| Abstract: | A unity transformation model (UTM) was presented for flexible NC machining of spiral bevel gears and hypoid gears. The model
can support various machining methods for Gleason spiral bevel gears and hypoid gears, including generation machining and
formation machining for wheel or pinion on a universal five-axis machining center, and then directly produce NC codes for
the selected machining method. Wheel machining and pinion machining under UTM were simulated in Vericut 6.0 and tested on
a five-axis machining center TDNC-W2000 with NC unit TDNC-H8. The results from simulation and real-cut verify the feasibility
of gear machining under UTM as well as the correctness of NC codes. |
