5 axis cnc machine for woodworking

What is 5 axis cnc machine for woodworking

CNC machine is also called CNC router, CNC machining center,

CNC milling machine, or CNC carving machine. Usually, 3 axis

CNC machine is the most common. Five-axis CNC machines

move in all three linear axes plus two additional rotary axes. These

CNC routers are able to rotate on two additional axes (compared

to the 3 axis) for cutting three dimensional objects without having

to re-position. A 5 axis CNC machine has the ability to machine

five sides of a cube at one time. 5 axis CNC machine for

woodworing is mainly used to process wood and wood derivatives.

Advantages of 5 axis cnc machine for woodworking

1. Shorter project time

5 axis CNC machine for woodworking has ability to cut five

edges of Wood and derivatives ,so greatly shortening the

processing time.

2. Complex ShapesThe ability to machine complex shapes is the major advantage of 5 axis cnc machine for woodworking.

3. Relational Accuracy

Imprecision finds a way to seep in with every setup change.

Once a part comes out of the machine, precise alignment is

lost. By using the same “zero” or “home” location, feature-to-

feature accuracy is improved.

4. Better Surface Finish

Using the rotating fourth and fifth axes, the part can be

orientated to bring it closer to the cutting tool. If the part can get

closer to the cutting tool, then the cutting tool can be shorter. A

shorter cutting tool is less susceptible to vibration at higher

cutting speeds, which directly impacts surface finish.

Applications of 5 axis cnc machine for woodworking

1. Machining complex 3D shapes

The two rotary axes are utilized to keep the cutting tool

close, and normal to the surface being worked one. In the early

days of five-axis machining, programming a CNC machine for

3D work was almost extremely laborious, and required the

geometry of each work piece to be transferred from the design

to the computer by keyboard, and errors, leading to stalled runs

and possibly to wasted stock, were the order of the day.

Since then CAD/CAM software has improved to the point

where the flow from concept through design to production is

seamless. Far fewer designs originate on paper, and a piece

designed today by an engineer in Finland can be driving a

machine in Perth overnight.

Once a design is imported, the programmer’s job is relatively

simple. However, there are many machining options available,

such as pass rates and cutting path step sizes, to allow for

optimum handling of different workpiece material properties.

2. conventional machining of tilted surfaces

5 axis machines are not always used for 3D work. Their two

rotational axes enable them to machine sloping planes, a frequent

requirement that 3 axis machines cannot meet. They can therefore

be used for many conventional tasks like milling, boring, reaming,

tapping and drilling, where the task axis is not normal to the

machine table. Some training is needed to operate the machine in

this mode, but far less than is required to master its full 3D

capability.

If you need to buy a 5-axis CNC machine for woodworking, having

this information is not enough. For technical information, it’s better

to consult a technical engineer.
