plug-and-play positioning error compensation model for ripple suppressing in industrial robot polishing
Listed in ScienceDB
Industrial robot-based polisher has wide applications in the field of optical manufacturing due to the advantage of low cost, high degrees of freedom and high dynamic performance.
Description
However, the large positioning error of the industrial robot can lead to surface ripple and seriously restrict the system performance; however, this error can only be inefficiently compensated by measurement before each processing at present.
To address this problem, we discovered the period-phase evolution law of positioning error and established a double sine function compensation model. In the self-developed robotic polishing platform, the results show that the Z-axis error in the whole workspace after compensation can be reduced to ±0.06mm, which reaches the robot repetitive positioning error level; the Spearman correlation coefficients between the measurement and modeling errors are all above 0.88.

In the practical polishing experiments, for both figuring and uniform polishing, the ripple error introduced by positioning error is significantly suppressed by proposed model under different conditions. Besides, the Power Spectral Density (PSD) analysis has shown a significant suppression in the corresponding frequency error. This model gives an efficient plug-and-play compensation mode for robotic polisher, which provides new possibilities for further improving robotic processing accuracy and efficiency.
