Depending upon the particular industry and application, accuracy prevents component failure that could result in expensive downtime, employee injuries, and more. CNC machine tools—including mills, lathes, plasma cutters, electric discharge machines (EDM), and water jet cutters—enable the reliable and consistent production of parts for virtually every industry sector.
CNC machining provides many advantages over traditional machining, including:
Improved worker safety
Reduced labor costs
Higher part accuracy
Visualization eliminates test runs
Higher cutting parameters
Increased tool flexibility
In this blog post, we’ll discuss some ways that various industries use CNC machining.
The aerospace industry is one in which the accuracy and consistency of machined parts are absolutely critical. CNC machines can create complex parts and individual prototypes within the tightest tolerances, which is essential for parts used in aircraft and spacecraft. Examples of commonly machined aerospace components include:
Landing gear parts
Radio frequency suppression materials
CNC machining allows aerospace OEMs and suppliers to meet the strict quality and safety standards held by their industry. Aerospace manufacturers rely heavily on 5-axis machines for superior cutting speed, finishes, and efficiency for many of the smaller components required used in aerospace equipment.

CNC machining is a highly repeatable and accurate manufacturing process for creating parts ranging from prototype to high-volume production runs. CNC tooling uses pre-programmed instructions to cut a solid block of material into the desired part. The versatility of this process makes it suitable for a wide range of applications and their specific requirements. While CNC machining is adaptable, it’s important to start with the right material to achieve the desired finished product.
Material Selection Process
It can be a challenge to figure out which material is the perfect fit for your application. To ensure that your material selection is best for your specific project, it is crucial to follow these steps:
1.Define material requirements. Material selection begins with defining your material requirements. Consider factors such as the electrical and environmental conditions of your application, part size requirements, desired mechanical properties, cosmetic preferences, and cost requirements.
2.Identify top material candidates. Once you have defined your material requirements, narrow down your selection to materials that fulfill those needs.
3.Select the final material. Once you have identified your top material candidates, it’s time to make the final decision. This might mean a compromise between two or more material requirements.
Common Materials Used for CNC Machining
Choosing the material for your CNC machining project can be challenging, so it can be extremely beneficial to consult an expert. Experts can understand your project and its specific requirements and suggest an appropriate material.
Some of the most common materials used in CNC machining include:
Aluminum is a cost-effective, versatile material that is easily machined, making it suitable for a wide range of machining projects. It has a good strength-to-weight ratio, and machining for aluminum parts is quicker than other materials. Although it’s weaker than steel, anodizing aluminum adds a hard, protective layer.
Because of its highly polished look that’s similar to gold, brass is often found in cosmetic applications, such as architecture projects. It’s easy to machine due to its stability and low strength. Brass is also a good choice for low friction applications because of its electrical conductivity.
Considered mild-grade steel, carbon steel is stronger, tougher, and cheaper than stainless steel. It’s easy to machine and weld and is commonly used for industrial applications requiring a high degrees of toughness and strength. Carbon steel can also be heat treated to enhance hardness.
Regarded as the best electrical conductor, copper is perfect for various automotive applications such as cooling and heating exchanges. Copper also features good corrosion resistance, and its thermal conductivity makes it easily shaped during CNC machining.
Nickel is a difficult alloy to a machine, as it produces high levels of heat when cut, and its strength provides resistance to metal removal. However, this material is desirable due to its aqueous corrosion resistance and strength.
Titanium has a high melting point making it ideal for a wide range of industries, including aerospace and medical. This strong but lightweight metal is a good conductor of heat, and its corrosion resistance properties provide protection against salt and water.
Stainless steel comes in many grades and features great corrosion and wear resistance, high strength, and good ductility. This material is easily machined, welded, and polished, and its desirable features make it ideal for the aerospace and automotive industries.

Machining is critical to the manufacturing of products used across multiple facets of daily life. This controlled process involves using power-driven machine tools to cut raw material from a workpiece to produce the desired shape and size from materials such as metal, plastic, rubber, wood, paper, and more.
Machining can be described as conventional, which requires manual technician prompting and manipulation of the cutting tools, or non-conventional, such as CNC machining, which relies on computer automation to drive the process. While each approach offers distinct drawbacks and advantages, both aim to produce the highest quality machined parts.
What is Conventional Machining?
The conventional machining process uses a human operator to direct and control machining tools such as milling, boring, and drilling machines as well as lathes and other sharp cutting tools. This individual is responsible for driving the location and intensity of tool contact with the raw material through the use of buttons, levers, or wheels in order to achieve the intended product geometry.
What is CNC Machining?
Although CNC machining still requires operator oversight to manage software, functions in the CNC process are primarily carried out by pre-programmed computer designations that guide the movements of the machining tools. Tools used in the CNC process do not require contact with the raw materials.
Conventional Machining vs. CNC Machining
While both conventional and CNC machining methods work to create high-quality machined parts, the two differ in many ways.
Conventional Machining. Conventional machining generally costs less and is more cost-effective and efficient for small jobs.
CNC Machining. CNC machining is more expensive for small jobs, but provides greater efficiency and cost savings for larger jobs.
Conventional Machining. The quality of the final product is largely dependent on the skills and abilities of the machine technician or operator.
CNC Machining. Geometry is loaded into the software, so the risk for human error is minimized in the quality equation.
Conventional Machining. Due to human involvement, it is difficult to guarantee a high level of part consistency, making conventional machining ideal for small runs or single pieces.
CNC Machining. Since machines run on computer commands, identical parts or components can be produced with ease, making CNC machining ideal for large quantities of highly consistent products.
Experience and Skills
Conventional Machining. Operator experience greatly influences part quality and consistency.
CNC Machining. Operators with little experience can still produce highly consistent and quality parts due to computer-intervention.
Conventional Machining. Each machine requires a dedicated operator, and a high level of technician involvement is necessary to direct the tools. Operators must be able to produce a variety of parts, which requires extensive knowledge, skills, and experience.
CNC Machining. Since minimal operator involvement is needed to manage the CNC process, a single operator can oversee multiple machines at once with high degrees of accuracy and precision, which reduces labor costs.
Due to improved product quality, highly consistent production replication, and reduced labor demands, CNC machining is the preferred manufacturing method in most instances.
