Material Removal Optimization Strategy of 3D Block Cutting Based on Geometric Computation Method

During the material removal stage in stone rough processing, milling type has been widely explored, which, however, may cause time and consumption, as well substantial stress for environment. To improve rate waste reuse processing three-dimensional products with a special shape, this paper, circular saw disc cutting is explored to cut convex polyhedron out of blank box, which approaches target product. Unlike optimization, problem cannot be solved by mathematical methods, have geometrical methods instead. An automatic block strategy proposed intuitively considering series optimization first time. obtain big block, constructing planes based on vertices uniquely proposed. Specifically, (the maximum thickness removal) are searched octree algorithm, plane constructed guarantee relatively block. Moreover, minimize time, characteristics intersecting polygon analyzed, accompanied constraints guillotine mode. The algorithm determining path presented feed direction shortest stroke, confirms From suboptimal solution average ratio volume time) generated. Finally, simulation carried box approach bounding sphere both MATLAB Vericut platform. In case study, 85% 19 cuts, achieves five times higher than that one capacity case.
