on the quality of the plywood. High-quality plywood has increased axial strength and is rotated every 45 degrees. Birch and bamboo laser plywood are among the two types of plywood most suitable for laser cutting. Birch is a reliable and easy-to-use plywood that cuts reliably and smoothly.
  • Laser Engraved Wood – The use of a CNC laser cutter has transformed wood work, allowing for intricately engraved designs that were previously impossible to achieve with manual machining or other services.

Laser Cut Steel

Steel requires a machine that has the capacity to cut at high power settings. Stainless steel and other steel alloys are commonly cut using CO2 and fiber lasers since these lasers are capable of achieving high power cuts. When laser cutting steel, the thickness of the sheet correlates to the amount of power required to make cuts in the durable metal. Nd: YAG lasers are not ideal for cutting steel over 20 millimeters thick though combining them with an oxygen assisted gas and an optical fiber enhancer can boost their steel-cutting capacity.

Laser Cut Metal

One of the key advantages of laser cutting is that it is capable of cutting essentially any metal including metals ranging in thickness. Metals are ductile, malleable, and reflective materials distinguished by their high rate of thermal and electrical conductivity. CNC laser cutters can cut most grades of stainless steel, mild steel, cold rolled steel, aluminum, titanium, brass, and copper.

Laser Cut Aluminum

Laser cutting is the ideal choice when it comes to cutting aluminum since laser cutting results in minimal burrs, high speed and accuracy. The level of cutting difficulty is determined by the aluminum grade. This means that higher grades of aluminum are easier to cut, since they contain more alloying elements. Since aluminum is quite reflective naturally, the laser beam can bounce back from the aluminum surface, resulting in damage to the laser cutting machine. This is an issue for CO2 lasers which contain mirrors. This is mostly challenging when cutting pure aluminum. Aluminum alloys are mixed with additional metals such as magnesium and copper, which makes them less reflective, and therefore easier to cut using an industrial CNC laser cutting machine. A fiber laser cutter is the most suitable option for cutting aluminum due to its capacity for cutting reflective materials and its high power output. Since a higher power output is necessary for laser cutting aluminum, CO2 lasers are not the best choice as they have a smaller power output compared to fiber lasers. Their wavelength is not ideal when cutting nonferrous material and they are more susceptible to the aluminum’s reflective nature.

Secondary Machining for Laser Cut CNC Parts

Many CAD model designers utilize secondary machining processes with laser cutting such as metal bending, tapping, and surface finishing. For metal bending, the CAD model designer can indicate the placement and desired angle of bends or tapping instructions in a laser cut part design file. After the custom parts have finished production they are sent to hydraulic press brakes for bending or to tapping machines. The majority of materials typically used in CNC laser cutting are also able to get surface finishing such as anodizing, powder coating, painting, polishing, or media blasting. This allows the custom laser cut parts to have a uniform look, added functionality, corrosion protection, or just be more cosmetically appealing. The use of these secondary machining services with laser cutting provides CAD designers more capabilities to get their custom parts into production.

Laser Cutting versus Waterjet Cutting

While laser cutting is one of the most efficient ways to create complex and intricate 2D parts, there are some limitations within this process and certain design specifications are better suited for waterjet cutting. When it comes to knowing when to use laser cutting or waterjet cutting, it is important to take into consideration the size of the parts being produced and most importantly, the thickness of the material. For thicker metal cuts, waterjet cutting is the standard machining operation instead of using a laser cutter service due to its industrial strength, accuracy, and power capacity.

The other main difference between laser cutting and waterjet cutting is the cost. Laser cutting services tend to be more cost-effective for smaller parts and projects, while waterjet cutting services are more cost-effective for larger parts and projects. Laser cutting machines need less maintenance and less power to operate than a waterjet cutting machine.

Overall, both laser cutting services and waterjet cutting services have their advantages and disadvantages, and it is important to consider the project before deciding which one is the best choice. Both services provide custom and precise work for a variety of industrial needs, and both can be used to create intricate projects. Depending on the size and thickness of the material and the intricacy of the design, either service can be the best choice for a given project.

Every aspect of dealing with eMachineShop was a pleasure. Just received my parts; and I could not be happier. Exactly as I imagined them! Great work: from the easy-to-use online CAD app, to the assistance given by the team prior to ordering, to the actual parts. I used their browser CAD to design my piece - their tutorial and templates get you going very quickly. I submitted it for a quote, and one of the team contacted me to discuss my choice of material and manufacturing process. Turns out I'd made a poor choice. The team set me straight and we proceeded to the build. I received my parts this morning and they are perfect. I was able to complete my project with no further machining, finishing, polishing etc. As an apartment-dweller - with no access to a machine shop - this was an incredible service. The alternative would be to rent a workspace, buy waaaaay more material than I needed, cut it, shape it, drill, tap and then test. Would 100% use this service again, and recommend them to others who need precision pieces manufactured.

Frequently Asked Questions

Q: Can you laser cut polycarbonate?

A: Polycarbonate does not cut well in laser cutters. It tends to melt rather than vaporize, and has a higher probability of catching fire and leaving behind deposits. Acrylic or metal are more common choices.

Q: How to laser cut acrylic?

A: Acrylic is a versatile material that can be cut using a laser cutter to create custom-cut acrylic shapes and designs. General guidelines are not to leave the machine unattended and use a low-power setting. Make sure your material is raised off the surface it will be sitting on by at least one inch.

Q: Can you laser cut carbon fiber?

A: We do not recommend using a laser cutter to cut carbon fiber. This is because the laser cutter will burn the epoxy before the laser can cut through the fibers, resulting in a burned cut line, not to mention toxic fumes. Other processes are better for carbon fiber.
