In the process of precise CNC machining, what are the most common causes of the workpiece's resulting deformation?The composition of the material as well as the structure of the workpiece. The degree to which the workpiece deforms is directly proportional to the difficulty of the shape, the aspect ratio, and the thickness of the wall, and it is also proportional to the rigidity and stability of the material. The complexity of the shape, the aspect ratio, and the thickness of the wall all play a role. When you are planning, you should therefore pay attention to minimizing the effect that these factors have on the workpiece. It is especially important for the structure to be reasonable when dealing with large-scale parts. In addition, in order to lessen the amount of workpiece deformation that occurs, it milling parts online is essential to exercise stringent control over the hardness and looseness of the blank.

 

It is very simple for the clamping of the workpiece to result in the workpiece being deformed. It is necessary to select the correct clamping point in order to prevent this deformation, and then select the appropriate clamping force according to the position of the clamping point. Only then will you be able to avoid the deformation. Therefore, you should strive to maintain consistency between the support point and the clamping point of the workpiece. This will ensure that the clamping force is effectively applied to the support, that the clamping point can be brought closer to the processing surface, and that it will be more difficult for the clamping to cause the workpiece to deform.

When there are effects of the clamping force in multiple directions on the workpiece, it is important to take into consideration the order in which the clamping force is applied. It is not easy to make the clamping force too large, so it is important that it is effective in order to bring the workpiece into contact with the support. The primary clamping force, which, in order to counteract the cutting force, should have the effect after it. In addition to finishing the process described above, it is necessary to either make use of the axial clamping force or increase the contact area that exists between the workpiece and the fixture. Increasing the part's rigidity is an effective strategy for dealing with clamping deformation that can occur during the process. When the workpiece is lowered and clamped, increasing the contact area between the workpiece and the custom cnc milling fixture is of great assistance in reducing the amount of deformation that occurs in the workpiece.

 

Workpiece tool cutting accomplished with precision using CNC machining. During the process of cutting, the workpiece will be exposed to the effect of cutting force, which will manifest itself as the phenomenon of yielding the knife. This is an elastic deformation in the direction that the force is acting. It is possible to improve the tool in order to deal with this kind of deformation. During precision machining, the tool must be sharp. This can reduce the resistance between the tool and the workpiece, as well as improve the heat dissipation capacity of the tool when cutting the workpiece, and reduce the residual internal stress on the workpiece.

 

After undergoing precise CNC machining, the material experiences stress deformation. When the component has been processed, the internal stress is brought closer to a balanced state. When some of the materials and heat treatment are removed from the part, the internal stress will change. This will occur even though the shape of the part is relatively stable at the moment. At this point, it is necessary for the workpiece to achieve the balance of force once more. The application of heat to the area in question can be done as a treatment to improve the situation. After the workpieces that need to be straightened have been stacked to a certain height, a specific piece of tooling is used to press them into a straight state, and then both the tooling and the workpiece are placed into the heating furnace together. Based on the data for each individual part, select a unique heating temperature and cooking duration. The internal structure of the workpiece can be maintained after it has been subjected to hot straightening.

In the processing of precision automated parts, what aspects should be paid particular attention to, and why?.

 

Because the domestic machinery industry is expanding at such a rapid rate, the cost of personnel in the field of automated processing is rising at an equally rapid rate. Furthermore, virtually every manufacturer is facing a shortage of talented individuals who possess excellent skills. The rise in the cost of using personnel has resulted in the development of a wide variety of CNC machines, all of which require an increase in their level of intelligence and automation. There are currently many manual machines that CNC Turning Services are being gradually replaced by automated machines. As a result, the requirements that manufacturers have for machines are becoming increasingly stringent. In addition, the production and assembly of automation equipment has become progressively more complicated, which has been followed by a gradual increase in the level of fineness achieved by the parts, which has grown steadily higher. To cut costs as efficiently as possible, you should strive to improve the product's accuracy as much as you can. Efficiency in production is essential, in our opinion, if you want to succeed with automated parts.

 

The accuracy of the initial sketches is ensured to be spot on. The parts are constructed with the drawings as their foundation. In the event that there are issues with the drawings, there is no reason to worry about the follow-up's level of quality and craftsmanship. As a result, there are markings that are both clear and clear, as well as precise drawing dimensions and requirements for the process. Those who are involved in the processing of automated fine parts will appreciate the thoughtfulness of this gift the most. The accuracy of the drawings is important because it will affect the assembly of the equipment in the future. A reliable basis for machining can be established by using accurate drawings. According to the proverb, the drawings are the foundational layer of the automated parts, which is why accuracy is of the utmost significance.

 

The second factor is the experience level of those working in the machining department. It is challenging to establish a stable presence in the field of machining if one does not possess strong skills. Even if it were possible to complete it successfully at a later stage, it would take a significant amount of time to catch up, which would not be justified by the loss, and it would have an impact on the company's delivery. In extreme circumstances, it will even have an effect on the total amount of time it takes to deliver orders to customers, in addition to the planning of fixtures and the planning of processing procedures. Because of this, processing personnel need to have a very professional level of operation in order for automated parts processing to be successful; consequently, professional skills are important. extremely significant.
