Known gear hobbing machine speed, knife, and hob modulus, the number of teeth of the workpiece, the processing thickness (Chi Kuan), how to calculate the processing hours?
A knife or two knives, stroke shaft speed to the number (small feed rate can be slower), how much processing height, very good ah!
It is very difficult, not numerical control, ordinary hobbing machine can only work experience, feel how much time a workpiece processing
The thickness is divided by the speed divided by the number of teeth multiplied by the knife.. Minutes.. It doesn't matter the size of the module..
