What Kind of Parts Are 5-Axis Suitable for Machining?

Over the past few years, CNC machining technology has evolved from simple machines to more complex ones. 5-axis CNC machining is one of the most advanced machining processes available today. It utilizes subtractive machining techniques that offer endless possibilities for part creation. The technology uses cutting tools that work on 5 axes to cut the workpiece into the desired shape and size.

5-axis machining improves accuracy, efficiency and reliability. The increased number of axes also gives 5-axis milling machines superior performance over comparable machines. In addition, the process allows for complete automation and management using computer numerical control (CNC). As a result, many reliable precision machine shop rely on this technology to provide accurate CNC machining services.

Advantages of 5-axis CNC machining

The ability to move tools and workpieces up to 5 sides simultaneously offers several advantages to many industries. It allows for cost-effective and efficient manufacturing of complex parts.

The following are the key benefits of this manufacturing process:

01. Simple setup operation

A 5-axis CNC machine can machine up to 5 surfaces simultaneously. With traditional 3-axis machining, you may need several setups for parts with multiple surfaces. But 5-axis technology accomplishes the machining of contoured parts and other parts with multiple faces in one structure. This allows you to make parts with complex geometries with fewer setups.

02. Machining complex shapes (GD&T labeling)

The additional rotation in this machining process helps to realize more complex designs and geometries. The machine can seamlessly machine arcs and angles that previously could only be achieved with multiple special fixtures. 5-axis CNC milling process can rotate the part to achieve the desired geometry in a single operation without the need for complex fixturing.

In addition, the technology pairs perfectly with GD&T marking to generate datum features in a single operation. 5-axis precision CNC milling is also suitable for CNC machining applications that require surface profile tolerances on complex contoured surfaces.


03. High Accuracy and Repeatability

The extra setup involved in manual machining compared to CNC machining can cause machinists to lose precise alignment during the manufacturing process. However, the minimal setup involved in 5-axis CNC milling reduces the possibility of errors and improves the accuracy required to achieve superior quality.

Today, different types of 5-axis machines eliminate the need to reposition the workpiece at different angles during machining. As a result, you can be sure of improved machining tolerances. In addition, some machine configurations allow the use of shorter cutting tools. This increases tool life and ensures repeatability.

04. High cutting speeds

5-axis machining ensures that the cutting tool is tangential to the cutting surface. This arrangement allows the tool to remove more material per revolution. As a result, it reduces cycle times and overall machining costs.

05. Smooth surface finish

The additional axes in this technology ensure that the workpiece is correctly oriented closer to the cutting tool. As a result, you can use shorter cutting tools to create the desired shape. These shorter tools can cut at very high speeds with virtually no vibration.

Less vibration further reduces the chance of "chatter" marks on the finished product. The vertical machining process also improves spindle utilization when machining inclined surfaces. As a result, you can use this technology to achieve better surface finishes and reduce the cost and time associated with post-processing.

06. Save cycle time and money

5-axis machining of parts is often done in a single operation because of the high-speed benefits of the process. The single setup involved helps save time and money. In addition, shorter tooling with a longer service life saves money and time by eliminating the need for constant tool changes.

In addition, the 5-axis milling process can be automated, reducing manual operations and labor requirements. This reduces the labor costs involved in the process. Thus, 5-axis CNC machining is a cost-effective solution to accelerate your products to the market.


Disadvantages of 5-axis CNC machining

Despite the many benefits of 5-axis CNC technology, its use is not suitable for certain applications.

Some of the disadvantages of this process include:

01. High initial cost

The cost of purchasing a 5-axis CNC machine and its basic software is high. It is much higher than what is required for a 3-axis machining center. Similarly, the maintenance requirements of the machine are more challenging than that of a conventional machine. This aspect also directly adds to the cost of machining 5-axis parts.

02. Programming Difficulties

The two additional rotary movements and the spatial trajectories of their motion are abstract and complex. For example, to work with free-form surfaces, you need to change coordinates several times; perform complex spatial geometry operations; and consider the coordination of each axis motion.

All of this is necessary to avoid collisions and interference and to ensure the correct amount of interpolated motion. As a result, programming is much more difficult to achieve the required machining accuracy and surface quality.

03. More demands on the operator

5-axis CNC milling is an advanced technology that involves advanced programming, machine setup and operation. As a result, the process requires highly skilled technical operators. This usually means increased labor costs.

04. Fully utilizing 5-axis CNC machining

Underutilization of 5-axis functionality is a common occurrence. Some operators do not understand the full capabilities of the machine. Others may not have the programming knowledge for cutting edge operations.
