| Summary: | Some issues on forming movement modeling when drilling deep holes with the dynamic link generated under cutting are considered. The results of the spindle frequency drift trajectories simulation in Matlab according to the parameters of the servo motor and process characteristics are presented. For the first time, metal drilling cut processes with the ever increasing section modulus determined by chip making are simulated. The phase path describing the forming movement dynamics under drilling deep holes with the increasing section modulus associated with chip making is exemplified. The phase portrait transformation depending on the servo motor parameters and the production process is shown. Recommendations on the motor parameters selection are given. They depend on the processing dynamic characteristics, and on the modulus effect determined by chip making. |
