An Introduction to 5-axis CNC Machining

photodune qTwzwLcX metalworking cnc lathe milling machine cutting metal modern pro l 1

What is 5-Axis CNC Machining?

In Simple terms, CNC (Computer Numerical Control) machining refers to the process of removing material with high-speed precision machines that make use of a large range of cutting tools. The “5-axis” refers to a machine’s ability to move a tool or a part in five different axes simultaneously. On a 5-axis machining center, the tool moves across the X, Y, and Z linear axes and rotates on the A and C (also say B) axes simultaneously to approach the workpiece from any direction. In other words, you’ll be able to process a part from 5 directions in a very single setup.

What's the Difference Between 5-Axis Machining vs. 3+2 Axis Machining?

5-Axis Machining

5-axis CNC machining offers three linear axes and two rotational axes that job simultaneously to achieve complex surface machining.

3+2 Axis Machining

The 3-axis CNC machining offers a 3-axis milling process, with two additional axes to rotate the holding tool in a fixed position against manipulating it repetitively during the machining process.

Advantages of 5-axis Machining

A 5-axis CNC Machine helps you work on closer tolerances to achieve complex geometries while a 3+2 axis setup allows you to hold less complex parts in positions that allow better access to the features. The Simultaneous 5-axis machining technology raises the bounds on the types of part geometries you’ll machine. By allowing you to produce highly complex components during a single setup, these 5-axis CNC machines unbridle the imaginations of your engineers and redefine your overall capabilities. Equipped with the abilities of machining plenty of materials, to disrupt the manufacturing industries. Some of the benefits of the 5-Axis CNC machine are mentioned below.

Minimized steps

Fewer steps are needed to be made to create complex geometry. It uses a 5-axis technology to create the geometry compared to the traditional machining way. Multiple setups are possible with 3-axis machining but one can minimize the number of steps required to create the final design. It ensures more efficiency and reliability along with higher productivity.

No need for complex fixtures

Often with the 3-axis machine, complex fixtures are required to be made to create orientation and eliminates the requirement of creating the right kind of fixture. The foremost purpose behind this is that the part can be held once and rotated so that the geometry can be created effortlessly. 5-axis machining provides a great ability to make complex shapes in a single setup that leads to saving time, money, and operator error and these are the most predominant reasons behind using this machine.

Fast removal of material

The 5-axis machine allows the cutting tool to remain perpendicular to the cutting surface and therefore allows the cutting easier and faster removal of material. This also lessens the cycle times and the expenses, as well as more material, can be easily removed in every cycle of the tool. One can also check the CNC drilling procedure and it is too pretty much better compared to the other conventional methods.

Better surface finishing

If you are looking for a machine with a better surface finish then this machine is best suited for you. Compared to the traditional 3-axis machine, one can achieve smaller cuts and a good surface finish that results in better lead times and time to market. 

Conclusion

All-in-All The 5-axis machining technology helps in the cost-effective manufacturing of complex designs. Investing in a 5-axis CNC Machine will make an enormous difference to your business’s efficiency, productivity, and most importantly to your bottom line profits.

What’s the Difference: 3,4, and 5-Axis Machining

CNC Machining Services

3, 4, and 5 Axis Machining - Detailed Distinctions

One of the most crucial techniques in CNC precision machining is milling, which has applications in manufacturing mechanical components used in medical sciences, aerospace engineering, manufacturing complex machinery, and more. The milling process involves rotary cutters, which help take out material from a workpiece. Milling is performed by fixing the workpiece at a specific angle to the tool’s axis.

Differences Between 3, 4, and 5-axis Machining

The fundamental difference between 3-axis, 4-axis, and 5-axis machining lies in the movement’s complexity allowed to both the workpiece and the cutting tool, relative to each other. Greater complexity in the motion of the two parts, more complex will be the geometry of the final machined part.

The number of axes on a CNC machine depicts the type of work that it can perform, the level of intricacy achievable in the final part, and the workpiece points that the machine can work upon.

Your preferred choice for a milling machine depends on your exclusive requirements, level of intricacy required, and budget. However, if you run an SME, then consider buying a tabletop CNC mill as it can get the job done with decent results without denting your budget.

Aerospace components demand unparalleled precision, which makes 5-axis machining suitable for the job. However, a 3-axis machine is the one for you if you only need it to dig holes.

Table Top CNC mills

3, 4, and 5 Axis Machining - Detailed Distinctions

3-Axis Machining

The workpiece remains still, and only the cutting tool is allowed to move along the three axes to mill the component. 3-axis machines have extensive applications in machining 2D and 2.5D geometry. 3-axis machining only operates on three axes, which makes the process simple. It enables removing the material in these three axes, described by back to front, side to side, and up and down.

The 3-axis milling fails to design features on an angle to the X-Y-Z coordinate system, irrespective of the feature’s planar quality. This machining process is ideal for manufacturing planar milled profiles, performing drillings, and threaded holes in line with an axis.

Machining a part from all six sides has become possible in 3 axis machining; however, it requires a new fixturing setup for each side. This implementation can get pricey. For a single fixture setup, you can machine only one side of the component.

