What is CNC Machining
CNC machining is a type of automated machining process that uses computer numeral control technology to shape an object or a part by removing material from a workpiece until the desired shape is achieved.
CNC stands for Computer Numerical Control. It means utilizing computerized software to control how a machine moves and operates.
It works by converting a digital model of a part into a sequence of computer instructions that control the actions of the machining tools to achieve the desired output
CNC machining equipment works on a variety of parts, such as metals, metal alloys, wood, stone, and more. The size of machine tools can vary based on the specific part that requires manufacturing.
Since it is computer-controlled, CNC machining can deliver superior levels of versatility, efficiency, and precision relative to other common manufacturing methods. This makes it a popular manufacturing choice for a vast range of industries and applications.
Advantages of CNC Machining
Production speed
Production speed is one of the primary reasons which led to the vast and rapid spread of CNC machining. With CNC machining, it is possible to speed up production exponentially since it removes the limitations of human labor.
Consistency
Computer Numerical Control machining ensures that all the parts created look and work the same. There is no possibility of human error. This leads to the fabrication of precision parts that serve their purpose as intended.
Reduction of rejections
In conventional manufacturing processes using manual labor, there was a lot of human error, which resulted in rejections during quality control. This wasted a lot of time and resources. With CNC machining, the whole process is automated, which leads to fewer rejections.
Cost saving
Labor costs include the salary paid to the labor, downtime during breaks, and the added benefits payments.
The accuracy, speed, efficiency, and automation of CNC machining reduce manufacturing costs by minimizing production times and labor hours. These savings can be passed along to customers, creating a competitive advantage and providing an opportunity for business reinvestment.
However, other factors affect CNC machining costs, like quantity, material selection, and geometry.
Material versatility
CNC machining can be performed on practically any material with sufficient hardness.
Manufacturing data tracking
A CNC machine feeds manufacturing data that allows manufacturers to track the entire process for every part. They can learn about the exact machines every part went through during manufacturing. In case of a fault, the exact cause can be tracked immediately.
Accuracy
With CNC machining, it is possible to achieve accuracy on a micro level. Manufacturers can even push that limit with appropriate tools. Such a level of accuracy is not possible with manual operations.
The Four Stages of CNC Machining
CNC machining occurs in four stages:
Before CNC machining begins, the 2D or 3D model of the final design is required. This model is created in CAD software. There are many CAD software programs available online, free and paid.
Creating CAD models is not difficult and can easily be learned. However, some complex parts might require more experience with CAD, for which expert designers can be hired.
No CNC machine understands CAD language directly. CNC machines only recognize movement based on coordinates. Therefore, the CAD model must be converted to a CNC understandable file called G code.
Many CAD software programs can write the output file directly in G code by using the particular setting before saving the file.
In other cases, converting the CAD design to G code will require dedicated software called Computer Aided Manufacturing (CAM). CAM software is a very functional tool when it comes to the automation of machine processes.
Besides using CAM software, many simple free tools can convert simple CAD designs to G code with the click of a button. However, they don’t have the vast suite of features that CAM software offers.
Before starting manufacturing processes, the CNC machine must be set up the right way.
Think of this as configuring the printer before you print something. You need to feed the printer with pages and check specific settings. CNC machines operate similarly.
Before machining begins, there are many setup processes to complete. For instance, you must ensure the workpiece is properly positioned on the machine. The dies must also be set correctly, and other position settings.
Once the configuration stage is complete, the machine operation can begin. For this, you can execute the program on the display panel of the CNC machine.
Depending on what you design, you might have to go through various program prompts to choose different types of settings and options.
Once the CNC program is executed, the machine keeps going till the end of the program. It only stops if switched off by the operator or in the case of an unexpected error or power disruption.
What are the Different Types of CNC Machining Processes?
A CNC machine is not one specific machine, as it is a group of different types of CNC machines working on various machining processes. Some of the most popular CNC machining operations include:
CNC milling
CNC milling is one of the most popular types of CNC machining processes. In fact, many professional machine shops often use a CNC machining and CNC milling process interchangeably. Face milling and peripheral milling are two of the most frequently used CNC mill applications.
In a CNC milling machine, rotating cutting tools move relative to the workpiece to remove material.
The cutting tool (also called a milling tool) is fixed on a spindle that can rotate. The rotation and movement of the spindle give CNC milling machines the ability to perform three or more axes milling operations.
