Abstract:

The technical framework of precision design and assembly error control methods of machine tool linear feed systems was reviewed from three aspects: error transmission mechanism research, precision design and assembly error control. Modeling methods for the relationship between assembly errors and motion errors of machine tool linear feed systems were summarized. The research results of precision design for linear feed systems were summarized, mainly focusing on error weight analysis, precision optimization, and simulation verification. By establishing error traceability chains, the assembly-induced errors can be systematically fed back to the precision design phases for iterative optimization. Moreover, the design parameters were optimized to guide subsequent re-assembly processes, effectively mitigating assembly-induced errors in the machine tool linear feed systems. Finally, the future research directions of assembly error control methods were discussed.

Key words: linear feed system, error transfer mechanism, precision design, assembly error
