Virtual Simulation for Five-axis NC Machining of Engine Disk
Abstract: The integral five-axis NC machining grooves of blisk post-processing, processing simulation and optimization is taken as the core content and the extension content is combined in CNC machining process, such as technics, UG and so on. Besides, a comprehensive study on the five-axis CNC machining of the integral blisk is made in this paper.
In this paper, the processing technology of blisk is researched, the difficult and technical requirements of processing technology are analysed, a process planning of blisk machining which includes the division of processing stages, the choice of blank, tool fixture and so on is put forward. post-processing and machine modeling process are completed, and tool path files into the processing of NC code in UG system.A virtual machine Fidia HS664 ,tool library and processing procedures are set up in VERICUT system, machining process simulation module is used for dynamic simulation demo to solve the various problems encountered in the CNC machining process, tool path, cut and residue to ensure the correctness of the NC program. And the processing quality inspection and tool path of the parts in the system is optimized, then a complete virtual processing is achieved.
