In precision manufacturing, 5-axis milling has changed the future of machining.
This advanced technology allows manufacturers to machine complex parts with near exact precision, achieving tolerances as tight as +/-0.00001 inches on critical features.
What is 5-Axis Milling?
5-axis milling refers to the use of CNC machines that move along five different axes: three linear axes (X, Y, Z) and two rotational axes (A, B). This enables the machine to approach the part from virtually any direction, offering flexibility for creating intricate geometries. Compared to traditional 3-axis machining, which only moves along X, Y, and Z axes, 5-axis milling reduces the number of steps, which leads to faster production times, more complex designs, and superior surface finishes.
Steps in the 5-Axis Milling Process
5-axis milling includes several important steps. These steps are essential for achieving high accuracy and complexity in manufacturing.
1. Design and CAD Modeling
The first step is creating a detailed Computer-Aided Design (CAD) model of the part. Engineers design the part based on customer specifications, ensuring that it meets the required dimensions, tolerances, and material properties.
CAD modeling is very important in 5-axis milling. This is because the parts often have complex shapes. These shapes need multi-axis movement for machining.
2. CAM Programming
Once the CAD model is ready, it is transferred to a Computer-Aided Manufacturing (CAM) software. This software is responsible for generating the toolpaths that the 5-axis machine will follow during the milling process.
CAM programming demands high sophistication for 5-axis machining. Its main job is to coordinate movements along all five axes. This keeps the tool in the best position at all times. At Apogee, our engineers use advanced CAM software to create efficient and collision-free toolpaths.
3. Setting Up the 5-Axis Machine
Setting up a 5-axis milling machine requires careful calibration. You must align the rotary table and the spindle perfectly to avoid deviations during machining. The operator then loads the machine with the required cutting tools, which may include end mills, drills, and other specialty tools.
Machines like the Doosan DVF-5000 have automated tool changers. These changers can hold up to 120 tools. This feature allows for easy transitions between different machining steps.
- Inspection and Quality Control
After the part is machined, it undergoes inspection and quality control. Apogee uses the Keyence CMM, or Coordinate Measuring Machine. This helps make sure the final product meets the right tolerances and design specifications.
With tolerances as tight as +/-0.0002 inches, the inspection process is critical in verifying the dimensional accuracy and surface finish of the part
- Finishing and Post-Processing
Some parts may need extra finishing processes. These can include polishing, deburring, or heat treatment. These steps help improve strength, appearance, or surface quality. The 5-axis milling process usually gives great surface finishes. However, these extra steps make sure the part meets all customer needs.
Advantages of 5-Axis Milling
1. Reduced Setups and Higher Efficiency
One of the most significant advantages of 5-axis milling is the reduction in the number of setups required to complete a part. Traditional 3-axis machines require frequent reorientation of the workpiece, but 5-axis milling eliminates this need, allowing for faster production cycles and fewer potential errors.
2. Greater Design Flexibility
Complex geometries and intricate designs, such as medical implants or aerospace components, can be machined more efficiently using 5-axis milling. With the ability to machine at various angles without the need for manual intervention, Apogee can produce detailed components that other methods would struggle to achieve.
3. Precision and Tolerances
Precision is critical for industries like medical devices and aerospace, where even the smallest errors can result in failure. Apogee’s 5-axis machines meet the highest standards, offering tolerances as tight as +/-0.0002 inches on critical features. This capability is enhanced by our Keyence CMM system, which ensures that each part is measured and inspected to exact specifications before leaving the facility
4. Improved Surface Finishes
The continuous motion provided by 5-axis milling not only speeds up production but also enhances the surface quality of the machined parts. Since the part doesn’t require clamping and unclamping repeatedly, you significantly reduce surface imperfections caused by misalignment or handling.
