What is 5 Axis CNC Machining?
5 Axis CNC Machining is an incredibly versatile machining process that implements subtractive machining technology. Through this process, a workpiece is cut into shape using cutting tools working on five axes to deliver a final part.
CNC machining is incredibly popular due to its high accuracy, efficiency, and repeatability. The process starts by utilizing the original Computer-Aided Design (CAD) file to help program cutting tool paths, all managed via Computer Numerical Control (CNC).
Once these tool parts have been programmed into a language that CNC machines understand, the process can be entirely automated, meaning there are minimal manual processes.
Benefits of 5 Axis CNC machining
High-quality finish
Due to the advanced capabilities of a cutting tool working with five axes, a higher quality finish is achievable, as the cutting tools can be shorter on a 5 axis CNC machine. This reduces the vibration of the tool and as a result, reduces the chance of “chatter” marks and ensures a smoother surface finish on the final part. The time-consuming and costly need for hand finishing can be almost entirely eradicated, as 5-axis machines can closely follow contoured geometry that is traditionally harder to machine.
Faster output
Due to the high speed of 5-axis machining and increased automation, there is little need for intervention or manual processes. This is commonly known as “done in one” and “one-hit machining”. The multiple axes mean the whole workpiece can be cut in one go instead of the need for several operations to complete the final piece. This, in turn, results in faster output capacity.
More complex shapes can be produced
5-axis CNC Machining can produce very complex geometries. For example, machining castings and parts that include many different features would, in the past, require a multitude of setups to machine and finish the desired shape. However, with a single set-up, 5-axis machining can complete a piece to its exact requirements with only one fixture in most cases.