4-Axis Machining

4-axis milling is similar to the process involved in 3-axis machining, where a cutting tool takes out material from part to create the required shape. This machining process is economical for machining components, which is theoretically attainable even on a 3-axis machine. Unlike 3-axis machining, the -axis the machining process is performed on an additional axis along with the 3-axis of rotation. For a single fixture setup, a user can machine four sides of a component.

A 4-axis CNC machine uses the X, Y, and Z axes, besides another axis of rotation, and is around the X-axis. It is referred to as the A axis. A 4-axis machine does not require fixture change-overs. This benefit provides tighter tolerances which are held between features on various sides of the component.

There are two types of 4-axis CNC machining:

1. Indexing
2. Continous

Indexing in 4-axis CNC machining occurs when the 4th axis undergoes rotation while the machine is not taking out any material. Upon choosing the correct rotation, a brake is applied, and the cutting resumes.

Continuous 4-axis machining is when the machine can take out material simultaneously with A-axis rotation. This feature facilitates the machining of complex arcs, like the profile of cam lobes and helixes.

5-Axis Machining 

5-axis machining traverses all axes of the 4 axis machining besides yet another rotational axis, which helps render unparalleled precision and intricacy in the geometry of components. Such intricately crafted parts are utilized to produce artificial bones, aerospace components, car molds, titanium pieces, architectural, medical, military stocks, and many more.

The 5th axis of rotation occurs around the Y-axis in the X-Y-Z plane and around the B axis. Such multidimensional rotation and part movement deliver unprecedented precision, finish, and work speed during the construction of a component. These precision parts are crucial for high-level implementation, like aerospace and flights.

5-axis machining lets you perform single-step machining, which reduces lead time and promotes the convenience of access to the part geometry. It also strengthens the tool life and process efficiency by tilting the table for precision cutting.

Implementing 3, 4, and 5-Axis Machining 

The 3-axis machine is suitable when you do not require the highest-grade precision in manufacturing but need some degree of quality. It is ideal for –

  • Automatic/interactive operation
  • Milling slots
  • Cutting sharp edges
  • Drilling holes

4-axis machining is a multifunctional and relatively economical process than 3-axis machining and is considered suitable for cases where you require –

  • Intermittent cutting
  •  Engraving on curved surfaces
  •  Continuous cutting

5-axis machining is ideal when you require unprecedented precision and intricacy as the manufactured parts are used in crucial industries like aerospace, medical sciences, and others. It is ideal for:

  • Higher quality finishes
  • Enhancing productivity
  •  Feature accuracy
  •  Machining complicated shapes
  •  Cutting intricacies in components

Conclusion

CNC machining is effective (operation-wise) across several manufacturing-intensive industries as it offers notable advantages, including enhanced product quality control, standardization, and greater precision.

CAD technology is used in CNC machining to automate the process of cutting and shaping. The axes count in a milling machine determines the type of movement attainable by that particular machine.

Importance of 5-Axis Machining

The importance of 5-axis CNC machining in the plastic industry is not much understood because they are rare. They work on 5 out of the 6 axes coordinate systems in the same setup. To put it simply, the machine in one setup — can work on 5 sides of a product part. Only the base will be left out.

The noteworthy part about this is all the 5 axes work together simultaneously. It works to remove material on each surface of the product part other than the base and the clamping area. While the 3 axis machine does the process in multiple setups and manually operated rotations, the 5 axis does it in the same configuration.

CAM software can program the 5 axis machines. The recently manufactured machines are made with better technology and are easy to use. The machine costs more than the other machine but does the work faster, thus breaking even.

Benefits of the 5-Axis Machines

5-axis CNC Machines work with the highest precision with multidimensional rotation to work on all sides of the workpiece. It is preferred to produce components that need intricacy and detailing.

Increases the Life of the Machine

The constant chip load can be regulated, and the cutting position can be optimized to improve its cycle time and life.

Better Surface Finish

The machine head can be lowered and appropriately orient the cutter. That enables work at high cutting speed without pressurizing it. The vibrations are lesser to give the finished product a smoother surface.

Complex Parts Made Sooner

When complex parts are manufactured with less sophisticated machines, they must be cast first. Casting takes months to do. But the 5-axis machine does not require casting, and the products are ready within a few weeks.

Works on Complex Contours Efficiently

The 5-axis machines give a more accurate and smooth surface than any other machine, and it manufactures precise contours. It can even make a perfect sphere. No other machine can produce such accurate contours.

They Provide a Higher Rotational Accuracy

3-axis machines require a change of setup to work on a piece. However carefully it is done, there will be a positional error that brings down its accuracy. But as 5-axis offers better accuracy as it manufactures the part in one setup. It can manufacture many complex shapes with accuracy to fit. Such accuracies are required to maintain tight tolerance.

Conclusion

The CNC machining process cannot be missed while searching for the best manufacturing process for plastic parts. The 5-axis machine requires fewer setup changes that’s why they are fast and effective. The added advantage of a 5-axis machine is that it manufactures parts with more precision and is cheaper.
