What methods can improve precision machining accuracy?

2023-06-17

In order to improve the machining accuracy, it is necessary to analyze the original errors that generate machining errors. For the main original errors that generate machining errors according to different situations, corresponding solutions need to be taken. So, what methods can improve the precision of precision machining?

1. Original error compensation method: As most of the original errors are difficult to eliminate, the original error compensation can be processed here. This scheme generates new original errors due to human error, thereby compensating for the inherent original errors in the original process system, reducing processing errors, and improving equipment processing accuracy.

2. By controlling the original error of the numerical control machine tool, the machining accuracy can be improved, the geometric accuracy of the machine tool used for processing components can be improved, and the accuracy of the instruments, tools, and fixtures themselves can be improved. The errors generated by controlling the thermal and stress deformation of the process system can be minimized as much as possible to minimize tool wear, deformation errors caused by internal stress, and measurement errors.

3. The meaning of transfer error is to transfer processing error to a surface that does not affect other processing accuracy. Generally speaking, when processing error occurs on production equipment and thermal deformation error is received, the processing accuracy in the non sensitive direction of the transfer processing error is significantly improved, without affecting equipment accuracy.

At present, the requirements and standards for machining accuracy of Machine element are constantly improving. However, in the processing of some workpieces, there are factors that often affect accuracy. If not properly controlled, the processing quality is difficult to guarantee, which will affect the quality and safety of mechanical equipment.
