Benefits of CNC Machining
Machined parts have become increasingly more complex and intricate over time, and conventional machining is often unable to meet these demands. Fortunately, companies can rely on Computer-Numerical Control (CNC) machining to create cost-effective, high-quality products. Many industries already take advantage of CNC machining from aerospace to automotive to construction.
The objective of CNC machining and conventional machining is the same: transform a raw piece of raw material into a final product. The key difference between these two methods is the level of automation – CNC is highly automated whereas traditional machining relies on manual labor. Before diving into the benefits of CNC machining, it would be helpful to better understand the CNC process.
What is CNC Machining?
CNC machining is a manufacturing process that uses a computer to control machinery. The desired geometry and requirements of the final product are entered into a special software. Then, the software is used to control machinery operating conditions such as speed and location. The computer directs the CNC machine to execute the desired cuts with the machine operating like a robot.
CNC machining is used for metals and plastics, and common operations include lathes, routers, grinders, and mills. Many CNC machines operate on multiple axes to achieve complicated geometries. While most CNC machines operate on the X- and Y- axes at the same time, some advanced machines may have up to five axes that work in parallel, such as ABS’ 5-axis boring mills.

Benefits of CNC Machining
Many industries are turning to CNC machining as a value-add solution for fabrication. Rapid production and product consistency are the advantages of CNC processes that typically come to mind; however, the list of benefits is far more extensive. Below is a summary of the top benefits of CNC machining over conventional machining. It should be noted that each of the factors below contribute to the cost-effectiveness of CNC machining – saving companies time and money and providing a critical competitive advantage.
- Increased Uniformity: CNC machining is known for its accuracy and product quality. The machine executes the same program every single time for a given part. When compared to manual machining, the computer-driven CNC process is more repeatable and less prone to error. CNC templates only need to be designed once and then can be replicated over and over again – hundreds or thousands of times. Additionally, the design is stored digitally so there is no need to manage paper copies of product specifications and templates.
- Higher Production Efficiency: CNC machining is highly automated, resulting in more rapid production and increased efficiency. CNC machines can create a complex part in just minutes. Unlike humans, computers and machines do not need breaks or shift changes, thus, CNC machines can operate 24-7, only needing to stop for routine maintenance or repairs.
- Flexibility: One of the key advantages that is often underestimated is the flexibility and versatility that CNC machining offers manufacturers. CNC processes are able to fabricate geometries that would be impossible with conventional methods. CNC enables opportunities for more complex shapes and sizes of parts. Additionally, the computer program can easily be adjusted as necessary to keep up with customer specifications and requirements over time, making CNC a very nimble solution.
- Less Personnel: The manual nature of conventional machining requires one operator per operating machine. Since CNC machining is driven by the computer, fewer operators are needed to oversee the machining process – all while achieving a higher level of product quality. This reduction in personnel reduces labor costs significantly.
- Improved Safety: One advantage of CNC machining that should not be overlooked is better personnel safety. Conventional machining places operators in direct contact with operating equipment. With CNC machining, however, machine operators are not in close proximity to the machines during operation, and in many cases are even located behind a partition or wall – significantly reducing the risk for injuries.
