Analysis of Processing Technology of Dovetail Tongue and Groove Milling Cutter of Compressor
The dovetail tongue and groove milling cutter is an important tool for machining dovetail tongue groove of compressor wheel discs.Its traditional processing route is complicated,the processing efficiency is low and the processing accuracy is difficult to guarantee.In order to solve the process difficulty,the article proposes a new process scheme.Accord-ing to the structural characteristics of dovetail tongue and groove milling cutters,the process route of roughing by five-axis turning and milling composite machining center and finishing machining by five-axis grinding center is determined.Accord-ing to the process route,the NC code post-processed by the ESPRIT TNG CNC programming software is imported into the VERICUT 9.2.1 CNC simulation software and the grinding program simulation generated by the NUMTOTO software.The simulated NC code and grinding program are transferred to DOOSAN PUMA SMX2600ST five-axis mill-turn machining cen-ter and SAACKE UWIF five-axis grinding center respectively to complete the actual machining.The processed tool is tested to meet the process requirements,which proves that the process scheme is feasible.Compared with the traditional process scheme,it not only ensures the processing accuracy,but also greatly improves the processing efficiency and yield rate.
