What Is the Laser Cutting Machine

 

 

A laser cutting machine uses a laser beam to create intricate patterns and designs by heating a material to extreme temperatures. This is accomplished by burning, melting, or vaporizing the workpiece material. The cost of a laser cutter is related to its capabilities, and the number and kinds of features it offers.

What Are the Advantages of Laser Cutting Machine

 

 

The advantages of laser cutting machine are flexibility, precision, repeatability, speed, cost-effectiveness, great quality, contactless cutting, versatility and automation possibilities.
 

Flexibility
Laser cutting machine does not require an exchange of tools for each separate cut. The same setup is suitable for cutting a lot of different shapes within the same material thickness. Also, intricate cuts do not pose any problems.
 

Precision
Accuracy is one of the primary advantages of laser cutting machine when compared to other thermal cutting methods.
An accuracy of +/-0.1 mm gives an opportunity to achieve high precision without any after-treatment. In most cases, such a high standard means that no added tolerances are required.
 

Repeatability
+/- 0.05 mm ensures parts that are pretty much replicas of each other.
 

Speed
Laser cutting machine is a lot quicker than traditional mechanical cutting methods. Especially in the case of more complex cuts.
When comparing it to other thermal cutting methods like plasma or flame cutting, laser beats them in speed up to a certain thickness which is around 10 mm. The exact advantage point boils down to the power of the laser cutter, though.
 

Automation
The job needs little manpower as contemporary laser cutting machine machinery is highly automated. An experienced machine operator still plays a big role in the final quality but the speed of cutting and little need for manual labour result in lower costs compared to other cutting methods.
Many machines even come with feeding systems as well as follow-up conveyors. Of course, such setups make for a higher-priced laser cutting machine machine.
 

Quality
Using the right setup, laser cutters only leave a small burr. Often, it is not necessary to even remove it. Of course, it depends on the material, its thickness and other factors.
Another perk is having a small heat affected zone. As the microstructure along the haz changes, a smaller haz area results in more predictable and reliable parts.
 

Contactless cutting
In case of laser cutting machine, only the beam comes into contact with the material. Therefore, there is no mechanical friction that could wear tools.
 

Versatility
This is probably one of the most important aspects of laser cutting machine's greatness. The versatility manifests itself in two ways.
Laser cutting machine is suitable for a lot of different materials. Among them are different metals, acrylic, mdf, wood, paper, etc. One machine can be configured to perform different jobs. Of course, the ability to cut some of these materials depends on the power of your machine.

 

Parameters Which Influence the Laser Cutting Machine Process

Focus position and focal diameter
The focus position influences the irradiance and form of the kerf on the workpiece. The focal diameter determines the gap width as well as the form of the kerf.
 

Laser power
So that the processing threshold – the point at which the material begins to melt – is exceeded, a specific amount of energy per surface area unit is required. This is defined as: Energy per surface area unit = irradiance x exposure time on the workpiece.
 

Nozzle diameter
Choosing the right nozzle is crucial for part quality. The form of the gas beam as well a the gas quantity are determined by the diameter of the nozzle.
 

Operating mode
Continuous wave operation or pulsing – the operating mode allows you to control whether the laser energy is to hit the workpiece continuously or with interruptions.
 

Cutting speed
The respective cutting task and the material to be processed determine the cutting speed. As a basic rule: The more laser power that is provided, the faster the cutting can be carried out. Additionally, the cutting speed is reduced with increasing material thickness. If the speed for the respective material has been set too high or too low, increased surface roughness and burr formation can occur as a result.

 

Degree of polarisation
Nearly all CO2 lasers deliver linear polarised laser light. If contours are cut, the cutting result changes with the cutting direction: If the light oscillates parallel to the cutting direction, the edge will be smooth. If the light oscillates perpendicular to the cutting direction, this creates a burr. This is why linear polarised laser light is often switched over to circular polarised. The degree of polarisation determines how well the target circular polarisation was reached, and is decisive for cutting quality. Polarisation must not be changed for solid-state lasers; it delivers direction-independent cutting results.
 

Cutting gases and cutting pressures
Different process gases are used depending on the cutting procedure; they are driven through the kerf at varying pressures. Argon and nitrogen as cutting gas, for example, have the advantage that they do not react to the melted metal in the kerf, while at the same time shielding the cutting area from the environment.


Laser cutting machine with a gas mixture
Burrs in mild steel and aluminium can be reduced when combining high laser power with the application of a gas mixture of nitrogen and oxygen. The improvement in part quality depends on the material type, material alloy and material quality in thick sheet ranges between six to twelve millimetres.

 

What Are the Factors That Affect the Prices of Laser Cutting Machines
 

The list below describes some of the factors that affect the prices of laser cutting machines:

Type of laser

The equipment used to generate the laser light beam in the three main types of laser cutting systems differs significantly in complexity and, consequently, price.

Laser power

As the rated power of the laser beam increases, the cost of the components to handle the higher energy levels increases.

Workpiece thickness

Cutting thicker material requires higher-power lasers. High-power lasers require heavier-duty components and are more expensive than low-power machines.

Cutting speed

Cutting speed impacts price because the motors that drive the position of the laser cutter head become more expensive as speed requirements increase.

