CNC Machining FAQ

CNC machining stands for Computer Numerical Control machining, a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. This process allows for highly precise control over complex machinery such as grinders, lathes, mills, and routers, enabling the automated production of intricate parts that meet exact specifications with minimal human intervention.

Unlike manual machining, which requires live operators to prompt and guide the commands of machining tools, CNC machining relies on digital instructions derived from a Computer-Aided Design (CAD) file. After a CAD sketch is developed, a computer converts it into numbers, and those numbers control the machine’s movements.

The benefits of CNC machining include:

High Accuracy and Precision: CNC machines operate with high precision and consistency, making them ideal for producing complex parts with tight tolerances.

Repeatability: Due to its computerized nature, CNC machining can produce numerous parts with exact uniformity, even over long production runs.

Efficiency and Speed: CNC machines can operate 24/7 with minimal downtime, significantly speeding up production compared to manual machining.

Flexibility: Changing the specifications of a part is as simple as updating the CAD file, making CNC machining highly adaptable to design changes.

Production Process: CNC machining is a subtractive manufacturing process where material is removed from a solid block using various cutting tools to achieve the desired shape. It’s well-suited for metal and plastic parts and is known for its precision and ability to produce complex geometries with tight tolerances. In contrast, 3D printing, or additive manufacturing, builds parts layer by layer from 3D model data, which allows for the creation of complex and intricate designs that would be difficult or impossible to achieve with traditional manufacturing methods. 3D printing is versatile in material choice, including plastics, metals, and composites, making it ideal for prototypes, end-use parts, and complex geometries.

Accuracy and Finish: CNC machining typically offers higher precision and better surface finish compared to 3D printing. CNC machined parts have tight tolerances and a smooth surface, often requiring minimal post-processing. On the other hand, 3D printed parts may show layer lines and require additional finishing processes to achieve a smooth surface. The precision of 3D printing has been improving, but it can vary depending on the technology (e.g., FDM, SLA, SLS) and the material used.

Choosing the Right Method: The choice between CNC machining and 3D printing ultimately depends on the specific requirements of the project, including material, precision, surface finish, and cost. CNC machining is the go-to for high precision and larger volumes, whereas 3D printing offers unparalleled flexibility in design and faster turnaround times for prototypes and small batches.
