What is CNC machining?

CNC (computer numerical control) machining is a process that employs computer-controlled machines to precisely shape and cut all types of materials, ranging from unique polymers to the strongest of metals. This incredibly accurate technology translates computer-aided designs (CAD) into a set of instructions, known as G-Code, that guides the machine on how to move and cut the material with absolute precision.

This tech enhances the efficiency, accuracy, and safety in the manufacturing of submarines and offers numerous benefits:

Ensuring precision

It offers exceptional accuracy, minimizing the risk of human error and ensuring that the submarine components are manufactured to exact specifications ensuring proper fit and functionality.

Producing complex geometries

It can craft intricate and complex geometries, allowing for the creation of submarine structures such as propellers, turbine blades, and more.

Replicating consistently

Once the program is set up, the machines can replicate the same movements and cutting operations accurately, ensuring uniformity and consistent results across multiple production runs.

Prototyping & creating variations

Design changes can be incorporated into the digital program quickly, allowing for the production of updated parts and prototypes without significant delays or retooling.

Providing efficiency

These machines operate automatically, run consistently, and enable high-volume production at reduced time and cost compared to traditional manual methods.

Enhancing quality control

These machines can be equipped with sensors and monitoring systems to detect deviations from desired specifications which help identify any potential safety issues early in the manufacturing process.

Extreme precision for extreme environments

Though giant, a submarine is a highly sensitive vessel that demands impeccably precise components to function optimally. This is where CNC machines play a vital role. 

Imagine this scenario: a Naval submarine is out at sea in the range of an enemy vessel. Thanks to the incredibly precise sonar you helped build using a CNC machine, the submarine crew is able to detect the threat and employ evasive maneuvers to reduce their vulnerability while maintaining real-time updates on the enemy’s position and movements. 

Your career will have a profound impact and contribute significantly to the safety of our Naval crews at sea.


I was in San Diego Harbor on a boat…and this submarine comes right through…I said, I bet I helped build that thing! You know? It was really cool to see.”
