However, navigating the expansive landscape of available options can indeed be daunting. How do you go about selecting the ideal Laser Cutting robot that perfectly aligns with your specific operational requirements and strategic objectives? 

By the end of this guide, you’ll possess an understanding of the Laser Cutting robot landscape and the tools necessary to select a robot that aligns seamlessly with your unique production demands and business goals.

Types of Laser Cutting robots

Before you start busting out your favorite manufacturer’s catalog, you’ll want to start with choosing the correct type of robot. The major types of Laser Cutting robots include:

Gantry-mounted robots, or “Cartesian” robots, feature a track system which supports and guides the robot arm along multiple axes. This design offers an extended work area, making it ideal for cutting larger materials or executing cuts over a significant area. The integration of robotics in Gantry-mounted systems enhances the speed and accuracy of cuts, enabling manufacturers to tackle large-scale projects with unparalleled efficiency.

Articulated robots emulate the dexterity and flexibility of human arms, making them adept at intricate and complex laser cutting tasks. These robots are capable of executing cuts from various angles and orientations, allowing them to access hard-to-reach areas and intricate contours. With the addition of robotics, Articulated robots can navigate with precision and adapt to the ever-changing demands of modern manufacturing. 

Collaborative robots, or Cobots, are a safety-focused form of an Articulated robot. In the context of laser cutting, Collaborative robots can perform precise cuts in close proximity with your human staff and with minimal need for safety equipment, ideal for busy production lines where your robot will be handing off parts to humans for further processing. Specifically, Cobots come equipped with features like collision avoidance, emergency halting and even foreign object detection.

Key considerations when choosing a Laser Cutting robot 

Whichever type of robot you choose, there are a few specific considerations you’ll want to keep in mind when picking a particular model for your laser cutting application:

Robotic integration and compatibility: Evaluate whether the robot is compatible with your current production setup, including conveyors, workstations, and auxiliary equipment. You’ll want to be sure of how you’ll get parts to the robot and what length of reach your chosen robot needs to have. If you want the robot to directly interface with surrounding equipment, such as your existing laser source or a conveyor for controlling the flow of parts.

Programming and control software: Choose a robot that offers user-friendly software, ideally with visual programming options that simplify the creation of intricate cutting paths and patterns. You’ll want to make sure your team can program the robot and calibrate the cuts, rather than have to hire a consultant programmer every time your production line changes. 

End-effector flexibility: The end-effector, meaning the tool attached to the robot, is the bridge between the robot and the material being cut. If you’re a high-mix shop, opt for a robot that supports a variety of end-effectors, allowing you to effortlessly switch between different cutting tools based on material type, thickness, and intricacy of cuts. Consider robots that offer quick-change mechanisms for end-effectors, reducing downtime and maximizing versatility.

Understanding end-effectors for Laser Cutting robots

Speaking of end-effectors, let’s explore these in more detail. A robot without an end-effector is like an arm without a hand, so choosing the right one is just as important - if not more so - than choosing the robot itself. 

End-effectors are often manufactured by a separate company from your chosen robot arm and have their own considerations. Here are the main things you need to know:

Cutting heads: Unsurprisingly, the main end-effector you’ll need for your robot is a specialized cutting head. The best end-effectors often incorporate features such as adjustable focus, lens protection, and dynamic beam control to adapt to different materials and cutting requirements. You’ll need to power the cutting head separately from your arm and ensure the payload of the robot is high enough to lift the end-effector and any attached cabling.

Autofocus: One step up from a cutting head with an adjustable focus is one with an automatic focus. These clever end-effectors can sense and adjust to compensate for inertia without the need for human intervention. These end-effectors can vertically move their beam unit without requiring the robot arm to move, which can speed up cycle times and drastically reduce the complexity of programming.

Vision systems: Vision systems, equipped with cameras and sensors, provide real-time feedback on material positioning and alignment. These end-effectors enable the robot to adjust its movement and cutting paths based on visual data, ensuring precise cuts even on irregular or misaligned surfaces. This is suitable for complex cuts where autofocus is too imprecise. 

As we mentioned above some end-effectors go a step further, incorporating tool changers that facilitate seamless transitions between laser sources of the inclusion of additional tools, such as plasma cutters. It’s essential to ensure that any considered end-effector possesses the requisite capacity to manage the dimensions and weight of the materials earmarked for cutting.

Use of the robot in 3D laser cutting - BLM GROUP Blog

A 3D laser cutting robot system is developed to laser cut three-dimensional profiles and consists of an industrial robot (usually with 6 axes) with a 3D laser cutting head mounted at the end of the robotic arm.

Example of deep drawn material cut with LT360

Besides the robot and the 3D laser cutting head, the system needs other components:

  • Laser source
  • Assist gas delivery system
  • Enclosure

Laser source

The most common type of laser technology for this application is fiber laser for two main reasons:

The company is the world’s best Robotic 3D Laser Cutting Machine supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

  1. Laser beam transport along an articulated system, such as a 6-axis robot, is easier if carried out through an optical fiber.
  2. Machined parts (usually bent tubes, molded, hydroformed or deep-drawn parts) have limited thickness, usually less than 6 mm (.24”), and are made of a wide variety of materials: stainless steel, copper alloys, aluminum, titanium, etc.

