Laser Cutting Basics
What Is Laser Cutting
Laser cutting uses a strong light beam to cut things. It can make shapes and designs that are very exact. You can use it for easy or hard projects. Laser cutting is important in CNC machine tools and laser cutting technology.
How Laser Cutting Works
A computer controls the laser cutter. The machine points a bright light at the material. The laser gets hot and melts, burns, or turns the material into gas. The machine moves in a set path to make the shape you want. Some machines use gases like nitrogen or argon. These gases help keep the edges smooth and clean.
- The laser can cut metal, wood, glass, and plastic.
- The lens makes the beam very sharp for fine cuts.
- Some ways, like fusion cutting, use gas to blow away melted parts for a cleaner edge.
Laser Cutting Applications

Choosing Between CNC and Laser Cutting
Project Needs
Think about what your project needs first. Some projects need tiny, detailed shapes. Others need strong parts with special shapes. Here are some things to think about:
- Laser cutting is best for small, detailed designs. CNC milling is better for hard 3D shapes.
- Laser cutting is fast on thin materials. CNC milling is good for making lots of parts.
- Laser cutting works with many materials, but not all metals. CNC milling works with more types of materials.
- Both ways can cost a lot to buy and use.
Material and Thickness
The kind of material and how thick it is are important. Laser cutting gives smooth edges and is very exact, especially for thin things. Use laser cutting for thin metals and plastics if you want smooth cuts. CNC cutting is better for thick or hard things, like hardwood or composites. If you need to cut big, thick parts, CNC is the best choice.
Budget Considerations
Think about how much money you can spend before you pick. The table below shows some cost differences:
| Cost Factor | CNC Machines | Laser Cutting Machines |
