Many of us may have wondered how these intricate, uniform designs were created in so many woods. These cuts and engravings are not done by hand, but with a machine. CNC is the initials for computer numerical control. This means that the design given to the device is itself converted by the device into a set of numbers to be readable by the device. Only then can CNC read this pre-written plan or program.

During the work, for example during cutting, the fully automatic and programmed CNC goes to specific points and geographical coordinates defined on the design. In fact, for every point on the design, there is a point on three linear axes in the three-dimensional world on the material, and each motion is defined within the framework of these three axes. As a result, a three-dimensional or two-dimensional design is advanced point-by-point by a CNC machine. In this case, there is no need for a machine operator to perform the work, although a supervisor controls the work. This program and design can either be written by one person or designed by a software
The previous form of this device was called NC or numerical control and was made in the 50s of the 20th century. In this way, a motor was designed to move the tool so that the movement of the tool was controlled by the motor force. But soon after, the engine was equipped with digital devices and became the modern-day CNC.
The CNC machine can be applied on various materials such as wood, metal, plastic, ceramic, glass, fabric and composite. Also, different types of this device have been made for different tasks with different elegance and precision. There are different machines for different metallic and non-metallic materials or different types of metals, and this difference is related to how they work and cut. For example, milling cutters, gas cutters, water cutters, plasma cutters, which differ in the type of nozzle; Or 3D printers are examples of CNC cutting machines.
Also, for materials such as wood, for example, types of carpentry, drilling, cutting, engraving and turning are defined, which depending on the amount of delicacy and volume of work, to perform each of these tasks, a type of machine, especially the best choice Is.
Proper CNC machines to wood: Router CNC
One of the common machines for cutting wood is CNC router machines. These types of devices do not require an operator and work automatically. These CNC machines are used for large pieces of wood. These types of CNCs also define the design in three axes for three-dimensional work. Of course, since the number of axes defined for the device is one of the characteristics of the device, there are also router CNCs, which are designed in 4, 5 and 6 axes
Laser CNC
CNC laser cutter or laser cutter are similar in size and configuration to router machines, except that the main cutting work in this machine is done by a powerful laser with a small width. The low width of the laser is the reason for the ability to execute small and delicate designs by this device. Obviously, since the various strength and thickness of each piece of wood, different powers can be adjusted for the CNC wood laser. Cutting wood with the laser CNC delivers a clean output with smooth edges, which makes product payments in later stages quite minor. Another advantage of laser cutting is that it does not produce sawdust when working with wood. For this reason, the health of the people presents at the site and saving energy and money in cleaning the device and the environment after finishing work, can be considered as positive side points of this advantage.
Perforation CNC
For work such as wood drilling, one of the best choices that works best is working with a CNC drilling machine. In this case, a milling machine creates the desired hole or groove, both for the original design and for different ways of connection (such as elite).
Rotary or inlaid CNC
This type of CNC machine is the best tool for heavy wood inlay that performs three-dimensional and complex designs and all kinds of patterns and patterns for wood inlay. These types of inlays are usually used for bases or crowns of tables, furniture and beds, but they are also popular in decorative items.
Consular CNC
Console CNCs are made from a set of powerful processors and controllers to enable tasks such as drilling and inlaying and cutting and cutting at the same time. A variety of tools such as blades, drills, milling machines and other tools are included in this type of 3, 4 or 5 axis machines.
Flat CNC
These types of CNCs work on three main three-dimensional axes and are suitable for inlaying, engraving and turning on a wooden plate or wood product such as MDF.
Advantages of working with wood CNC machine
As it mentioned, the design for a material such as wood is made up of a set of numbers that contain the geographical coordinates of each point. As a result, with this precision of work, and with the narrowness of the cut lines, the delicacy of the output work is remarkable and also makes any kind of design workable. In addition, if the correct operation of the machine is checked, no mistake will be made and no damage will be done to the wood. Also, the power and speed of this work is due to working with the machine is high and a large number of products are produced in a short time. One of the most positive and obvious things about working with a device is that all the outputs are the same shape and uniform, and it is very difficult to find the difference between the outputs. As a result, it is possible to count on the integrity of wood outputs for specific tasks.
Application of wood worked with CNC
Because the CNC machine has a wide range of capabilities and includes a wide range of techniques and tools to provide wood outputs with different appearance and application, these types of wood meet different needs. They do. Furniture and bedding base and crown, construction industry, building facade, space decoration, decorative goods, building doors, cabinets, tables, dishes, lampshades and anything that can be made of wood materials such as wooden accessories and glasses Other examples are the use of wood polished by CNC cutting machines. Letters, typographies, numbers, serial and barcode numbers, geometric designs or Islamic designs, or 3D designs are all types of patterns that can be read and executed by CNC. Due to the fact that each of these woods requires a special technique, CNC machines can handle all of these methods and processes.
