Computer-aided error modeling of machine tool

Error modeling is the basis of error identification and error compensation of mechanical tools. Traditional error modeling methods are completely done by human. The process is complex and takes long time. The models are difficult to adjust and fit the changeable structure of modern modular machine tools once they have been built. To make error modeling quick and flexible, an automatic error modeling method was proposed based on the MBS(multi-body system) theory and a computer-aided error modeling system was developed. Using this system, the work of error modeling will be done by computer automatically. Users only need to input some information data of the machine tool. The error modeling process takes only about 1 minute. The method provides a good preparation for error automatic analysis and error real-time compensation.
