CNC (Computer Numerical Control) Routing is a subtractive manufacturing process that uses computer-controlled equipment to cut and shape various materials, typically wood, plastic, or metal. This process employs a rotating cutting tool called a router to perform complex and high-precision cutting, drilling, and contouring on materials under precise digital instructions.
CNC Routing shares similarities with other CNC processes such as CNC milling and CNC turning, as they all use computer-controlled equipment and follow similar operating procedures. However, there are the following significant differences:
Cutting Tool: CNC Routing primarily uses a rotating routing tool as the main cutting tool; CNC milling typically uses a multi-flute rotating end mill; CNC turning uses a single-flute cutting tool to shape cylindrical parts.
Material Positioning: CNC Routing equipment is usually designed for processing flat or sheet materials (such as plywood and acrylic sheets), which are fixed on the workbench; in contrast, CNC milling and turning processes often handle block or cylindrical workpieces.
Cutting Direction: CNC Routing equipment mainly operates in the X-axis and Y-axis directions, cutting along the material plane; CNC milling and turning equipment can achieve multi-axis movement and complete more complex 3D processing.
Application Scenarios: Although there is some overlap in applications, CNC Routing is often used in large-scale cutting scenarios, such as furniture manufacturing, sign making, and cabinet processing; CNC milling is mostly used for high-precision and complex processing of parts; CNC turning is suitable for the production of cylindrical or rotationally symmetric parts such as shafts and joints.
Despite the above differences, all CNC processes offer the advantages of high precision, strong repeatability, and the ability to process complex shapes without excessive manual intervention. They can improve production efficiency, reduce labor costs, and ensure consistent and high-quality product quality.
Compared with traditional manual engraving or other manufacturing processes such as plasma cutting and laser cutting, CNC Routing has many advantages, as follows:
CNC engraving equipment can achieve extremely high-precision cutting and shaping, meeting fine design and strict tolerance requirements. The computer-controlled nature of this process ensures consistent processing accuracy and avoids error fluctuations that may occur during manual engraving.
CNC engraving equipment can process a variety of materials, including wood, plastic, foam, composite materials, and non-ferrous metals. This versatility makes it suitable for multiple industries and application scenarios such as furniture manufacturing, sign making, prototype development, cabinet processing, and architectural wood mold making.
Through the CNC engraving process, the same design can be accurately and consistently replicated, ensuring the uniformity of multiple parts or multiple batches of products. This feature is of great value in industries with high requirements for precision and consistency, such as aerospace, automotive, and electronics.
CNC engraving technology can process complex shapes and fine patterns that are difficult to achieve with manual processing or require a lot of time. Computer-controlled equipment can easily complete fine cutting, curve processing, and pattern engraving, providing more possibilities for creative design and customized applications.

At EPTAHUB, your design is transformed into CNC routed finished parts through the following steps:
First, use Computer-Aided Design (CAD) software to design the part and save the design file in a vector format. Common vector file formats include DXF, AI, BMP, CDR, DWG, PDF, STL, and SVG are also supported. These formats ensure compatibility with different CNC equipment and software programs, enabling smooth transmission and accurate interpretation of design data.
The second step in converting the design into a physical part is to upload the compatible CAD file to the official website platform through our instant quoting tool. After you confirm the quote, we will proceed to the next steps.
After you confirm the order quote, EPTAHUB will convert the CAD file into G-code. This process is completed using Computer-Aided Manufacturing (CAM) software, which converts the vector file into machine language recognizable by CNC engraving equipment — G-code. Through CAM software, the vector design is converted into a series of precise instructions that guide the CNC engraving equipment to follow the preset tool path and accurately perform cutting, shaping, or engraving operations, ensuring consistency with the original vector design. At EPTAHUB, the processing flow for laser cutting and other CNC equipment is the same as or similar to the CNC engraving flow.
Subsequently, EPTAHUB starts the engraving process and runs the CNC program. The equipment will cut or engrave the material according to the design specifications following the pre-programmed tool path.
After the engraving process is completed, the finished part may require post-processing operations such as sanding, polishing, or surface treatment to achieve the desired final appearance and quality requirements.
In the CNC engraving process, kerf compensation is a crucial step to ensure cutting accuracy. Kerf refers to the width of material removed during the cutting process due to the width of the cutting tool itself. The following are the common kerf compensation methods used by EPTAHUB in CNC engraving:
This method adjusts the tool path by considering the diameter of the cutting tool used. It can be set in the CAM software to offset the tool path inward or outward by half the tool diameter. This compensation method can offset the amount of material removed during the cutting process, ensuring that the final part size meets the design requirements.
Another method is to perform a test cut on the same material to determine the actual kerf width under a specific CNC engraving equipment configuration. Due to factors such as equipment tolerance, component damage, or uncalibrated CNC engraving equipment, runout may occur, resulting in an actual kerf width larger than the theoretical value. By measuring the kerf width after the test cut, the CAM software can be adjusted accordingly to achieve kerf compensation and ensure the accuracy of part sizes in subsequent cutting processes.
In some CNC engraving equipment configurations, preset kerf parameter values are available for specific materials. These parameter values can be stored in the CAM software as a kerf parameter table or preset values, and the tool path is automatically adjusted according to the selected material. There is no need for manual measurement of kerf width or calculation of tool diameter, which simplifies the operation process.
In some cases, kerf compensation can be achieved by modifying the design scheme. By adjusting the size of the vector file to compensate for the expected kerf width, the CNC engraving equipment can cut accurately according to the programming instructions, ensuring that the final size of the part meets the design requirements. This method requires a full understanding of the specific CNC equipment configuration and material properties, as well as careful design adjustments.
