Frequently Asked Questions About CNC Machining

Q. What makes CNC machining different from traditional machining?

CNC (Computer Numerical Control) machining fundamentally differs from traditional machining in its automation and precision. While traditional machining relies on manual operation by skilled machinists who control tools and movements by hand, CNC machining uses computerised systems to automate the entire process. This shift from human-driven to software-guided operation results in significantly higher accuracy, repeatability, and efficiency.

With CNC, once a design is programmed into the system, the machine can reproduce it consistently across hundreds or thousands of parts with minimal variation. It also allows for the production of highly complex geometries that would be difficult or impossible to achieve manually. Additionally, CNC reduces human error, increases production speed, and enables unattended operation, making it ideal for both prototyping and large-scale manufacturing.

Q. What is the role of G-code in CNC machining?

G-code, short for "Geometric Code," is the standard programming language used to control CNC machines. It provides detailed instructions that dictate every aspect of the machine’s operation, including tool movement paths, cutting speeds, spindle rotation, feed rates, and coolant activation.

Each line of G-code corresponds to a specific command—for example, moving the tool to a precise coordinate (X, Y, Z), drilling a hole at a certain depth, or changing tools automatically. Modern CAD/CAM software often generates G-code automatically from 3D models, but understanding the underlying code allows engineers and operators to fine-tune processes, troubleshoot errors, and optimise machining efficiency.

Because G-code ensures consistent execution of design specifications, it plays a critical role in maintaining quality, precision, and repeatability across production runs.

Q. What does the term “5-axis CNC machining” refer to?

5-axis CNC machining refers to a machining process where the cutting tool can move along five different axes simultaneously: the three linear axes (X, Y, and Z) and two rotational axes (typically A and B, which allow rotation around X and Y, respectively). This multi-directional capability enables the tool to approach the workpiece from virtually any angle.

This advanced configuration is particularly valuable for creating highly complex geometries—such as turbine blades, impellers, aerospace components, and organic-shaped medical devices—without requiring multiple setups or fixtures. By reducing the need to reposition the part, 5-axis machining improves accuracy, reduces cycle time, and enhances surface finish.

It’s especially effective for machining parts with deep cavities, undercuts, or intricate contours that would be difficult or impossible to achieve with 3-axis machines. While more sophisticated and costly, 5-axis CNC is indispensable in high-precision industries where complexity and efficiency are paramount.