CNC drilling
The CNC drilling process is a lot simpler than using milling tools or the turning process. In CNC drilling, the workpiece is held stationary while a drill bit moves over the workpiece and creates holes.
The purpose of drilling holes might be to add screw bolts, aesthetic requirements, or any other use.
CNC grinding
CNC grinding machines use a rotating flat abrasive wheel for removing material from rough workpiece surfaces. This machine process is usually applied to create a smooth-finished part. The grinding wheel rotates at a very high speed.
CNC routing
CNC routers are very similar to CNC milling machines. The main difference is that in a CNC router, the workpiece is always stationary, and the cutting tool moves in X, Y, and Z dimensions. CNC routers create faster cuts than milling machines without compromising accuracy and design complexity.
What Materials Can Be Processed By CNC Machines?
CNC machining enables working on a wide range of materials. In fact, you do not need various machines for CNC machining materials that are different. Most types of CNC machines support multiple materials allowing them to switch between producing different machine parts with a slight change of tooling.
Metals
Metal is one of the most common materials that undergo the CNC machining process. Its hardness makes using manually controlled machining long, arduous, and less precise. CNC machines provide the best and fastest way to work on metal parts.
Some of the metals that are used to manufacture parts with CNC machines are:
• Aluminum: Aluminum is not just the most abundant metal on earth but also the most commonly used in CNC machining. Its high strength-to-weight ratio makes it ideal for lightweight parts that require decent strength.
• Magnesium: Magnesium is most commonly utilized for creating the outer body of electronics. This is because Magnesium is 33% lighter than Aluminum, making it perfect for reducing the weight of electronics like laptops.
• Titanium: Titanium is one of the toughest materials out there. It undergoes CNC machining for applications in aerospace, the military, and for any other high-grade requirement.
• Cast Iron: CNC machining parts from cast iron is very useful as you can produce parts at twice the speed of producing parts using steel, with less wear resistance on tools.
Alloys
CNC machines can work on metal alloys just as well as metals. Here are the common alloys that go through CNC machining:
• Stainless Steel: Stainless Steel is one of the more popular varieties of steel. Due to its hardness and other physical properties, it is always shaped by the CNC machining process.
• Carbon Steel: Carbon steel is the most widely used alloy in the world. It is cheaper than stainless steel and has higher strength. CNC machines can shape carbon steel with high accuracy.
• Brass: Brass is soft and corrosion-resistant. There are numerous varieties of brass with varying proportions of zinc and copper. All these varieties can be CNC machined.
Plastic
Many people are unaware of it, but CNC machining can also be used to shape plastic parts. Common plastics used in modern manufacturing include:
• Nylon: Nylon is strong, flexible, and fire-resistant. Nylon CNC machined parts are sometimes used to replace some metal parts since Nylon also has good lubrication properties.
• ABS: ABS plastics are often used for applications like injection molding due to their thermoplastic nature. However, for making prototypes, CNC machining ABS is the better way to go.
• PMAA: PMAA Acrylic is strong, transparent plastic. Therefore, PMAA is used for replacing glass in items like optical equipment or food containers.
• PEEK: PEEK is one of the most expensive plastics with exceptional temperature resistance and physical properties. CNC machining of PEEK finds applications in the aerospace and medical industries.
Wood
Wood is another common material used in CNC machining. Not only that, it is actually quite easy to machine due to its soft nature. The most common application is for making furniture.

How Does CNC Machining Compare to Other Machining Methods?
The only practical alternative to CNC machining is machining done by hand. Of course, CNC machining is leaps and bounds ahead of any manual method.
Some of the points to consider about CNC machining vs. manual machining are:
Industries nowadays follow a manufacturing process suitable to meet the large-scale demand. With CNC machining, this demand can be fulfilled effectively. In contrast, manual production methods cannot produce parts at the required rate.
By using CNC machines instead, physical labor can be dedicated to more crucial and intellectual tasks.
CNC machines eliminate the human error factor that is present in manual machining. This leads to better utilization of resources by lowering the number of defective pieces.
There are many tasks that manual machining cannot accomplish due to human physical limitations, such as working on extremely hard materials. CNC machining can complete such tasks with ease.
With CNC machining, there is no downtime due to lunch breaks or shift changes. Additionally, production can run 24/7, which increases productivity by a huge factor.
