  With the development of CNC machine tools toward high speed and high
precision, the traditional static design methods can hardly meet the demand.
Hence, in this paper, the dynamics matching design methods of existing CNC
machine tool feed systems were investigated and analyzed. Further, sub-system
coupling mechanisms and optimization design studies were carried out for each
sub-system. First, the required kinematic indexes must be achieved when
designing the feed system dynamics of high-speed, high-precision CNC machine
tools. Second, the CNC machine tool feed systems generally have four
sub-systems: motion process, control system, motor, and mechanical structure.
The coupling effect between the sub-systems should also be considered in the
design. Based on the dynamics design, each sub-system should be optimized to
maximize the system dynamic performance with minimum resource allocation.
Finally, based on the review, future research directions within the field were
detected.
