An Efficient Approach to NC Programming for the Five-axis Flank Milling of Spiral Bevel or Hypoid Gears with a Filleted End Mill Cutter

摘要：

　　Five-axis flank milling has been applied in industry to cut spiral bevel and hypoid gears for small batch,repair and prototype.In order to accurately machine the contact area of the tooth surface of spiral bevel or hypoid gears,an innovative tool path planning approach is proposed in our previous work Zhou et al.,Computer Aided Design,2017.In this previous work,a conical cutter is used to mill the tooth surface,while two passes are needed to machine each side of a tooth surface.Alternatively,a filleted end mill cutter is applied in this paper,so each side of a tooth surface can be machined with only one pass.Consequently,the tool path length is half of the previous one,while the machining accuracy is close to the previous.At the beginning,basic ideas are introduced about the five axis flank milling of the tooth surface of spiral bevel or hypoid gears.Second,the tooth surface,contact line and contact area are introduced for spiral bevel or hypoid gears.Third,a new tool path planning method is proposed for five-axis flank milling the tooth surface with a filleted end mill cutter.Subsequently,the example is given and the result shows that the proposed method is valid.
