What Is A CNC Router?

A CNC (Computer Numerical Control) machine or router is a computer controlled machine that cuts out shapes from materials such as wood, plastic, metal, and glass.

The CNC router allows you to cut intricate designs into almost anything.

What is a CNC Router

A CNC router has a large base where the material is placed. Then, the user uses a tool called a bit to carve out the design. This tool is attached to a spindle that spins at high speeds.

As the spindle rotates, it moves back and forth across the surface of the material.

CNC routers are great tools for hobbyists who want to create their own custom furniture, jewelry, and other items.

They also come in handy for professionals who need to produce accurate parts for industrial applications.

How Do I Use A CNC Router?

The first step when using a CNC router is to set up your software. There are many different types of software available, each with its own benefits and drawbacks.

Once you have chosen which one you like best, you can start creating your projects.

The next step is to decide what type of project you would like to make. You can use a CNC router to create everything from simple pieces to complex 3D models.

Some people prefer to work on small projects while others enjoy making larger pieces.

You will then be able to select the size of your project. It’s important to consider how much space you have before purchasing a CNC router. If you don’t have enough room, look for a smaller model.

On the other hand, if you plan to make a big piece, you may want to invest in a bigger CNC router.

Once you have selected all of these options, you can begin cutting out your project by selecting the location of the tool path. You can either draw the path yourself or let the software do it automatically.

After you have created the path, you can move onto the actual cutting.

When you are ready to cut, you simply place the material on the table and attach the appropriate accessories. Most CNC routers include a vise to hold down the material while you cut.

However, some require additional attachments.

After you have completed your project, you will need to clean up any remaining bits of material. To remove the dust, you should wipe down the entire area around the CNC router.

What Types Of Materials Can Be Cut With A CNC Router?

There are many different materials that can be used with a CNC router. These include wood, plastics, metals, and even ceramics. Each material offers unique advantages and disadvantages.


Wood is an easy material to work with because it doesn’t splinter or crack easily. However, wood requires a lot of maintenance and care. For this reason, most people stick to working with wood only after they have mastered the basics of using a CNC router.


Plastics are another popular choice among hobbyists. Because they are relatively inexpensive, they are often the first material that new users try.

In addition, they are very durable and easy to shape. Unfortunately, they are not as strong as wood and tend to warp over time.


Metal is a great option for those looking to make something sturdy. While metal does take more effort than plastic, it is still easier to use than wood. The downside is that it tends to rust over time.


Ceramic is a hard material that is ideal for making intricate designs. It is extremely durable and resistant to wear and tear. This makes it perfect for high-end projects. However, ceramic is difficult to machine and is prone to cracking.

What Are The Different Types Of CNC Routers Available?

CNC routers come in several different sizes and shapes. They range from tiny handheld tools to large industrial machines. Here are just a few of the different types of CNC routers available today:


Handheld CNC routers are designed specifically for home use. They are compact and portable, making them easy to transport. Many of these units also feature multiple tools so that you can complete multiple tasks at once.

Industrial Machines 

Large industrial machines are designed to handle larger pieces of material. Some of these models are capable of producing parts that weigh hundreds of pounds.

Desktop Units 

Desktop CNC routers are designed to fit on a desk. They are usually equipped with a small motor and a single tool head. Although desktop units are less powerful than their industrial counterparts, they are much easier to operate.

CNC Milling Machines

CNC milling machines are similar to traditional mills. They consist of two main components: a spindle (which holds the cutting tool) and a bed (where the material is placed).

Unlike other CNC routers, however, CNC milling machines don’t produce finished products. Instead, they create rough cuts that must then be polished by hand.

How Does A CNC Router Work?

A CNC router works by converting digital instructions into physical movements. When you send a command to a CNC router, it translates the commands into movement.

Once the machine has completed its task, it sends the results back to your computer.

How Does A CNC Router Work?

The process begins when you upload a file containing the design specifications for your project onto your router. You can either do this manually or through one of the many software programs that are available.

Once you have uploaded your design, you will need to select the type of material you want to cut. Most CNC routers offer three basic materials: wood, plastic, and metal.

The next step involves selecting the size of the piece you wish to cut out. If you plan to make a chair, for example, you would need to choose between an 8″ x 10″ board and a 2′ x 4′ sheet.

After you have selected the dimensions of your project, you will need to decide whether you want to cut straight lines or curved ones. Curved cuts are often used to create decorative elements such as circles and arcs.

Straight cuts are generally used for creating flat surfaces.

After you have made all of your selections, you will need to specify the location where you want the cut to occur. For instance, if you want to cut a hole in the middle of a board, you would need to enter the coordinates of the center point.

If you are using a manual router, you will now need to input the exact measurements of the area you wish to cut. This information includes the length, width, and depth of the cut.

The depth refers to how deep the cutter should travel along the surface of the material.

Next, you will need to determine what kind of feed rate you want to use. Feed rates refer to the speed at which the cutter moves across the material. There are different types of feeds, including continuous, intermittent, and variable.

Continuous feeds allow the cutter to move continuously from start to finish without pausing. Intermittent feeds require the cutter to stop every so often to change direction.

Variable feeds are similar to intermittent feeds but also include pauses for changing directions.

You will also need to decide whether you wish to turn off the automatic feed system. Automatic feeds enable the cutter to automatically adjust itself based on the thickness of the material being cut.

Turning off the automatic feed allows you to control the amount of pressure applied to the material.

You will also need to set up the tool path. Tool paths are essentially guides that tell the router where to go and how far to travel. Some tools even provide a visual representation of the tool path.

When you are ready to begin cutting, you will need to load the program. Loading the program tells the router to execute the specified tool path.

After loading the program, you will be able to see the progress of the cut on a display screen.

When you are finished with your project, you may need to clean it up. Cleaning up means removing any waste material left over after the cut has been completed.
