Optimal Adjustment of Weights in Pseudo NURBS-Based Modeling of Servo Stamping Process

Stamping process curve model is made with pseudo NURBS curve.The displacement and velocity demands of stamping process curve are used in the restrains of weights,and then inequalities are established by weights variables to identify the scope of the weights to meet the stamping process requirements.A suitable target function is chosen to work out weights,and using the group of weights an optimized curve which can meet the demands of the displacement and velocity in stamping process will be got.An example is utilized for analysis to get the displacement,velocity,and acceleration curve that meet the process curve demands.
