This study is concerned with modeling of excavation process, aiming at optimal planning of motion trajectory as well as optimal design of mechanical structure. In a typical excavating workplace hydraulic excavator is the flagship construction machinery, the efficiency of digging operations by the hydraulic excavator leads to efficiency of the entire workplace. Therefore, the possibility to improve the digging method by the hydraulic excavator is increasing. In the present study, we make a model of the excavation process by the hydraulic excavator. In operation of the hydraulic excavator, the actual hydraulic excavator operator there is the technique for digging empirically efficiently. In this paper, analyze the digging method based on the operator technique, conducted the experiment and the verification by model.
