Abstract: Aiming at the efficiency problem caused by the model intersection operation in tool interference processing algorithm, study on the feature of triangular grid model, building and advance of voxel model, the detection and processing of tool interference were carried out. A dynamically partvoxelization method was developed by generalizing the cuttingplane method and the traditional totalvoxelization method. The data reuse between two adjacent part was achieved.A quick tool interference detection and processing algorithm for triangular grid model based on dynamically partvoxelization model was designed. Experiment was carried out with the stereo lithography(STL) format model was proposed. The research results indicate that the accuracy of huge triangular grid models voxelization is improved through the dynamically partvoxelization method, and the tool interference is found quickly and modified correctly by the algorithm based on dynamically partvoxelization model with high efficiency.

Key words: tool interference; 4axis machining; voxelization; stereo lithography(STL)
