What are the main advantages of 5-Axis CNC Machining?

Generally speaking, the CNC machining is a very common manufacturing technology applied in rapid manufacturing industry. But 5-Axis CNC machining is special but more important in our manufacturing industry. There are the following advantages.

1. Complex part geometry

5-axis machining allows the tool to move in 5 directions, enabling the machining of complex 3D shapes that are impossible with 3 axis machines.

2. Better surface finish

Since the tool can move in any direction, it can machine surfaces at the optimum angles to achieve the best surface finish and reduce machining marks.

3. Higher material removal rate

Optimized tool engagement and more degrees of freedom allow faster material removal rates compared to 3 axis machining.

4. Less porosity

The ability to machine parts from any angle reduces the incidence of trapped air pockets and porosity that can affect part quality.

5. Less tooling

Since complex parts can be machined in one setup, there is less need for intermediate fixtures and overall tooling compared to multi-setup 3 axis machining.

6. Reduced machining errors  

Fewer setups and fixtures means less chance for errors due to fixture offsets or inaccuracies between setups. This improves dimensional precision.

7. Higher machining flexibility

5-axis machining provides more options to machine complex features in difficult to reach areas, increasing the flexibility of CNC operations.

8. Less hand finishing  

With optimized tool paths and angles, 5-axis machined parts require less hand finishing and polishing after machining to achieve the final dimensions and surface finish.
