Virtual machining simulation of automatic numerical control machine tool depending on dynamic cutting algorithm

There are many mature numerical control simulation systems on the market at present, but they are basically similar in shape, and only simple geometric simulation is carried out on personal computer (PC), which leads to the lack of realism in the simulation process. In this paper, three-dimensional modelling software is used to model the numerical control machine-tool-workpiece system, and real materials are added to enhance the sense of reality, so as to transform and get the triangular mesh model. Moreover, this paper presents a tool envelope generation algorithm based on mesh model, which can calculate a polygon intersection algorithm based on two-dimensional operation according to the tool trajectory, and determine the spatial position between the tool and the triangular mesh contained in the workpiece. The experimental results show that the algorithm proposed in this paper has low time complexity and meets the basic cutting requirements. At the same time, the virtual machining method of automatic numerical control machine tools based on dynamic cutting algorithm proposed in this paper can effectively improve the machining effect of intelligent numerical control machine tools.
