Multi-Axis CNC machining is a mission-critical machining technique for modern-day manufacturers.
When compared to traditional CNC machining,this revolutionized technique stands out like no other.It can produce high-volume quality complex parts with utmost precision and accuracy-no wonder this technique finds its utility in a diverse range of industrial applications.
Wondering how it operates?Well,unlike traditional CNC machining that uses only three axes,multi-axis machining contains additional rotational axes as per the need.This unique addition facilitates the creation of intricate features,complex geometries, and curved surfaces that were not-so-easy to achieve before.
Guessing that you are here to have a better understanding of CNC machining- We’ve got you covered.In this blog post,we will help you learn the types of multi-axis CNC machining,their notable benefits,and their common applications in a diverse range of industries. Let’s get started!
Multi-Axis Machining Types
3-Axis CNC Machining
The 3-axis machining operates by utilizing three axes,making it the simplest multi-axis type.
For anyone looking to produce simple geometries with a flat surface,this type of multi-axis CNC machining is ideal.The three axes named X, Y, and Z serve different purposes as highlighted below:
- First is the X-axis – it moves the cutting tool in the right to left direction. This enables the milling head to move along and/or across the length of the workpiece.
- The Y-axis, on the other hand, moves the cutting tool back and forth across the work table perpendicularly.
- The Z-axis, similar to Y-axis, is also perpendicular to the cutting tool. However, in this case, its spindle moves up and down to hit the workpiece.
4-Axis CNC Machining
The 4-axis CNC machining is the next logical upgrade of 3-axis machining.It features 3 standard axes and one rotary axis, which move in different directions on the stationery working table.
The X-axis, for instance, moves from right to left,the Y-axis from top to bottom,and the Z-axis up and down perpendicular to the work table, while the A-axis, which is the rotary ax, rotates the cutting tool along the X-axis. The most notable benefit of using this type of machining is that it produces more angled features than the 3-axis.
5- Axis CNC Machining
The 5-axis CNC machining is the most versatile and popular multiple-axis CNC machining thanks to its ability to provide significant bump power that is mainly needed in many projects. So how does it work? Well, like the 3-axis machining contains the X, Y, and Z axes, the 5-axis includes the same two extra axes, which are A and B.
The A axis rotates on the X axis, while the B axis rotates around the Y axis. The good thing about this type of machining is that it has a short cycle time and can produce complex parts with 3 dimensions. However, it is very expensive and requires a very skilled operator to get the job done right.
7-Axis CNC Machining
It is important to note that the number of axes determines the tool’s and table’s direction in machining.
The 7 Axis CNC Machining contains the linear axes and 4 rotary axes, i.e., A, B, C, and E, which can twist the arm holding the cutting tool. This implies the workpiece can rotate in multiple directions due to the work table pivot. The advantage of this type of multi-axis CNC machining is that it produces metal parts with extreme precision but at a high cost.
Advantages of Multi-Axis Machining
Fast Lead Time and Reduced Overhead
Even though most multi-axis CNC machining have higher upfront costs, they are with the investment. The machines are automated and operate using computer numerical control. This helps reduce the high cost of labor. This means that you don’t need to stress about having many workers, with a skilled practitioner, you should have high-quality metal parts in no time.
Moreover, let’s not forget that these modern CNC machining also have shorter cycles. Thus, you can produce high-volume complex parts at a faster rate. This helps optimize your product’s time to market.
Achieve High-Precision Parts
Since multi-axis machining relies on linear and rotational axes to move the cutting tool, it eliminates the human elements that could cause machining errors, which in turn results in the production of high-precision parts with increased accuracy.
Excellent Surface Finishing
With multi-axis machining, you can forget all about the costly surface finishing option that most manufacturers have to do to increase the metal part’s value and durability. The cutting tools of these modern CNC machines are usually shorter with high maneuverability, allowing better surface finish.
Increased Durability of Tools
Most traditional machines only rely on 3 axes, which calls for more cycles in order for the workpiece material to be cut. Due to continuous usage, these tools wear out often, resulting in low-quality and less accurate parts.
On the flip side, multi-axis CNC machining contains additional rotational axes. They make it easier to pivot the work table for a perfect cutting angle. Plus, the advantage of modern CNC machining is that they can be programmed in a way that ensures the longevity of the cutting tool.
Produce Manufacturing Parts With Complex and Intricate Designs
All manufacturers and engineers can attest that producing complex parts with intricate designs using traditional CNC machining is challenging. As the saying goes, humans are to error. The same adage applies to creating metal parts. Human errors are prone to occur when designing metal parts manually. However, multi-axis CNC machining has solved this problem. With additional rotational axes, it’s feasible to machine complex angles and unique arcs with relative ease.
Common Industrial Applications
Multi-axis CNC machining has benefited countless industries, especially on assembly lines. Let’s have a look at some of the industries that have leveraged this manufacturing technique.
Automotive Industries
Have you ever looked at your car’s engine and wondered what made it? Well, multi-axis CNC is the answer you have been looking for all along. Most engine blocks and gearboxes are always made using this manufacturing technique, thanks to its ability to create high-precision parts that provide consistency for the automotive sector.
Aviation Industries
In order to manufacture complex parts on most airplanes, multi-axis CNC machining is essential. Engineers operating in this thriving industry utilize all types of modern machining technology, ranging from the 3-axis to the 9-axis. This makes it easy for them to produce high-volume complex parts in a short time.
Jewelry Industry
Those earrings, bracelets, watches, rings, or anything else that is considered jewelry containing intricate designs with high-precision parts have a higher possibility of being the final product of multi-axis CNC machining. Most jewelry companies use this technique due to its extreme precision and customization. This means that whatever design you want for any of your jewelry, it’s possible to achieve it with multi-axis.
Medical Industry
If there is one thing that the medical industry has to be cautious about is the precision of medical tools. Here is why- Any miscalculation, including the level of accuracy, can put the patient at risk. This is the primary reason why most surgical tools as well as medical implants are made using this advanced technology.
How to Choose a Multi-Axis CNC Machining
If you are new to the manufacturing industry, the last thing you want is to splurge your money on a certain type of multi-axis CNC machining only to fit your industry’s needs and preferences. Follow these tips to make the right decision!
Determine Your Budget
Every multi-axis CNC machining comes with its own cost depending on tooling, material, and the number of axes. If the machine that suits your industry’s needs is a bit expensive, consider hiring a manufacturing company to get the job done for you.
Determine the Number of Axes
As mentioned earlier, the number of axes affects the complexity and design of the metal parts. If you are looking to design simple parts, the 3-axis machine will serve you well. However, if you are looking to produce high-precision parts with complex designs, you can choose from 5-axis -9-axis machines. If you are unfamiliar with the type of CNC machining, asking for professional advice is integral.
Evaluate the Level of Programming
Multi-axis CNC machines are computer-programmed. The type of software determines the tool paths, coolant flow, the rotation of the tool head, and many other functions. Again, if you are a newbie, you want to consider going for a manageable machine. If not, consider getting a skilled professional to help you through.
