Qu'est-ce qu'une machine CNC 4 axes?
4-L'usinage CNC sur axe est une commande numérique informatique sophistiquée qui étend le mouvement de rotation de l'axe A dans l'usinage à 3 axes conventionnel à l'origine.. Cette machine peut manipuler une pièce sur quatre axes: X, Oui, Z, et un A (ou B) axe pour offrir une polyvalence accrue pour les applications qui impliquent la découpe de formes et de géométries complexes et difficiles à réaliser dans une pièce.
Principe de fonctionnement d'une machine CNC 4 axes
Ici dans une machine CNC 4 axes, l'axe A est généralement l'axe de rotation qui se trouve dans un plan avec l'axe X. Cela signifie qu'avec cette rotation supplémentaire, la pièce peut être usinée sur toutes ses surfaces sans nécessiter l'intervention de l'opérateur. Cette configuration apporte de la précision, fait gagner du temps, et offre également la possibilité de gérer des conceptions plus complexes. Here’s a step-by-step breakdown of the working process:

- Design and Program – The current workpiece was designed using a CAD/CAM system, with an effective or compatible program obtained.
- Machine setup – The workpiece is located on the machine and reference points for the tool are confirmed.
- Machining – The machine can move along the X, Oui, and Z axes, et le 4 axes to machine the part at any angle.
Types of 4-Axis CNC Machining
Here are the different kinds of 4-axis CNC Machines we use:
Continuous Machining 4-Axis
With this, the tool operates on all four axes during the machining process especially when working on hard 3D designs that require consistent contouring. This method is frequently applied in aerospace and power industries especially when working with hard-to-machine materials such as turbine blades and impellers which need multiple inclined cutting edges. Integrated continuous machining further improves surface finish and shortens the machining time because all axes can move in concert without breaks to make a single cross-cutting movement across the desired surface.
Indexing 4-axis Machining
Ici, the workpiece is rotated in small steps on the A-axis and then it remains aligned only at certain angles for machining. This approach is often adopted as the cutter is not required to turn often for multi-sided parts that are non-rotational such as box or prismatic shaped workparts. That is a more efficient solution with high accuracy for basic geometries, which allows it to be applied to molds, logements, and other simple mechanical parts. Some models are machined on one side of the workpiece as the other, to have standardization of the various parts.
Rotary 4-axis Machining
It can turn the workpiece on the A-axis while the cutting tool is unaffected on other axes. This technique is particularly ideal when the shaped parts are round or cylindrical such as shafts, rouleaux, or gears that require a highly finish surface. Rotary machining reduces the time taken to reposition the workpiece and results in evenly distributed cutting on the circumference of cylindrical parts which makes the process efficient for use in cutting symmetrical features on cylindrical workpieces.
Wrap Machining (Cylinder Wrap)
Ici, the cutting tool surrounds the cylindrical contour of the workpiece through the A-axis rotation and can perform sequential engraving or develop any uneven figure on cylinders. It is mostly employed while carving text or other patterns on circular items that include pipes for cigarettes or artistic jewelry.
Simultaneous 4-Axis Machining
Like continuing machining but again more focused on producing types of molds for the complex shapes where controlling each tool past four-axis adjustment is necessary. It is used in machining parts with compound fringes that have very random appearances and require smooth and consistent adjustment of all the axes to acquire certain geometry.
4-Axis High-Speed Machining
This technique is characterized by fast and continuous tool movement and a high cutting speed on all four axes, while operation time is maximized and geometric accuracy is minimized. Its use is best suited for mass production where the highest precision is necessary for successful manufacturing of products, c'est à dire. automobile engines, electronics casing, et bien d'autres.
Contour 4-Axis Machining
Its intended application is to generate intricate forms of contouring on the workpieces. This may be a combination of flat and cylindrical surfaces and employed when a part has some curved as well as straight edges or features thus the cutting tool can adapt to contour change along the A-axis.
4-Axis Twin-Spindle Machining
Some of the latest 4-axe CNC machines are developed with twin-spindle systems in which two spindles work on different parts of the workpiece at a time. This setup enhances efficiency and is preferred under high-production processes because it is possible to work on the various sides or sections at once.

3-Axis vs. 4-Axis CNC Machines: Which Should You Choose?
Encore, the decision about the use of 3-axis or 4-axis CNC depends on the complexity of the workpiece and the application. For simple and flat products, a simple 3-axis CNC may be enough. But for complex shapes that provide multi-faceted geometries then 4-Axis cnc machines are far more accurate and efficient than using time and money.
