AI Technical Summary

Problems solved by technology

[0003] 1. Manual grinding of blades has high technical requirements for workers, and its labor load is large. It is difficult to maintain a stable removal of material surplus processing. In addition, manual grinding dust pollution is serious, and it cannot directly reach related technologies in terms of dimensional accuracy and surface quality. Requirements require workers to use samples for repeated comparisons and constant corrections to the polished feel, making it difficult to achieve mass production of high-precision blades;

[0004] 2. It is difficult for industrial robots to achieve high-precision measurement when clamping blades due to their own repeated positioning accuracy limitations, resulting in unstable subsequent correction and grinding quality, which directly affects blade production efficiency

[0005] 3. The blade material removal process is performed on a special CNC grinding machine because the blade needs to be taken off-line to the three-coordinate machine for off-line detection, due to the deformation caused by the clamping stress release, the secondary clamping benchmark is inconsistent, and the secondary programming is to prevent overcutting Many technical problems, such as the conservative process adopted, have led to low processing efficiency of high-precision blades and large fluctuations in mass production quality.

[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