The thinner material thickness of 3D components requires a lower power laser when compared to sheet metal cutting systems. In general, for a 3D laser cutting machine, both with robot or 5-axis CNC, the power source is usually from 1 kW to 3 kW.

Assist gas delivery system

A laser cutting robot system also needs a system to deliver assist gas.

It is a good rule to choose manufacturers that allow more than one line for different types of gas: nitrogen, oxygen, etc.

Enclosure

The laser wavelength of fiber laser sources is different than CO2 sources and requires certain safety precautions. As a matter of fact, when processing material with a fiber laser, a certified safety enclosure is needed for operator protection.

Companies dedicate time and attention in the design of standardized enclosures. Pre-engineered solutions benefit the end-user with lower costs, quicker delivery, and faster installation times.

The initial investment cost are lower, when compared to customized robotic 3D laser cutting systems, and allow you to start-up production sooner. Whereas, customized systems tend to have longer leads times and higher costs as a result of the design engineering time and safety certification requirements.

Other components necessary to the system are: the chiller, to cool the laser source, and the fume extractor, that sometimes must be equipped with an upstream distribution system for fume and dust removal.

Robotized laser cutting systems consist of many components: that is why, with the intent of reducing footprint, some manufacturers are developing systems which are extremely compact, but also highly flexible.

Sectors where a 3D laser cutting robot can be used

Similarly to the 5-axis laser cutting systems, the 3D laser cutting robots are becoming widely used in many application sectors.

Even if application sectors for both these technologies are virtually the same, there are real differences.

Automotive, motorcycle and aerospace

In sectors like automotive, motorcycle and aerospace, 3D modelling and FEM analysis has changed how parts are designed and manufactured. A considerable number of conventional mechanical parts have been replaced by complex three-dimensional profiles such as bent, hydroformed, deep-drawn, molded, die-cast tubes or pre-welded assemblies. There is a strong focus to design lighter-weight components and reduce number of parts an assembly is made up of, in order to yield better material utilization and achieve increased performance.

Using a robot on these type of parts could be a valid solution to the problem of the geometrical complexity of the part: thanks to the 6 axes of the robot, the 3D laser cutting head can freely reach any point on the part.

Contractors

Another sector where 3D laser cutting systems may be used is that of contractors.
Actually, the use of robots in this sector is still very limited, mainly due to a production flexibility problem, an essential quality for a contractor.

In order to have a 3D laser cutting robot system suitable for this type of production it should be easily programmable, have the ability to set up the part program directly in the machine simply and quickly and the system should be easily accessible.

Taking these factors into consideration, some machine tool and 3D laser cutting system manufacturers have developed compact and turnkey systems for 3D laser cutting with robots.

A robotic solution is able to perform highly complex cutting processes and change production rapidly, providing the flexibility contractors need.

Can a laser cutting robot system offer flexibility? And how?

How to choose a laser cutting robot system which is also flexible? Take into account the following key points:

ARTCUT: CAM software for programming laser cutting on 3D workpieces

Programming software

To quickly program a new operation, the software must be able to:

  • Program a new production batch off-line, while the machine is processing a different batch.
  • Import 3D files from third-party CAD software.
  • Quickly identify cutting paths.
  • Identify and solve potential constraints and improve the work cycle in a simple and intuitive manner.
  • Simulate your work cycle and start production safely.

Setting up directly in machine

Once the program has been developed offline, it is assigned to the machine post-processor. A flexible system allows you to carry out many changes directly in machine: this is essential to develop prototypes or small batch productions.

A flexible laser cutting system automatically optimizes cutting parameters based on a number of factors, including cutting speed, thickness, type of material to be cut, and 3D laser cutting head inclination.

How can a greater freedom improve your production?

The 6 degrees of freedom of the robot

One of the strengths of using a robot is the greater freedom offered by its 6 axes of motion. This allows the system to:

  • Increase the feasibility of the parts as the 6 axes allow the 3D laser head to reach any direction in space.
  • Increase speed because 6 axes increase the number of possible rapid paths and reduce part repositioning.

Then, there are solutions that provide a much greater number of freedom levels. The most efficient is with the use of a second robot to manipulate the part, an ideal solution when you need to perform 3D laser cutting on hydroformed parts, bent tubes or other type of closed profiles without manual repositioning.

What are the selection criteria for a 3D laser cutting robot system?

Below is a list of key elements that will help you understand if a 3D laser cutting robot system is suitable for you.

Are you working with complex three-dimensional profiles?

Molded, deep-drawn, hydroformed, die cast parts, bent and hydroformed tubes and any three-dimensional complex profiles are suitable for a 3D laser cutting robot system.

Part volumes shouldn’t be your only consideration

To justify the costs of a 3D laser cutting robot system and accelerate ROI, it is necessary to evaluate the specific production volumes carefully.

This evaluation should also take into account that flexibility offered by the system plays a key role.

Consider programming and set-up time. Choosing a system that allows you to start production rapidly with an offline CAM software and intuitive machine interface, is important to save time.

A flexible system will allow you to be more competitive, to reduce machine production set-up and estimate times. Even if the single production batches are small, you can rapidly change production or develop new prototypes, thus obtaining, in a relatively short period, the volumes necessary for the return on investment.
