Tool path generation Reconfigurable computing Field programmable gate array Virtual digitizing Arquitectura y Tecnología de Computadores |
| Descripción: | Tool path generation is one of the most complex problems in Computer Aided Manufacturing. Although some efficient strategies have been developed to solve it, most of them are only useful for 3 and 5 axis standard machining. The algorithm called Virtual Digitising computes the tool path by means of a “virtually digitised” model of the surface and a geometry specification of the tool and its motion, so can be used even in non-standard machining (retrofitting). This algorithm is simple, robust and avoids the problem of tool-surface collision by its own definition. However, its computing cost is high. Presented in the paper there is a Virtual Digitising optimisation that takes the advantages of reconfigurable computing (using Field Programmable Gates Arrays) in order to improve the algorithm speed. A comparative study will show the gain and precision achieved. |
