CNC laser cutter is the equipment used to mark, engrave or cut a material to form custom shapes with the help of a focused and high-powered laser beam. It is highly accurate when cutting small holes and intricate shapes. As the most fundamental and widely prevalent technique in the market, laser cutting has various advantages over other conventional methods. It provides power and precision for large-scale production results with several benefits for a manufacturer.
Benefits of Laser Cutting:
• Flexibility: The same tool can be used simultaneously to cut a variety of shapes.
• Speed: Laser cutting is a faster method of cutting than the traditional mechanical technique. This accounts for the lower cost.
• Contactless Cutting: There is no possibility of tool damage such as wear and tear in this type of cutting as only the beam comes in contact with the material.
• Repeatability: The parts are produced at the rate of +/-0.55mm.
• Versatility: This technique can be used for many types of materials such as aluminum, stainless steel, and iron.
• Automation: Manual power is less compared to traditional methods for laser cutting as the machinery is automated.
Trends in Laser Cutting:
• Combination of 3D printing and CNC: Even though CNC and 3D printing do different operations such as cutting out shapes and building three-dimensional models respectively, manufacturers are adopting a hybrid technique incorporating the two. They have created ways to combine both technologies to generate an accurate solution that is effective as well. One way is to make prototypes with 3D printing and fabricate the product using CNC.
• Artificial Intelligence Maintenance: AI is growing exponentially, improving the precision of machines due to its self-healing and self-diagnostic properties. Incorporating AI into CNC can help achieve a longer tool lifespan, increase production, and enhance efficiency. For instance, if a machine is at fault the AI can sound an alarm, stop the process, point out the failed module, and turn on the spare equipment.
• Virtual Reality: Using virtual reality in the design stage makes it possible to evaluate the machines before it is manufactured. Following this approach would help in identifying the errors at an earlier stage in production.
• Multiple Axis Machines: Due to the high demands of CNC techniques, manufacturers have been building 3-, 4-, and 5-axis models for quite some time. However, the cost and difficulty of manufacturing the same were tackled quite recently.
• Opportunities to learn CNC: The surge in demand for this technology gave the manufacturers the biggest challenge, a shortage of skilled operators. Various companies saw this opportunity and started providing online training that potential candidates could attend in the comfort of their homes.
The trends in CNC keep changing with the constant advancements in technology. It is a fast-growing industry that will continue to be in high demand.
