In order to improve the efficiency of design and machining of agricultural machine parts and improve the accuracy of machining, it introduced UG simulation design software into the design and machining of five-axis machining center parts. It proposed that it uses Neural Network algorithm to optimize the curve interpolation algorithm, which improves the machining precision by reducing the output error degree. Finally, it carried out the simulation of the machining process. The simulation results show that it successfully realized the modeling and simulation of the machining process by using UG simulation software, and obtained the running track of the cutter. The results shows that the neural network method can effectively improve the machining accuracy by the comparison of the machining accuracy obtained by using and not using neural network algorithm, which is important for agricultural machinery. It has important reference significance for the research on the design and manufacturing method of agricultural machinery.
