What Manufacturing Process is CNC Machining


CNC machining has become one of the most prevalent methods of manufacturing parts, components, and structures that are precise, intricate, and complex. CNC machining can be used to produce a wide range of objects, from small parts and components to large-scale assemblies. But what exactly is CNC machining, and how does it work? In this comprehensive guide, we will take you through the manufacturing process, from the basics to the technical details.

CNC Machining Basics

CNC machining has a high degree of automation, accuracy, and consistency, which makes it ideal for producing large quantities of identical parts with complex shapes and structures.

What Is CNC Machining?

CNC machining stands for Computer Numerical Control machining, and it is a manufacturing process that uses computerized tools to create precisely machined parts from raw materials such as metal, plastic, and wood. The process involves using a pre-programmed computer interface to control machines that cut, drill, and shape materials into precise shapes and sizes. The machines are programmed using software that controls the specific movements, cuts, and processes needed to create the desired final product.

How Does CNC Machining Work?

CNC machining works by following a set of pre-programmed instructions to control the movement of a cutting tool, known as the CNC controller. The controller operates on the X, Y, and Z axes, moving the cutters and drills along the three primary planes to cut material into precise shapes. CNC machines use machine language, toolpaths, and G-code to direct their movements.

The CNC machining process involves several steps, from design to production, inspection, and finishing. These steps include:

1) Design

The first step in the process is designing the part or the component using Computer-Aided Design (CAD) software and converting it into a format that the CNC machine can read.

2) Programming

Once the design is complete, the programmer creates the tool path, which is the path the cutting tools will take to remove material from the raw materials. The programmer uses Computer-Aided Machining (CAM) software to create the tool path and generate the G-code, which is the language that the CNC machine understands.

3) Setup

The next step is setting up the machine with the right tools and materials. The operator loads the raw materials into the CNC machine, installs the cutting tools, and sets the parameters for the machine’s operation.

4) Machining

With the machine set up and the program loaded, the operator starts the machining process. The machine runs the program, following the tool path and creating the final product with high accuracy, speed, and precision.

5) Inspection

After the machining process is complete, the operator inspects the part or component for any defects, deviations, or errors. This is an essential step to ensure that the final product meets the required specifications and quality standards.

6) Finishing

The last step in the CNC machining process is finishing, which involves post-processing operations such as polishing, deburring, anodizing, or painting the part or component to enhance its appearance, durability, or functionality.

Types of CNC Machining

There are several types of CNC machining processes, including turning, milling, drilling, and grinding. Each process has its unique characteristics and applications, as follows:

CNC Milling

CNC milling involves cutting and shaping materials using a rotating cutting tool. The material is held in place on the bed of the machine, and the cutting tool is guided along the material to create the desired shape.

This process is ideal for creating parts that have intricate shapes, such as engine components, medical equipment, and aerospace parts, among many others.

CNC Turning

CNC turning involves rotating a material against a stationary tool, allowing the tool to remove material from the surface. This process is ideal for creating cylindrical and conical shapes.

CNC turning is commonly used in the production of shafts, screws, nuts, and bolts.

CNC Drilling

CNC drilling involves creating holes in a material. This process is ideal for creating precise holes for fastening parts together.

CNC drilling is commonly used in the production of automotive parts, aerospace components, and medical devices.

CNC Grinding

CNC grinding involves using a rotating abrasive wheel to remove material from a surface. This process is ideal for creating precise, smooth, and flat surfaces on materials.

CNC grinding is commonly used in the production of tools, medical implants, and precision components.


CNC EDM (Electrical Discharge Machining) involves creating a spark between an electrode and a workpiece submerged in dielectric fluid. This creates a spark discharge that erodes the workpiece to create the desired shape.

CNC EDM is commonly used in the production of molds, dies, and press tools.

In conclusion, CNC machining is an essential technology for any company that wants to manufacture products efficiently and with accuracy. The five types of CNC machining we’ve covered here are just a few of the options available, and there are many more.

If you’re interested in outsourcing your CNC machining needs to a professional online CNC parts company or turning parts company, be sure to do your research to find the best fit for your business. Look for a company that offers state-of-the-art technology, quick turnaround times, and a track record of producing high-quality parts.

We hope this article has been informative and helpful in your understanding of the different types of CNC machining.

What Manufacturing Process is CNC Machining

Types of CNC Machines

CNC machines are an essential part of modern manufacturing processes. They provide accuracy, speed, and consistency in the production of different parts. The following are some of the most popular CNC machines:

1.CNC Milling Machine

This machine uses rotary cutters to remove material from a workpiece by moving in different directions. It is ideal for creating intricate shapes and designs and producing complex parts.

2.CNC Lathe

This machine rotates a workpiece against a cutting tool to remove material from the surface. It is suitable for producing cylindrical parts such as bolts, screws, and shafts.

3.CNC Router

This machine uses a spinning cutting tool to remove material from a larger workpiece. It is often used in woodworking to create decorative designs and intricate patterns.

4.CNC Plasma Cutter

This machine uses a high-velocity jet of ionized gas to cut through different materials. It is ideal for cutting metals and producing precision shapes.


Also known as Electrical Discharge Machining. This machine creates an electric spark between the workpiece and tool, which removes the material from the surface. It is ideal for producing complex shapes and parts with high accuracy.

Choosing the right CNC machine depends on various factors such as the type of material, the size of the workpiece, and the complexity of the project. When selecting a CNC machine, it is essential to consider the following:

1.Cost: The price of the machine should be within your budget and offer a good return on investment.

2.Precision: The machine should have high accuracy and produce parts with tight tolerances.

3.Durability: The machine should be made of high-quality materials and have a long lifespan.
