Benefits of five-axis CNC machining

Recently machining center is shifting toward five-axis control. The five-axis machining has high precision and effectiveness.  For instance, the high-end numerical control system with a five-axis linkage can also perform high-precision machining on complex spatial surfaces. Also, it is more suitable for processing modern molds such as automobile parts and aircraft structural components.


Here are a few advantages of 5-axis machining 


1. Machining Of Complicated Parts

One of the essential advantages of 5-axis CNC machining is that complex geometries can be machined very easily. Since the tool-path is continuous, the cutting tool can follow complex trajectories that are not possible to achieve by typical 3-axis CNC machining. 


2. Fewer Settings

In a 3-axis CNC machining process operator sometimes has to break up the process by turning parts for the tool to get access to the hidden areas for machining. So they have to stop the process and do the math for each step of the process. In some conditions, fixtures need to be made for holding the parts in specific angles.


3. Higher Accuracy

Every time the part has to come out of the machine and turned for machining at a certain angle, the home position needs to be reset. Resetting the zero(home) location reduces the positional accuracy of the features of a part in three-dimensional space.


4.  Achieving Better Surface Finishes

By using a 5-axis CNC machining, the cutting tool can reach the areas that are invisible for 3-axis machining easier, while the cutting tool length is shorter. By having the shorter cutting tool, the vibration of the tool reduces, and surface finishes become better.


5.  Cost And Operation Time Reduction

In many cases, 3-axis milling can be more cost-efficient compared to 5-axis machining. However, when CNC operator needs loading and unloading the part multiple times, specifically in higher volumes or batch productions, labor costs become a crucial factor.

Also, if the machining of the part in 3-axis milling requires making fixtures that will increase the value and lead-time of the CNC machined part.


In summary, 5-axis CNC machining can increase the efficiency, accuracy, and reliability of the machining process.