Workpiece material

Harder materials such as metals and highly reflective materials like stainless steel require specialized equipment for laser cutting to be successful.

Work table size

Larger work table size leads to higher prices due to the need for more raw materials and higher power equipment to build and operate larger machines.

 

Techniques of Laser Cutting Machine

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

 

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 machine.

 

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 machine 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.

 

Main Components Of Laser Cutting Machines

 

Laser cutting machines 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.

 

 

How Does Laser Cutting Machine 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 machine 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.

Q: What is the laser cutting process of laser cutting machine?

A: Laser cutting is a slitting process with which it is possible to cut metallic and non-metallic raw materials of different material thicknesses. This is based around a laser beam which is guided, formed, and bundled. When it hits the workpiece, the material heats up to the extent that it melts or vaporises.

Q: What can a laser cutting machine not do?

A: This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter.

Q: Why is laser cutting machine so expensive?

A: Laser Power: As the rated power of the laser beam increases, the cost of the components to handle the higher energy levels increases. Workpiece Thickness: Cutting thicker material requires higher-power lasers. High-power lasers require heavier-duty components and are more expensive than low-power machines.

Q: How long does it take for laser cutting machine to perform laser cutting?

A: Laser cutters can be very quick, and can churn out designed parts in just a few minutes. Like 3D printers, laser cutters are rapid prototyping machines; they allow designers to quickly and cheaply iterate on their designs before they produce products on a larger scale.

Q: What jobs do people use laser cutting machines to do?

A: Laser cutting machine is often employed in the metalworking industry to cut metal into desired shapes. Some common products that are produced are: beams, columns, pipes, tubing, and sheet metal. These products can be used in a variety of industries, such as construction, automotive, and aerospace.

Q: Is there a fire hazard in laser cutting machine?

A: A tremendous amount of heat is applied to the material being cut. This build up of heat can cause significant fire risk and the machine should always be monitored. Always keep a properly maintained and inspected fire extinguisher on hand.

Q: How long do laser cutting machines last?

A: Apart from that, most of the laser in the market have a life around 30,000 hours, which is a lay man's language is 15 years of proper usage. Further, one can expect a good 100,000 hours life of fiber lasers, which roughly translates to 45 years of machine use.

Q: What do I need to know about laser cutting machine?

A: A laser cutter is a prototyping and manufacturing tool used primarily by engineers, designers, and artists to cut and etch into flat material. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and geometries specified by designers.

Q: Can laser cutting machines break and cut?

A: Fracture-controlled cutting is also known as thermal stress cracking. It is applied when cutting brittle materials. When uncontrolled force or temperature is applied, brittle materials tend to break into pieces. Fracture-controlled cutting focuses a very narrow laser beam on a small workpiece surface. It creates a thermal gradient that cracks the workpiece in that location. The laser then moves in a very fast and controlled manner to spread the crack along the cut.
Fracture-controlled cutting is commonly applied when cutting glass and ceramics. The laser is not passing completely through the material thickness. Only a portion of the thickness is cut and the rest separates due to cracking.

Q: What precautions should be taken during laser cutting machine?

A: Never operate system unattended. Properly maintained fire extinguisher should always be in the area. Always keep the area around cutter free of debris, clutter, and flammable materials. Keep interior of the laser cutter clean and free of debris.

Q: Do laser cutting machines use a lot of electricity?

A: The power consumption of a laser is a common question before purchasing a laser. Many customers cannot estimate how much the operation of a laser will affect their electricity bill. In practice, however, the power requirement of a laser is often less than that of a fan heater or an air conditioning system.

Q: Do laser cutting machines need maintenance?

A: Maintaining a CO2 laser is easy, but important to keep your machine safe and operating well for optimal performance. A wide range of parts can go wrong if you don't take the correct measures to keep your machine in good condition, so it's always worth doing regular servicing to ensure peak performance.

Q: How does laser cutting machine work?

Q: What PPE is required for laser cutting machine?

A: Personal Protective Equipment (PPE) for laser cutting includes items such as: coveralls, head covers, and face shields. The hazards in laser cutting are rarely "whole body", but all machining processes tend to produce contaminants that are best excluded from direct contact with skin, clothing, and hair.

Q: What size laser cutting machinedo I need?

A: If you're working with thin materials like paper or cardboard, a lower-wattage laser tube around 40 watts would be a great choice. However, if you want to cut through thicker materials like 2mm - 6mm wood or acrylics, we recommend a higher-wattage laser tube around 60w - 100w.

Q: How thick of wood can a laser cutting machine cut through?

A: Hardwoods can be sourced in a wide range of thicknesses but may need multiple passes to cut. In general, a 45 W laser at full power and a slow feed will cut ¼"-thick slices of most hardwoods.

Q: How to choose the right laser cutting machine?

A: Before you buy, determine how much power you need. If you want to buy a laser cutter for artistic purposes, you can choose a laser cutter with a lower power. If you may need to penetrate or cut some thick metal for manufacturing purposes, you need to choose a higher power laser cutter.

Q: How do you maintain a laser cutting machine?

A: Laser machine maintenance checklist
Clean lens with acetone/alcohol.
Oil runners with light oil.
Clean machine bed.
