In order to meet the needs of high speed and high quality machining of machine tools, In order to meet the needs of high-speed and high-quality machining of machine tools, this study aims to address the shortcomings of traditional interpolation methods in the processing of complex parts, such as large feedrate fluctuation, the interpolation principle of NURBS curve, interpolation parameter calculation, feedrate fluctuation and other aspects are studied. A NURBS curve interpolation algorithm based on improved Adams method is proposed by combining the speed constraints of machining chord error, machine tool dynamic characteristics, contour error and other constraints. The principle of parameter estimation based on improved Adams method is described, and the principle of interpolation parameter correction based on feed rate fluctuation control is explained. Finally, the simulation on Matlab platform verifies the superiority of the algorithm in interpolation feedrate fluctuation control.
