Computer Numerical Control (commonly known as CNC) machining was first introduced in 1952 by Richard Kegg in collaboration with MIT. Together the first CNC milling machine was developed. CNC machining has since evolved into a magnificent way to take digitized data into a program to control, automate, and monitor a machine’s movements.
There are 6 top myths surrounding CNC machining that you should be aware of if you are interested in these versatile automated machines for your industrial business.

1. No Experience Is Necessary
Most CNC machines are user-friendly, with the latest machining coming equipped with automatic tool pre-setters, high-tech probes, visual programming systems, and many add-ons to make the process easier and simplified. However, this does not mean that your operator doesn’t need to be experienced.
Training will need to be held, and anyone operating the machine will need to learn how to maintain it. The whole process will take time to become familiar with, and the device will only perform to its best ability with a trained operator. It’s also important to note that many things can change and that all CNC-related things are adapting continually.
2. Everything Is Automated
Since the 1950’s there is no doubt that CNC has seen a large variety of advancements, especially when it comes to automation. However, it’s important to remember that it can’t be simply left alone and forgotten about. While it does aim to increase production efficiency as well as overall production capacity, everything will still need to be maintained and taken care of.
Just like all technology, parts need to be replaced, and sometimes problems may arise that impact it’s quality. Remember, even the most robust systems of Swiss CNC machining would not function without skilled operators and programmers. Maybe in the future, we will see even more advancements, but for now, we still need to remember to take things into our own hands.
3. It Is Becoming Too Expensive
While it is true that some older machines were initially expensive, CNC machining, in general, is actually becoming more affordable every year. With new built-in features, operators and programmers can set up parts more efficiently than ever before.
Alongside this, cycle times are being reduced by cutting tools and high-speed machining operations. This is then motivating industrial organizations to carve out space in their budgets to invest in the future-proofing of their manufacturing and factory lines, even when it comes to complex prototyping. While it is uncertain what things will come too, it’s certainly something to take into consideration.
4. Programmers Do Not Need To Know The Ins and Outs of Machines
One myth is that programmers working on CNC machines do not know how they ultimately function. However, it is quite the opposite. These individuals work closely with operators to understand everything involved in the machining process, not just the technical side of it. In fact, many CNC programmers start out as machinists to gather more experience.
This then assists programmers in developing their equipment when they sit down to work in a CNC/CAM environment. When creating a program, there are many factors to account for, which rely on the operator’s knowledge of the machining process and how it all works. At the end of the day, it’s not possible to create without it.
5. CNC Machines Can Make Anything
It’s certainly true that there are many incredible things that can be made using CNC machining. You only have to check out some content online to see it’s possibilities. However, like everything, it does have its limitations. No matter how advanced, it is crucial that you understand what exactly can be created before you think about integrating it into your company.
Make sure you do some research in understanding the capabilities of these machines. It’s critical when coming up with designs as there are just some things that simply cannot be created. Modern CNC machining centers are capable of lots, but these things are dependent on a number of factors that can go beyond the CNC machine itself – such as tooling, materials, and part geometry.
6. You can predict everything
As mentioned above, there are always problems that may arise during the lifespan of a CNC machine. Some individuals believe that you are able to predict production time, and while this is true to a certain extent, it can’t be relied on solely. Delays can always occur, and they aren’t always easy to predict. This means if you are thinking of getting started, you want to be prepared for any mishaps that may happen. Obviously, these won’t be every day, but it’s still better to be one step ahead.
Final Thoughts
By becoming aware of these myths, you can learn more about the entire process and the advantages of CNC machining. No device is going to be perfect, but there are still many benefits that can make it an excellent choice for your company.
