What is the CNC?

Computer numerical control (CNC) is the system by which an operator can control the machining of a tool. Management is carried out through a control panel and a software program. The orders that are executed from here reach the machine so that it complies with the established guidelines.

The numerical control is therefore responsible for controlling all the movements of the machine. Among them, not only the cut and the precision of it, but also the speed, the type of displacement, etc. In this way, much more precise, exact and personalized results are achieved.

CNC operation

The operation of the computerized numerical control is based on the positioning on the X, Y and Z axes. From these three axes, different automatic machining jobs can be carried out on a piece. The most common are cutting, drilling, milling, threading or roughing. The first task that is carried out is the design of the piece by computer using the CAD program. CAD (Computer Aided Design) software is used to create and modify any design. A drawing technique with which to design the different properties in terms of color, layer, style and material of a piece.

When the final design is ready, the operator goes to the control panel of the machining machine to indicate the necessary orders for the manufacture of the part. The movements that the machine will carry out are integrated into the CNC by means of codes with various specific keys.

The main commands indicated to the tool are those for feedrate, depth, start or stop. However, everything will depend both on the machine that is being used and on the piece and its design that you want to obtain. Tool change, positioning and other movement direction variables can also be included among these commands.

It is for this reason that each machine has its own different CNC program. Lathes and milling machines are the most common machining machines. But, within them, there are a series of types that carry out different jobs with specific pieces. Computer numerical control can be different in all these tools.

Uses and applications of Computer Numerical Control

CNC machining is already used both in large companies and in small workshops, factories and businesses. Precisely, CNC cutting machine is used in joinery and carpentry workshops, for interior design work, industrial design, the textile industry and the manufacture of all kinds of metal parts. Large industrial sectors use CNC machines as essential elements. The aeronautical, aerospace, steel, wind, automotive, etc. sectors. They use machines of this type to manufacture all their parts and components. Turbines, propellers, fuselage elements, parts for cars, ships, trains, etc.

CNC technology is also used in the electrical industry, as well as in all that is dedicated to the manufacture or extraction of metal. Any type of industry today requires the use of computerized numerical control. However, not all companies have the resource. Therefore they can take advantage of CNC services to make the various parts needed. There are many such services and most of them can be found online. Yijin Hardware is one of the few CNC services of good repute. Hiring a CNC service is an alternative for many companies with limited budgets. Instead of buying their CNC machines, it would be cheaper and more practical to hire a complete CNC service. Click here for more like this.
