Machining process on the parts machining accuracy impact

Machining processThere are roughing and finishing, the impact of which is mainly presented as the intrinsic influence, as well as the impact of force and thermal change. In order to make the machining accuracy to reach the required standard, for these influencing factors, in the processing of parts, we must improve the overall level of the machining process, so that the machining accuracy can be guaranteed, and then improve the quality of the parts.

In parts processing, the staff will implement the corresponding mechanical processing technology, so that not only can make the production of more efficient, but also improve the accuracy of parts processing, on the contrary, if the staff used the processing technology and the actual situation does not match, will make the parts processing accuracy is reduced, in this case, the staff should pay great attention to the machining process, the processing process for the rational use, and thus improve the enterprise's Benefits.

1 Overview of machining processes

The machining process is based on the condition of the mechanical parts, selecting the matching machining process to deal with the parts, so that they meet the specified requirements. From a practical point of view, the machining process significantly affects the machining accuracy, the processor is quite demanding, normally, the processor is required to process the parts effectively in accordance with the relevant principles. First, rough machining, that is, the processing of rough parts, so that the dimensional accuracy of the parts qualified; Second, finishing. In this process, the staff should be precise calculation, according to the size of the parts calculated according to the corresponding data to ensure the accuracy of the parts. Staff in the end of processing, to carry out a comprehensive inspection of the parts, once the parts are found to be outside the scope of the regulations, the parts will be eliminated, and then the implementation of the parts of the packaging process. At the overall level, the processing is an extremely important stage, the need for staff to be strictly supervised, so that not only can improve the quality of production, but also to ensure that the standardisation of the operation of the production staff, which in turn contributed to the overall improvement of the accuracy of parts processing.

2 machining process on the impact of parts machining accuracy

2.1 Intrinsic influences

To parts processing accuracy caused by the greater impact of the intrinsic factors, and the factor is difficult to eliminate, if the geometric accuracy of the machine tool error is relatively large, will bring a serious impact on the subsequent processing, processing of equipment requirements, if the quality of the equipment does not meet the standards, will reduce the accuracy of the parts, but also to make the enterprise suffered a certain loss. Some enterprises, in order to economic benefits, the lack of capital investment in equipment, resulting in relatively backward equipment, unable to meet the requirements of parts accuracy, in the face of this situation, the need for large-scale combination of machinery to be supported, so that not only the parts can be effectively installed, but also to achieve the degree of integration to reduce the impact on the accuracy of the parts. However, in the actual operation, some producers do not standardise the operation, resulting in wear and tear, which makes the machine part of the gap between the existence of a certain degree, reducing the accuracy of parts processing.

2.2 Factors affecting forces

For the processing system, in its operation period, the system will be subject to the role and influence of some external factors, which leads to deformation of the system, ultimately resulting in a greater degree of change in the position of the system, to the normal operation of the system to bring about a significant impact. The reasons for this phenomenon mainly include the following: First, the system has a relatively strong practical ability. In the operation of the system in the process of the stage, when the tool and fixture to use, often require it to have a strong bearing capacity, but once a long time to continue to work, it is easy to make the position of the tool to change, ultimately leading to deformation of the tool. Secondly, the system is composed of various parts, it not only has to bear the pressure brought about by the system, but also to withstand the pressure of the parts, resulting in a relatively large force, resulting in machining accuracy is susceptible to the impact of the force.

2.3 Thermal variables

In the processing stage, the factors affecting the processing accuracy can be divided into situations, first, in the cutting process, some processors for the sake of production efficiency, the lack of the use of professional tools, resulting in low processing accuracy. Second, some processors to make parts up to standard, repeatedly cutting parts, this will generate greater friction, and a certain amount of heat, so not only easy to cause deformation of the parts, but also reduce the quality of the parts. If the parts have a longer length, then you need to give higher requirements for precision conditions, for the machine, there are some parts, in the operation of the time period, these parts will interact with each other, resulting in a continuous rise in the temperature of the machine, when the temperature is in a higher and higher situation, it will result in the machine's own structure suffered, eventually leading to some parts of the tautness, not able to achieve the intended purpose. It is not possible to achieve the intended purpose. The second issue is that, when the machine is heated, it will cause the machine operation to appear a greater degree of change, this situation requires staff to implement cooling measures for the machine, only then can the accuracy of the parts in line with the standard requirements.

3 machining process on the parts machining accuracy control strategy

After the analysis of the many factors affecting the accuracy of parts processing, staff are required to take effective measures to control, first, control the parts manufacturing process. In the application of processing technology, staff need to effectively control the geometric accuracy errors, to prevent greater interference with the accuracy of the parts. Geometric error mainly stems from the use of equipment, the staff did not carry out a comprehensive review of the equipment, resulting in certain safety hazards in the equipment, lowering the quality of production, contributing to the emergence of errors. Second, control the temperature. Staff in the processing period, to effectively control the temperature, once the equipment is found to be running at a high temperature, we must take cooling measures, for example, grinding, mechanical parts will produce greater friction, and the release of greater heat, staff can use water cooling control to achieve the purpose of cooling.

4 Conclusion

It can be seen from the above discussion, the machining process has a greater impact on the parts processing accuracy, so the staff need to effectively control the machining process, to prevent the parts from suffering from the interference of external forces, and then enhance the parts processing accuracy.
