5-Axis CNC Machining: An Insider’s Guide (Never Forget Again!)

Table of Contents

When it comes to CNC machining, you can expect the utmost precision while achieving the desired shape. And, with the advancement of technology, CNC machining is not limited to just 1 or 3-axis machining. 5-axis machining is the new norm in the manufacturing industry to create parts and components for various actors, from automotive to medical to robotics and aerospace.

Compared to 1-axis CNC machining, 5-axis machining offers a more specific representation, opening a number of doors to machining possibilities. With its additional axes, this cutting tool enables undercutting and access to the parts from all directions. Moreover, it eliminates possible errors and saves time. 

In fact, there are many more interesting facts about 5-axis CNC machining to discover. Let’s begin. 

How Does 5-Axis CNC Machining Work? 

The best part of 5-axis machining is its cutting tool, which can approach a workpiece from five directions, moving across the X (left to right), Y (front to back), and Z (up and down) linear axes while rotating 180° on the A, B, or C axes. 

However, it is easy to set up, with no complex fixtures required to hold the workpiece to be machined. This 5-axis machining program starts with positioning the axis to continue the process, from drilling to tapping to milling. For simple machining parts, it is possible to do it directly on the machine, leveraging the CNC control panel and other programs. For complex machining operations, CAD/CAM systems are used for operating cutting tools, CNC controls, and overall configurations. 

Compared to 3 or 4-axis machining, this machining tool uses shorter and more rigid cutting tools for faster speed and feed, better cutting conditions, and less tool deflection. As a result, the finally machined part offers top-notch surface finishes and better accuracy with heavier cuts, ensuring minimal cycle times for designing parts and components. 

Pros and Cons of 5-Axis CNC Machining in Manufacturing Parts

In the manufacturing industry, 5-axis machining plays a great role in manufacturing parts and components. Although this machining tool has cons, its advantages outweigh them. Such as:

  • Eliminating the preparation time for the machine set up and increasing machining and human efficiency while minimizing machine errors
  • Enabling machines with complex shapes and designs, including injection molds, blood transfusion equipment, gear wheels, and more
  • No manual settings are required, improving machining precision and accuracy.
  • Allowing better surface finish with shorter cutting tools more precisely
  • Easy to eliminate material faster from the workpiece, even the toughest material
  • Saving significant time and costs, expanding product flexibility

Speaking of cons, it requires advanced operator skills to set up and operate its CAD/CAM programming while requiring higher investment compared to 3-axis machining. Still, it is more advantageous in the case of manufacturing complex parts and components. 

Difference Between 3-axis and 5-axis CNC Machining

When it comes to meeting advanced industry news and better support in sectors like aerospace, medical, robotics, defense, and automotive manufacturing areas, 5-axis machining is a better choice as a more powerful and complex machine tool. If compared to 3-axis machining, it is far superior in terms of capability and flexibility, such as:

  • Materials worked and fed on only the X, Y, and Z axes in 3-axis machining, but with the 5-axis, there is a possibility on axes A, B, C, X, Y, and Z.
  • Challenging to create complex parts in one setting with 3-axis but 5-axis machining allows accuracy even with complex machined parts because of its capability of achieving five sides, like 3D shaped parts, tire molds, etc.
  • Simpler programming with a 3-axis machining tool, ensuring faster turnaround time and preparation, while the CAM/CAD systems are used for programming complex part designs

In Conclusion

We hope you have quite a clear idea of 5-axis part machining, including how it works, its setup, pros and cons, and differences with 3-axis machining. It will hopefully allow you to choose this tool for part designs that require precision and unparalleled accuracy.
