Optimization Design and Structure Design of Precision CNC Machine

In this paper, finite element method was used to carry out parameter optimization and structural improvements of CNC machine. Considering the static and dynamic characteristics of the machine, the headstock and bed of CNC machine has been improved by structural optimizationk, and wall ribs was designed on the headstock CNC machine tools. After optimized the static stiffness and strength of CNC machine can meet the requirements, with a decrease of approximately 24.8% in weight compared to the original machine design.
