TPTITLE:Simulation of 5-Axis Machining using Multi-directional Height

TPABSTRACT:Machinists often simulate a part program to verify that it is<nl>correct, since mistakes can cause damage to the part, machine,<nl>yourself, or others.? A popular approach for 3-axis Machining<nl>simulation involves representing the stock (the material the part is<nl>being carved from) as a height map. This approach does not work for<nl>5-axis Machining simulation, since height maps cannot represent<nl>overhangs.? In this talk, I will explain how this limitation can be<nl>removed through use of multi-directional height maps (a kd-tree where<nl>the surface contained in each cell is represented by a height map).<nl>In particular, I will focus on the overhang detection algorithm used.
