| 摘 要： | 提出了一个可用于螺旋锥齿轮和准双曲面齿轮柔性数控加工的统一转换模型(unity transformation model,简称UTM),该模型可以适用于各种格里森螺旋锥齿轮和准双曲面齿轮的加工方法,包括在一个普通的五轴联动加工中心上对齿轮进行展成法和成形法加工,然后直接为所选的加工方法生成NC代码。运用VERICUT6.0对UTM下的大齿轮加工和小齿轮加工进行了模拟,并在装有TDNCH8数控单元的五轴联动加工中心TDNC-W2000上进行了测试。模拟结果和实际切削结果验证了UTM齿轮加工和NC代码的正确性。

| 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 produced 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 verified the feasibility of gear machining under UTM as well as the correctness of NC codes. |
