In the process of precision mechanical parts processing, in order to complete the contour of the machined part surface, we need to use approximate forming operation or blade contour to finish.
In the process of processing close components, there will inevitably be errors, which are called machining principle errors. Theoretically, in order to reduce the surface roughness
To achieve the accurate surface of the parts to be machined, the ideal machining principle and accurate forming movement are required. In the actual processing of precision machine tools,
Precise machining principle is difficult to achieve, and there will still be some gap between it and the ideal value. If we only pursue accurate theory, it will often affect the precision machine
The efficiency of machinery processing enterprises can not achieve the expected results.
In the process of precision machining, the complex structure between the machine tool and processing tools will also increase the difficulty of processing, including too complex structural rings
Therefore, it will increase the error during the operation of the machine tool, and it is difficult to ensure the precision of precision mechanical parts
The key problem is how to use the approximate principle more reasonably to increase the machining accuracy of parts, so as to ensure the accuracy in the machining process, and to ensure the zero
The quality of components, at the same time, through the adoption of scientific and reasonable technological measures, can effectively improve the productivity of precision mechanical parts processing, thus improving the enterprise's economic
Economic benefits.
How much does the principle of machining process affect the machining accuracy of precision mechanical parts?
Numerical control technology will also affect the accuracy of parts. Nowadays, the use of numerical control machine tools is more and more popular, because numerical control machine tools use high and new computer technology
Control the whole precision machining technology, saving a lot of manpower. In addition, numerical control technology can also use precision instruments that cannot be used by human beings to control raw materials
Processing can not only improve the accuracy of parts, but also improve work efficiency, although CNC technology can eliminate or reduce many errors caused by human factors
Poor, but the NC process itself also has its weakness of generating errors. Such as the selection of programming origin, processing route, interpolation operation, trajectory fitting, etc.
In a word, in the process of the development of the machinery manufacturing industry, people pay more and more attention to the quality of precision machining process, so it is necessary to adopt relevant
The processing accuracy of precision mechanical parts has been further improved with the continuous development of science and technology,
People also apply many advanced science and technology to it, which makes it possible for people to obtain qualified quality and high precision in the process of machining and production of mechanical parts
