Marshall Hahn	Title : Simulation of 5-Axis Machining using Multi-directional Height maps Abstract: Machinists often simulate a part program to verify that is correct, since mistakes can cause damage to the part, machine, yourself, or others. A popular approach for 3-axis Machining simulation involves representing the stock (the material the part is being carved from) as a height map. This approach does not work for 5-axis Machining simulation, since height maps cannot represent overhangs. In this talk, I will explain how this limitation can be removed through use of multi-directional height maps (a kd-tree where the surface contained in each cell is represented by a height map).
