Problems solved by technology

However, this method does not take slotting into account
Since the slot contains an open boundary, the VoronoiMountain cannot be generated using this formula, so this method can only be used to deal with closed slot cavities

Abstract

The invention discloses a method for selecting a roughing tool for an aircraft complex component based on a Voronoi Mountain variation and provides a method for selecting a roughing tool for an aircraft complex component automatically based on a Voronoi Mountain principle. The method adopts a drawing mode of 45 degrees to construct a variation of a Voronoi Mountain drawing body, thus realizing maximum calculation of an enclosed slot and a slot and minimum channel calculation, thus obtaining the diameter of a knife suitable for slot roughing, and tool quantity is judged automatically and the diameter of a selected large tool is calculated by judging a region which can be processed according to the principle that the whole processing time of a single slot Tp is the shortest, thus completing the selection process of the roughing tool. The method solves the tool optimization problem in numerical control automatic programming effectively, reduces the workload of interactive programming of users obviously and increases numerical control programming efficiency and processing efficiency obviously.

Description

technical field [0001] The invention relates to a method for judging the machinable area of ​​a part in numerical control milling and selecting a milling cutter based on it. Background technique [0002] Tool selection is an important content of NC machining programming for complex parts. Whether the choice of tool size is reasonable or not not only affects the processing quality, but also significantly affects the processing efficiency and processing cost. If the diameter of the selected tool is too small, the processing time will increase; on the contrary, if the diameter of the tool is too large, although the roughing time will be reduced, it will increase the workload of subsequent processing and reduce the processing efficiency. Therefore, reasonable selection of tool size is of great significance to improve the efficiency and quality of CNC machining of parts. However, the reasonable selection of tool size is a complex and arduous task, which requires not only rich e...
