| Summary: | Highlights (1) An automatic generation method of data points of the grinding path is proposed. The data points of the grinding path are automatically obtained by machine vision and digital image processing technology; (2) The evaluation criteria of the robot trajectory planning method are proposed. The root means square is used to compare the two polynomial interpolation methods with the cubic spline function interpolation method. Under the same working conditions, the interpolation method with a higher speed is selected can improve the grinding efficiency; (3) An improved method of particle swarm optimization is proposed. Based on the particle swarm algorithm with random weights, combined with the natural selection algorithm. The time-optimal trajectory optimization model is established, and the improved particle swarm algorithm is used to optimize the grinding trajectory time of the parts to obtain the optimal trajectory. |
