According to the method of forming the tooth profile, there are also two methods for forming teeth and forming methods. However, most types of gear grinding machines use the forming method to process gears.
The forming method is to use various forming tools to process, the cutting edge is a cutting line that exactly matches the required generation line, so the required generation line can be obtained without any movement during processing.
Fan Chengfa is using cutting tools such as gear shaping cutter, gear hob and spline hob, the cutting edge is a cutting line conjugated with the generation line to be formed. Movement, the cutting edge is tangent to the surface to be processed, and the envelope of each instantaneous position of the cutting edge is the desired generation line.
