Laser Cutting

There are several variables that influence the cutting process of a laser, including its depth of focus, reflectivity, and types of lasers. This article will cover the basics of laser cutting as well as some of the common types and their costs. This will help you make an informed decision when deciding whether to use laser cutting as a primary or secondary method of cutting. In addition, you’ll learn about the cost and types of lasers available for your project.

Reflectivity affects laser cutting process

Materials like copper have low reflectivity, but the reflection of the beam changes when the material is warm or molten. In a molten state, copper has 70 percent reflectivity. Because of this, molten copper absorbs more laser energy. It is important to check the material’s reflectivity before starting the cutting process. Below, you will find a comparison of different types of materials. Read on to find out which material is the most reflective, and how it affects laser cutting.

Depth of focus governs laser cutting process

A laser cutter works by focusing a laser beam using a lens or concave mirror to a small spot, where its power density is sufficient to create the desired cut. This spot is called the depth of focus and is the distance over which the focused area does not increase in size by more than 50 percent. A small focus area can only produce a fine detail. On the other hand, a thick material will require a large focus area.

Types of lasers

The four main types of lasers used for laser cutting include gas lasers, solid state and broadband liquid lasers. Broadband liquid lasers are preferred over solid state lasers because of their higher monochromaticity. Both of these types of lasers can produce a similar cut. Broadband liquid lasers are best suited for cutting thin metals, such as titanium. They can be used in laser cutting processes for both wood and metal.

Cost of laser cutting

The cost of laser cutting varies depending on what materials you want to work with. Some materials are easily processed while others require a lot more time and resources. Obviously, you don’t want to compromise on quality. The lead time and shipping requirements for your project also play a factor. If you need a product fast, order a prototype first, so you can modify it as necessary. Otherwise, ordering a large number of laser-cut products may result in disappointment and additional costs.

Material selection for laser cutting

The most important considerations in material selection for laser cutting include the desired cutting edge shape, the desired power level, the wavelength of the laser, and the type of lens used. This will also influence how and where the material is supported during cutting. These supports include a cutting table, pin table, rotary fixture, and gas assist or air filtration. For a more flexible material, you can try using a combination of these supports.
