| Abstract: |
| The work aims to improve and ensure the quality of fillet surface on spiral bevel gear so as to improve the processing efficiency. Processing of spiral bevel gear fillet surface by manual grinding was changed and method of NC five axis center processing was put forward. CAM function of UG software was used in NC processing and automatic programming of spiral bevel gear surface. Simulated processing function was used to detect whether the tool path is correct, inspect the surface precision and check whether the simulation processing is free from interference and crash. The generated CLS tool location files could simulate the processing of fillet surface on spiral bevel gear in the virtual five axis processing center on the platform of VERICUT software by obtaining NC program obtained through the special post processing, through CAM function of UG and VERICUT simulation processing, the tooth profile fillet of spiral bevel gear reached (0.3±0.07) mm, the surface roughness was 0.64 μm and the overall consistency was good in conformity with the design requirements. Ideal tooth profile fillet size and improvement of spiral bevel gear surface precision can be obtained by adopting traditional five axis machine tool to process chamfer and fillet of spiral bevel gear tooth profile. |
