Considerations To Remember When CNC Cut MDF?


Designers, woodworkers, fabricators, and hobbyists often use CNC-cut MDF for various projects. The main benefit of working with CNC cut MDF is the board's accuracy and consistency.However, there are several factors to consider when using this material.In this blog post, we will go the most important considerations to keep in mind when working with CNC cut MDF. We will also provide suggestion on how to get the most out of your cuts. Read on to learn more!

What Is MDF?

Medium Density Fiberboard (MDF) is a type of engineered wood. It`s made by breaking down softwood or hardwood fibers into smaller pieces and then combining them with a resin binding agent. The result of this wood product that is denser and more uniform than natural wood.

MDF is often used to construct furniture, cabinets, and other woodworking projects. In recent years, MDF has become famous for CNC cutting projects.

MDF makes tiny wood fibers and cuts them into precise shapes and sizes. It makes a ideal for projects that require intricate designs or detailed patterns. MDF can produce clean, smooth, and consistent cuts when cut with a CNC machine.

Any CNC machine uses to cut MDF, but a router is the most commonly used tool. Apart from its smoothness and consistency, MDF produces very little dust.

It also helps to create a cleaner and safer working environment, especially when compared to natural wood. Those who are suffering allergic to dust or have respiratory problems will find working with MDF much easier.

MDF is available in plenty of thicknesses, ranging from 1/8" to 1". The board's thickness will determine the finished product's strength and stability. For example, a thinner board will be less sturdy than a thicker one. Generally, it is best to use wider MDF boards for structural projects and narrower boards for decorative projects.

Considerations Need To Remember When CNC Cut MDF!

MDF is a very versatile material that uses for a wide range of projects. However, a few things to keep in mind when working with it. Here are the most essential considerations to remember when CNC cuts MDF:

Speed And Feeds

The speed and feeds are the two most important factors to consider when cutting MDF. The pace is the rate at which the cutter moves through the material. The feed is the rate at which the material feds into the edge.

The speed and feeds must be carefully chosen to avoid damaging the MDF or the cutter. When in doubt, it`s always best to err on the side of caution and go slow. It is better to take more time to cut the MDF than to damage the material or the cutter. 

Below are the recommended speed and feeds for cutting MDF:


An endmill is a one type of milling cutter that use to cut and shape a variety of materials. Endmills are available in various sizes, shapes, and styles. The most common endmills make from high-speed steel or carbide.

These materials offer a good balance of strength and durability. On the other hand, endmills made from titanium or cobalt is also available. These materials are more expensive, but they offer better performance.

Let's Take A Closer Look At The Different Types Of Endmills:

  1. High-speed steel (HSS) endmills are the most common type of endmills. They are made from high-carbon steel that is hardened and tempered. HSS end mills are designed for general-purpose machining.
  2. Carbide endmills are made from a carbide material that is harder than HSS. Carbide endmills offer better performance, but they are more expensive.
  3. On the other hand, titanium endmills make from titanium alloy. Titanium endmills can offer better performance than HSS or carbide endmills. However, they are also more expensive.
  4. Cobalt endmills have a higher percentage of cobalt in the alloy. It makes them even more challenging and more vital than titanium endmills. These endmills offer maximum performance but are not recommended for general-purpose machining.

Cooling & Lubrication

Cooling and lubrication are two essential factors to consider when cutting MDF. The goal is to keep the cutter cool, and the MDF lubricated. It will helps to prevent damage to the material and the edge.

There Are A Few Different Ways To Cool And Lubricate The Blade:

  1. Air cooling is the most common method of cooling. Air coolant is directed at the edge to keep it cool.
  2. Liquid cooling is another option. A liquid coolant uses to cool the cutter. This method is more effective than air cooling but is also more expensive.
  3. Lubrication is used to reduce friction and heat. Various lubricants, including water, oil, and cutting fluids, can be used.
  4. Cutting fluids are the most effective lubricants. They are designed to decrease friction and heat. However, they can be expensive and cause health problems if inhaled.


We have listed some of the most important considerations when working with MDF. To follow these tips, you can avoid damaging the material or the cutter. CNC Cut MDF can be a great way to create unique shapes and designs.
