Main challenges in cnc machine working

What is CNC machining?

የሲኤንሲ ማሽነሪ ክፍልcontrol is a very modern method. It consists of making objects of various shapes using new machining technologies. As its name suggests, this process uses digital controls.

In other words, it is a computer which sends the commands for moving the tools over the initial mass to obtain the desired shape. የሲ.ሲ.ኤን. ማሽነሪ  is a subtractive process in which a part is created by removing material from a starting mass.

It uses machine tools. Such as:

የ CNC የማሽን መለዋወጫ ክፍል ጥቅሞች

 

The main advantage of this process is that it is quick and inexpensive when it comes to manufacturing around ten parts. However, የ CNC የማሽን መለዋወጫ ክፍል has a cost limit when it comes to large-scale production. This is due to the importance of economies of scale.

How has machining changed over time?

It is estimated that the first use of a machining process dates back several centuries before Christ. The first object manufactured by machining, never discovered, is a bowl discovered in Italy.

It was machined in 700 BC. However, it was not until the 18th century, 25 centuries later, that the first attempt to automate machining was made.

The machines, at that time were mechanical and turned with the vapor. It was not until the last century, in the 1940s, that the first programmable machine was developed at MIT.

She encoded የ CNC የማሽን መለዋወጫ ክፍል each movement using punch cards. It was with the proliferation of computers in the 1950s and 1960s that CNC machining was really born and took off.

Nowadays, the process is much more advanced in technology. With Internet, it is now possible to do CNC machining online. Numerically controlled machines are now complex and robotic systems. It has multi-tool and multi-axis capacity.

Role of 3D Printers in CNC Machining Part

የሲኤንሲ ማሽነሪ ክፍልis the control of machine tools using a computer. It has existed since the 70s of the 20th century as an evolution of NC.

It was not necessarily linked to computers. But it was to other means of controlling machine tools. It dates back in the 1940s and 1950s.

For those who consider this type of machining as something very complicated reserved for the industry. Perhaps a machine among the CNC machines developed in small workshops is familiar with 3D printers.

To create CNC Machining Part with a 3D printer, you must follow the steps of the CNC.

1. design the part using software to create a 3D model
2. specifying the movements of the axes
3. The speed of advancement of the tool forming, etc.
4. extract the code of this design
5. and transfer it in a file to the printer control and activate it,
6. Checking that the part is manufactured correctly.

Before NC and CNC Machining Part

The CNC machining and then the CNC made it possible to control the machine tools. It had to occur until then to machine a part.

For example, before CNC and CN machining, the drilling of a tube was carried out by placing the tube.

 

CN machining was an advance in these directions. Because it made it possible to control the machine tool using a strip.

In this way, the intervention of the person at each stage was not necessary. He could accomplish other tasks. Meanwhile, the የሲኤንሲ ማሽነሪ ክፍልproductivity increased enormously.

Before numerical control, the machining processes included an important part of manual manipulation. Currently, some isolated operations are carried out manually, with few parts.

Subsequently, this brought several advantages.

Main advantages of CNC Machining Part

Improved automation in digital control without a computer. This means that the intervention of the person at each stage can be reduced.

Although some manual action always takes place for specific tasks, such as repair and work on prototypes. This increases production at the same time. Since CNC machines can operate 24 hours a day.

Greater precision and consistency of the parts obtained. Current CNC machines have amazing precision and repeatability specifications.

It can easily make two, ten or a thousand identical pieces. It was fundamental in mass production of የ CNC የማሽን መለዋወጫ ክፍል.

Greater flexibility, as machine tools controlled by a computer program new የሲኤንሲ ማሽነሪ ክፍልrequires a little modification. This allows rapid changes to any type of part.

Main challenges of CNC Machining Part

• High operating costs: CNC machines reduce the number of manual workers required in a manufacturing plant. Their use is more expensive. However, the costs associated with operating the machines are gradually decreasing.
• Need for training:initially, the generalization of CNC machining resulted in a lot of unemployment. It reduces the need for manual workers. However, with adequate training, this system generates new specialized job opportunities. As it requires operators of CNC machine tools, programmers, and maintenance personnel. Tools and trainers to teach how it works.

CNC machining operation

Basically, CNC machining allows you to do almost everything that was done manually before.  Place the drill on the axis, activate it, machine it and stop the axis.

Once the machine tool has been digitally configured and put into service, operator intervention is minimal. It is even possible to automate the part loading process.

However, the operator's task is still necessary to perform checks of the measurements and adjustments. So that the የሲኤንሲ ማሽነሪ ክፍልcontinues to function properly.

CNC machine control

The CNC program must be interpreted by the control of the machine tool. It will activate the series of orders in a sequential order.

Step by step, causing the movement of the tool. This check also performs other functions. Such as checking to confirm that the program is working well.

CAM system

CAM is computer assisted machining. There are various software programs that simplify the programming process. In this way, the CNC programmer simply specifies in the software the machining operations to be performed automatically.

Role of metal extraction in የ CNC የማሽን መለዋወጫ ክፍል

Metal extraction industry: is the industry responsible for giving the final form to semi-finished parts. Tube cutting is an example of this type of industry. And the automotive industry is an example of its recipients.

This industry was one of the ones that more manual machines used several decades ago. But today, the CNC versions of these same machines are fully developed.

The most used machine tools in the የሲኤንሲ ማሽነሪ ክፍልindustry are:
