Decoding of CNC (abbreviations), purpose, operating principle and sequence of control

Decoding of CNC (abbreviations) is literally a numerical program control. In a broader sense, abbreviation means a complex machine control complex with an automatic cutting cycle of parts. To service such systems, highly skilled workers are required.

What does the concept include?

Decoding of the CNC is now known to you. This equipment includes several parts:

• Electric - a control system and automation;
• Mechanical - a pneumatic and hydraulic system;
• External design is a design and convenience in use.

Numerical control gradually eliminates manual methods.

Still there are enterprises in the country where the NC interpretation is required for each employee. However, progress is also moving to the remote places. Machines with software control are introduced into production, even for the simplest operations.

Machines with CNC are profitable in those industries where mass production of the same type of products takes place. These systems are chosen by customers to perform high-precision manipulations with which a person can cope with great difficulty.

The principle of operation of equipment with program control

The CNC decoding includes two parts:

• Numerical control. All operations are based on calculating machine codes. Tracking the state of axes is carried out by removing code pulses.
• Software control includes the conversion of specified commands into a machine-friendly code through applications. The human-machine interface is presented in a visual form.

For one type of parts, the program is only created once and stored on an external medium or in the built-in storage, if memory allows. If necessary, the machine code is transferred to the main memory, and the automatic cycle is restarted. CNC systems are good on any equipment with several coordinate axes.

There is an ideal solution for every production for sale. It is important to take into account all the basic requirements for equipment. Let's enumerate only some of them: the load on the tool, the intensity and speed of processing, the number of axes and the possibility of upgrading the machine in the future.

Furniture manufacturing

Where we are talking about the production of wooden products from MDF boards, a CNC milling machine is suitable. For the consumer, the quality of the product has become important, which can only be achieved by machining with a high number of products. The smoothness and accuracy of the resulting drawings amaze, and the machining at the same time makes furniture more accessible.

The simplest operations were previously created using relay logic. But 3D images are only available to owners of CNC-systems. The processing speed can be twice as high due to the use of two-sided turning, when several technological operations are performed simultaneously. Leaders in the manufacture of controllers that can cope with such tasks are electronics manufacturers:

• "Fanuk";
• "Siemens";
• "Hyndenhain":
• "Aries".

Implement a simple machine is obtained on the basis of a conventional desktop computer. But for the movement of the axes, a control board will still be required. The cost of such solutions is low in comparison with the profit brought by automation of production.

Principle of operation with multi-axis systems

The CNC milling machine must receive a specific command to perform any action. Most control programs are written on so-called G-codes. These are standard simple movements, sewn into the controller memory.

In simple language, to control the machine, the operator selects the direction, the final path, the speed of the tool, and the spindle speed. To produce most of the details, this is enough. But in addition to the commands, it is required to enter the parameters of tool wear, the displacement of the initial processing point, the type of tool, the error of the screw pair.

The sequence of control actions is strictly regulated by machine tool manufacturers. Each manufacturer lays its features in the work of the machine, which will have to be read before performing even the simplest cut.

Sequence of equipment operation

The general principle of operation of machines with numerical program control is the same. Remembering all the steps is easy, and once you have learned how to start the automatic cycle, you can easily manage the rest of the machines. To understand human commands, the machine must read the bit data. To translate into a clear controller type, standard applications for machine tools are used.

The finished model, created according to certain rules, is loaded into the PC and translated into zeros and ones. Further, the received commands are tested on the machine without moving the axes. If everything goes well, debugging begins with the detail. Corrected data depends on the type of material being processed, the complexity of the contours performed, and the state of the tool.
