Typical structure parts library design and research on Machine tool fixture

Based on the Group Technology, Family part technology is adopted for standard part design, as well as parametric driven technology is adopted for non-standard part design, combined with assemble knowledge description and associated driven technology, typical structure parts library is realized by parametric driven assemble parts. For typical structure parts library in machine tool fixture, firstly, multi-classification and key words index is designed for management; secondly, several format files are managed in mapped directory by keywords and meta-data is generated by content description of those files based on analysis constitute of design information; Thirdly, process of making use of library is designed for top-down functional design. Typical structure parts library can maximize reuse the knowledge and parts of fixture design, greatly promote design efficiency.
