文摘

Simulation of power flow in machine tools is crucial for future development of energy efficient machines as well as for energy optimization of existing machines, production systems and manufacturing processes. This paper describes analytical approach for modelling of energy consumption of auxiliary units of the CNC machine with corresponding activity management, because these units are usually not included in current models. The developed model is then compared with the measurement of the real 3-axis machine to prove the accuracy of the model. Results show the need to calibrate the real consumption of each unit instead of theoretical value from the plate of the unit. Without this calibration, models can be inaccurate.
