Error Compensation Method Error Compensation Method

As an effective system compensation method, the machining error of CNC lathe parts can be controlled within a reasonable range, and the machining accuracy can be improved through error compensation. Through modern technology, high-quality and high-precision parts can be obtained while reducing the machining deviation of CNC lathes. The semi-closed-loop servo system CNC lathe is affected by the reverse deviation, and the repeat positioning accuracy error of the lathe is difficult to be effectively controlled, which affects the accuracy and quality of the machined parts. Based on this, through the error compensation method, the machining error of the part can be controlled within a reasonable range, and the effective compensation of the machining error of the part can be realized. As far as the positioning error of the current CNC lathes is concerned, most of them are kept at about 0.02 mm and do not have the compensation function. With the help of the corresponding hardware and software, the accurate positioning of the tool can be realized, and the existing gap can be eliminated as much as possible.

While not affecting the low-speed one-way positioning of the CNC lathe, it can effectively interpolate the CNC lathe. In this process, for the reverse problem, interpolation processing can be performed on the basis of determining the gap value to meet the needs of parts processing. For other CNC lathes, multiple addresses can be built-in for data storage to realize axis backlash storage and compensation. By changing the movement direction of the lathe axis, the backlash value can be obtained, the coordinate displacement can be effectively compensated, the deviation can be controlled within a reasonable range, the machining accuracy of the workpiece can be improved, and a solid foundation for subsequent machining activities can be laid.

Error prevention

The error prevention method is an effective prevention method. It is not to control errors, but to avoid errors through prevention, or to control them within a reasonable range. Through the optimal design of the machine tool, the possible error problems are comprehensively analyzed, and the error is controlled within a reasonable range as much as possible. For example, improving the machining accuracy of lathe parts according to machining needs, further optimizing the existing lathe structure, and providing support for the machining accuracy and rigidity of subsequent parts. In addition, it can effectively control the processing environment and optimize the processing technology. However, it should be noted that the error prevention method also has certain defects and deficiencies. Excessive improvement of the precision of CNC lathes will not only affect product quality, but also increase processing costs, which is not conducive to the long-term survival and development of enterprises.

Conclusion

In summary, CNC lathes are also affected by various factors such as environment, manufacturing and materials in the production and processing. If the construction deviation of the lathes cannot be effectively controlled, the processing quality of the parts will be affected. Therefore, it is necessary to select a reasonable range, further optimize the existing process, improve the defects and deficiencies in it, and improve the machining accuracy of CNC lathes.
