Machine-tool-simulation-model-based motion control performance test system of numerical control device

Abstract

The invention belonging to the field of motion control performance test of a numerical control device discloses a machine-tool-simulation-model-based motion control performance test system of a numerical control device. The system is composed of a simulation module, a data transceiver module, a performance analysis module and a result display module. A simulation model in the simulation module is used for real-time simulation of motion positions and dynamic characteristics of the servo feed shafts of an actual machine tool so as to output the position feedback data of each servo feed shaft. The data transceiver module is used for transmitting the feedback data to the performance analysis module; the performance analysis module is used for data analysis and processing to obtain values of all performance evaluation indicators; and the result display module carries out value outputting and displaying. On the basis of simulation of real machine characteristics and motion characteristics of the machine tool by the simulation model, the corresponding position feedback data are calculated in real time, so that the influence on the motion control performance of the numerical control device by uncertainty of the real machine tool system and inconsistency of the processing performances is eliminated.
