Development of NC Program Simulation Software Based on AutoCAD Swarm Optimization Algorithm

Abstract

In order to solve the three main technical problems in the numerical control machining simulation: the establishment of the blank material model, the interpretation and decoding of the NC code and the three-dimensional dynamic machining simulation, the author puts forward the development of numerical control program simulation software based on AutoCAD. Based on the triangle mesh discrete method, the vertex translation algorithm is proposed to calculate the vertex coordinate value of the triangle, which greatly reduces the complexity of the calculation of the triangle function, and draws the blank based on the powerful embedded 3D graphics interface; Based on the interpretation and decoding of NC code features, the tool drive data information is effectively extracted; In the process of tool cutting, the extended DDA arc interpolation algorithm is improved to improve the cutting accuracy. The experimental results show that: Based on the improved algorithm, the machining simulation is carried out, the 3D effect is lifelike, the radial error of the interpolation point is reduced by about 30%, and the machining simulation accuracy is high. It is proved that the numerical control program simulation software based on AutoCAD can meet the needs of actual production and effectively improve the production efficiency and safety of numerical control stamping.
