Development of 3D Cutting Simulator using Vatti Clipping

In recent years, product shapes have become complicated, and a cutting simulator that can confirm the shape before actual machining is strongly required. In most cases, simulators are developed using a concept called a “voxel.” Voxel representation shapes 3D models, including tools and workpieces, with a set of minute cubes. However, voxel representation has a disadvantage in that it is difficult to accelerate the simulation. Therefore, this study used polygon representation instead of voxel representation. A cutting simulator was developed using the Vatti clipping algorithm from the computer graphics field.
