Complex parts are not difficult because they have more surfaces.
They are difficult because every additional setup introduces manufacturing risks:
5-axis CNC machining helps manufacturers overcome these challenges by allowing the cutting tool to approach the workpiece from multiple directions with fewer setups.
The value of 5-axis machining is not simply having more machine axes.
The real value is:
Improved accessibility, reduced setup errors, and more consistent part quality.
Unlike traditional 3-axis machining, which moves the cutting tool along three linear axes, 5-axis machining adds two rotational axes.
This allows the cutting tool and workpiece to move simultaneously, enabling machining from multiple angles in a single setup.
5-axis machining is commonly used for:
One of the biggest challenges in CNC machining is not cutting the material. It is repositioning the part.
Every additional setup creates potential variation:
5-axis machining allows more features to be completed in fewer setups.
Benefits:

In modern multi-axis CNC machining, understanding the distinction between 5-axis machining and 3+2 axis machining is crucial for engineering, manufacturing, and cost-effective production planning.
5-Axis CNC Machining:
5-axis CNC allows the cutting tool or workpiece to move simultaneously along three linear axes (X, Y, Z) and two rotational axes (A, B). This continuous movement enables:
3+2 Axis Machining (Positional Machining):
3+2 axis machining involves rotating the workpiece along two axes and then performing 3-axis linear machining. This is a discrete positioning process: each rotational adjustment requires the tool to complete a 3-axis program before moving to the next orientation.
While effective for simple inclined faces or multi-face components, it cannot perform continuous complex surface machining, and may result in lower efficiency and precision for intricate parts.
| Feature | 5-Axis CNC Machining | 3+2 Axis Machining |
|---|---|---|
| Tool Movement | Continuous simultaneous movement along 5 axes | Discrete movement; rotational axes positioned, then 3-axis cutting |
| Suitable Part Geometry | Complex curves, deep cavities, angled and contoured surfaces | Simple angled surfaces, flat faces, moderate complexity |
| Accuracy | High precision due to minimal repositioning | Moderate precision; requires multiple setups |
| Surface Finish | Superior surface quality | Dependent on multiple setups and orientations |
| Setup Time | Reduced setups due to multi-axis capability | More setups required for multiple orientations |
| Ideal Applications | Aerospace components, medical implants, complex molds, high-precision parts | Inclined holes, chamfers, multi-face panels with less geometric complexity |
Selecting between 5-axis CNC and 3+2 axis machining depends on part complexity, precision requirements, and production efficiency:
Understanding these differences ensures that manufacturers choose the most suitable machining strategy, balancing precision, efficiency, and cost, while leveraging the full capabilities of multi-axis CNC machining.

To achieve the best surface finish on our 5 axis machining parts, a variety of post-processing and surface finishing techniques can be applied.
| Surface Finish | Description |
|---|---|
| Bead blasting | Small glass beads or other abrasive materials are blasted at the surface of the part to remove burrs and create a uniform and matte finish. |
| Black oxide coating | Immerse the part in a hot oxidizing salt bath to create a black protective layer. |
| Passivation | Treat the part with an acid solution to remove any surface iron and create a protective oxide layer. |
| Electropolishing | Remove a thin layer of material to get a smooth and shiny surface. |
| Etching | Remove a thin layer from the surface to create a textured or patterned surface. |
| Anodizing | Create a protective oxide layer on the surface of a part to improve its resistance to corrosion, wear, and scratches. |
The 3, 4, or 5 axis machining is defined related to the number of directions in which the cutting tool can move, this also determines the ability of a CNC machine to move a workpiece and a tool. 3-axis machining centers can move a component in X and Y directions and the tool moves up and down along Z-axis, while on the 5 axis machining center, the tool can move across the X, Y and Z linear axes as well as rotates on the A and B axes, which makes the cutter can approach the workpiece from any direction and any angle. 5 axis machining is different from 5-sided machining. Therefore, 5 axis CNC machining services allow infinite possibilities of the machined parts. Hook surface machining, unusual shape machining, hollow machining, punching, oblique cutting, and more special processes can be done with 5 axis CNC service.
A 5-axis CNC machine utilizes programmed instructions to control the movement of the cutting tool and workpiece, the machining process starts with creating a 3D CAD model of the required parts, then it is exported into CAM software to get a G-code, which guides the operation of the machine. The G-code will contain tool paths that are generated according to the part geometry, the cutting tool will move along linear axes, and the worktable along rotational axes, 5 faces of a workpiece can be made in one setup.
Design and programming: the first step involves designing a part or component using CAD software and then translating it into a CAM program that generates the tool path to be used.
Material preparation: select the right material and make it prepared for machining, including cutting it into a roughly required shape and cleaning it.
Set-up: securely mount the material onto the machine bed or fixture and load the cutting tool into the spindle. The 5-axis machine should be programmed with the tool paths and machining parameters.
Machining: start the machine, and set the spindle rotates at high speeds and the cutting tool moves along the programmed tool path, cutting away material to create the part.
Inspection: when the 5-axis machining is completed, inspect the dimensions, surface finish and other specifications of the part using various instruments.
Based on the movement of the spindle head and worktable, the 5-axis CNC machines can be classified into three major types.
– Head/Head 5-axis machines: the rotational axes are located in the head, this type of 5-axis machine configuration is more suitable for producing large and heavy parts.
– Head/Table 5-axis machines: one rotational axis in the head and another one in the rotary table, the revolving of the axis in the head is restricted and the rotary shaft in the table has a wider range. The rotation of the workpiece has no limit and the number of parts it can manufacture is limited.
– Table/Table 5-axis machines: both the rotary axes are located in the table, and the head does not move. This type of configuration is ideal for producing undercuts and less for large or heavy parts.
In 5-axis CNC machining, there are five axes of motion that the cutting tool can move along. These are typically labeled with letters A, B, C, X, and Y, although the specific labels may vary depending on the machine manufacturer and software used.
– Number of axes: 3-axis CNC machines have movement in three axes (X, Y, and Z), while 5-axis CNC machines can move in five axes (X, Y, Z, A, and B). This additional degree of freedom allows for more complex and precise cuts.
– Flexibility: 5-axis CNC machining offers greater flexibility than 3-axis because they can approach the workpiece from any angle and can machine complex geometries in a single setup. This reduces the need for multiple setups and improves accuracy.
– Efficiency: 5-axis machining centers are usually more efficient than 3-axis machines for machining complex parts. With 5-axis machines, multiple operations can be performed simultaneously, reducing the machining time and increasing productivity.
– Precision: 5-axis CNC service can produce parts with higher precision and accuracy than 3-axis machines. The additional axes of motion allow for more precise control over the cutting tool and the workpiece, resulting in tighter tolerances and smoother surface finishes.
– Cost: 5-axis CNC machining is generally more expensive than 3-axis due to their added capabilities and complexity.
