2. Definition and Basics of Multiaxis Machining
2.1 Definition
Multiaxis machining can be defined as an advanced manufacturing process that utilizes machine tools capable of simultaneous motion along multiple axes. Traditional machining often involves 3 - axis machining, which operates along the X, Y, and Z axes. These axes represent linear movements in three - dimensional space: the X - axis for horizontal movement, the Y - axis for lateral movement, and the Z - axis for vertical movement. This setup is suitable for a wide range of basic machining operations, such as milling flat surfaces, drilling straight holes, and turning cylindrical parts.
However, multiaxis machining takes it a step further. It allows for the addition of rotational axes, typically labeled as A, B, and C. The A - axis is a rotation around the X - axis, the B - axis is a rotation around the Y - axis, and the C - axis is a rotation around the Z - axis. This additional rotational freedom enables the production of parts with much more complex geometries. For instance, while a 3 - axis machine might struggle to create a part with an intricate curved surface that requires machining from multiple angles, a multiaxis machine can easily handle such a task. It can continuously adjust the orientation of the cutting tool relative to the workpiece, following complex tool paths to achieve the desired shape.
The combination of these linear and rotational axes in multiaxis machining offers a level of flexibility and precision that is unmatched by traditional 3 - axis machining. The ability to move along multiple axes simultaneously allows manufacturers to produce parts with complex geometries in a single setup, reducing production time and improving the accuracy of the final product.

For example, when machining a curved surface, the step - over distance between tool paths can be relatively large, leading to a less smooth finish. The precision is typically in the range of ±0.1 - 0.5 mm. | Allows for high - precision machining of complex parts due to simultaneous movement along multiple axes. It can achieve much smaller step - over distances, resulting in a smoother surface finish. Precision can be as high as ±0.001 - 0.01 mm, which is crucial for industries like aerospace and medical. |
| Production Efficiency | Usually requires multiple setups for complex parts. Each setup adds time for workpiece positioning, tool changes, and calibration. For instance, if a part needs machining on multiple sides, it has to be re - positioned and clamped several times. This leads to longer production times, especially for parts with complex shapes. | Enables multiple operations to be performed in a single setup. By continuously adjusting the tool's orientation, it can complete machining on different surfaces of a complex part without the need for frequent re - positioning. This significantly reduces production time. In some cases, it can reduce the production time by 30 - 50% compared to traditional machining for complex parts. |
| Cost | The initial investment in 3 - axis machines is relatively lower. However, the need for multiple setups, longer production times, and potentially more manual labor can increase the overall production cost in the long run. Additionally, the higher error rate for complex parts may lead to more scrap and rework, further adding to the cost. | The initial cost of multiaxis machines is higher due to their complex design and advanced technology. But in the long term, they can lead to cost savings. The reduction in production time, setup times, and labor costs, as well as the decrease in material waste, can offset the higher initial investment. For example, a study showed that for a medium - sized manufacturing company producing complex parts, using multiaxis machining reduced the overall production cost by 20 - 30% over a period of one year. |
| Complexity of Machining | Suitable mainly for simple parts with basic geometries, such as flat surfaces, simple holes, and regular shapes. It struggles to create parts with complex curves, undercuts, or angled features. | Ideal for producing highly complex parts with intricate geometries. It can handle parts with multiple angles, complex curves, and internal features that are difficult or impossible to machine with traditional methods. For example, it can create a turbine blade with a single setup, while traditional machining would require multiple setups and more complex operations. |
| Tool Life | The fixed orientation of the cutting tool in traditional machining can cause uneven wear on the tool. This is because the tool is constantly cutting at the same angle, leading to higher stress on certain parts of the tool. As a result, the tool may need to be replaced more frequently, increasing tool costs. | The ability to change the cutting angle and tool path in multiaxis machining distributes the cutting forces more evenly across the tool. This reduces the wear and tear on the tool, extending its lifespan. Tools in multiaxis machining can last 2 - 3 times longer than in traditional machining for similar operations. |
