The Basics of 5-Axis CNC Milling
5-axis CNC milling is an advanced machining device that follows the principles of milling. The device consists of a series of rotary cutters that cut against a stationary workpiece – often held in a chunk. However, what makes it superior to other traditional milling devices is its ability to move and deliver cuts along five different axes – X, Y, Z, and two rotational axes (A and B).
This feature allows the machine to perform more dynamic machining, making it suitable for the fabrication of parts with complex designs, geometries, undercuts, and contours. Besides, it performs these with high precision, maintaining the intended dimensional accuracy, which is vital to the aerospace industry.
What is Special About 5-Axis CNC Milling?
This device’s intricacies include its ability to machine a workpiece across multiple axes simultaneously. The synchronized motion enables the cutters to reach angles and points on the material, which would be challenging for traditional milling devices. The 5-axis millers reach these areas without the machinist needing to modify the position of the cutters or switch up the machine setup.
This feature makes this device valuable to industries where high precision and detailing are essential, such as aerospace. While most multi-axis machines can simultaneously cut through three coordinates – X, Y, and Z, the five-axis CNC milling center adds two more coordinates – A and B, for more machining efficacy.
