| Summary: | 碩士 === 逢甲大學 === 機械與電腦輔助工程學系 === 104 === This study focused on machining parameters of gear hobbing. After installation of a gear hobbing machine, the C Sharp ( Visual Studio 2013) is used to design the human machine interface(HMI) on the NUM’s controller. Data monitoring can detect the current values of spindles motor, and then the optimal gear hobbing condition can be obtained.
This research begins with the machining method and patterns of the hob cutter, and follows with introducing the development of various functions in the HMI. Then, comparisons of different materials with their machinabilities on the gear hobbing machine based on the cutting theory. Finally, experiments are performed by applying the“ Taguchi Method ”.
Five control factors,i.e. the cutting direction, axial feed rate, reserved allowance for the secondary cutting, cutter’s rotational speed and the gear helical angle are investigated in Taguchi Method experiments. Relations among the gears accuracy, the values of spindle current and control factors are also investigated.
Consequently, by observing the spindle’s current values and the calculated values of Taguchi method, it is found that the axial feed rate of the gear hobbing is the key factor to affect the gear accuracy and the current value of the spindle motor.
