Techniques to Improve CNC Router Operation


When it comes to CNC routers, the heart of it is going to be the tooling, or when the technology finally gets down to the business at hand and starts cutting the wood. When you are considering choosing the appropriate tool for a specific project, you are going to want to take a few different considerations into effect prior to making you decision. Here is what you need to know to improve your CNC router operations.

Shorter Tooling is Always Going to be Better

First off, you are going to want to select a tool that has the shortest length possible, as this is essentially going to guarantee that the tool will be as rigid as it can possibly be. When you are able to maintain this level of rigidity, it is going to ensure that you will be getting the highest performance that you can get.

Always Set Your Shanks True

Next, you are going to want to adhere to the proper collet setting techniques that are going to safeguard you and your tool from any type of damage, potentially shortening its lifespan. Just be sure that you keep in mind that the shank on the machine is going to need to fill out a minimum of 75 percent of whatever the internal diameter of the actual collet may be. If you do this, you will be making sure that no excessive damage will happen to your industrial CNC router.

Always Match Your Tool Diameter to the Materials Being Used

Third, you are going to want to take into account a very important consideration that is easily overlooked when it comes to your tool’s diameter vs. the material’s thickness. When you are going to be in the process of cutting the material you are cutting, it is going to be resisting each and every rotation that your tool is making.

This is what is known as tool deflection. With tool deflection, your tool is going to want to move off the track that it is on, however, the machine is going to want to stay on the linear path that it has already been put on. When you decide to select a tool that has a larger diameter, the entire tool deflection can not only be reduced but in most cases, even prevented altogether. Just keep in mind that this is not always going to be the case and that you may need to assess each individual project depending upon what material is being cut.

Always Choose the Right Rotational Direction

Finally, whenever you are cutting any type of material, you may notice that one side of the project looks much better than the other side of the project does. This is going to be something that is determined by the direction which the tool is rotating. By simply switching the rotation of your tool, you will be able to make the side that isn’t looking as good look just like the good-looking side.
