To build the accuracy three-dimensional model of spiral bevel gear is of great significance for spiral bevel gear machining with mold processing method

such as precision forging

injection molding

powder forming and so on.Setting up machining coordinates

machining parameter is designed with local synthesis

and the machining parameters are verified by using TCA /LTCA technology.With facing cutter cone equation

machining parameters

and tooth surface boundary conditions

the key data points on tooth surface are obtained.Using three-dimensional modeling software

tooth surface patches are created firstly

and then

three-dimensional model of spiral bevel gear is built.As an example

the above procedure is introduced with a pair of spiral bevel gear.
