Hysteresis moment precision compensation of spindle system in vertical composite machining machine tool

Abstract To effectively improve the precision compensation and rigidity, according to the structural characteristics of vertical composite machining machine tools, the hysteresis moment precision compensation method was proposed. By optimizing the constrained position, the precision of non-structural geometric changes was effectively compensated. The hysteresis moment precision compensation method proposed in this paper can be well adapted to the micron precision compensation design of machine tools.
