Under the conditions of parameter optimization for

NC machine tool crossbeam, the technique of shake cycle optimization(SCO) was educed,this method permits weight changing wave, parameter changing by the control of minimizing deformation, and ultimately results in better structure with the weight balanced.Integrated with FEA tool, this optimized technique is very availability and realization facility.This sensitivity-based fast algorithm is credible and feasible in theory by some mathematical models and the practical application tests.
