5-axis machining capabilities in Fusion allows for precise and efficient production of complex geometries, optimizing manufacturing by reducing cycle times and improving material usage.
5-axis machining is a manufacturing process that uses computer numerical control (CNC) to move a cutting tool or part along five different axes at the same time. In addition to the standard three linear axes — X, Y, and Z — it includes two rotational axes that allow the tool to tilt and rotate. This means that the tool can approach the part from virtually any direction. This makes it possible to machine complex shapes, deep cavities, and intricate features in a single setup. As a result, 5-axis machining reduces the number of setups required, shortens machining time, improves surface finishes, and increases part accuracy. It is especially useful in industries where precision and efficiency are critical, such as aerospace, automotive, and medical device manufacturing.
5-axis machining offers significant advantages over traditional 3-axis methods by providing greater flexibility, precision, and efficiency. It allows the cutting tool to reach multiple sides of a part without the need to reposition it manually, which reduces the number of setups and the potential for human error. This leads to faster production times and more consistent results.
The ability to use shorter, more rigid cutting tools also improves surface quality and extends tool life. For complex geometries, undercuts, and parts with tight tolerances, 5-axis machining makes it possible to achieve results that would be difficult or impossible with other methods. It also helps manufacturers stay competitive by enabling them to take on more challenging projects, reduce costs associated with fixtures and rework, and deliver high-quality parts with speed and accuracy.

5-axis machining moves the cutting tool or the workpiece simultaneously along five different axes—typically X, Y, Z (linear axes) plus two rotational axes (A and B). This allows the tool to approach the part from almost any direction, enabling the machining of highly complex geometries in a single setup.
In contrast, 3-axis machining moves the tool or part only along the X, Y, and Z axes, which limits the tool approach angle and often requires multiple setups to machine complex parts.
Improved accuracy: Fewer setups reduce errors caused by repositioning.
Shorter cycle times: Complex parts can be machined in one go, speeding production.
Better surface finish: The tool maintains optimal angles, reducing the need for manual polishing.
Ability to machine complex parts: Intricate shapes and undercuts that are impossible with 3-axis become feasible.
Longer tool life: Using shorter, more rigid tools reduces vibration and wear.
5-axis machining is ideal for parts with complex curves, multiple angled surfaces, or intricate details, such as:
Aerospace components like turbine blades and structural parts
Automotive molds and prototypes

A: In 5-axis machining, the machine operates along five different axes simultaneously, which allows for more complex and precise shaping of parts compared to traditional 3-axis machining. Here’s how each axis works and why they’re important:
X, Y, and Z Axes: These are the primary linear axes and are common to most CNC machines.
Together, these three axes allow movement in a 3-dimensional plane. However, with only X, Y, and Z axes, the machine has limited access to the part’s surfaces, requiring multiple setups to complete complex shapes.
A and C Axes (Rotary Axes): The additional two axes in 5-axis machining provide rotational movement, allowing the cutting tool to approach the part from various angles without repositioning.
In some machines, the additional rotational axis is referred to as the B-axis rather than the A-axis, depending on the specific configuration. The combination of linear and rotary axes in 5-axis machining provides maximum flexibility, enabling complex, multi-sided machining in a single setup. This reduces setup time, enhances accuracy, and allows for intricate part geometries, which are especially valuable in industries like aerospace, automotive, and medical device manufacturing.
By utilizing these five axes, manufacturers can achieve greater precision and efficiency, delivering high-quality parts with complex shapes and tight tolerances.
