Gear shaping processing is the most commonly used gear processing method except gear hobbing in automobile transmission gears. It is also a gear cutting process belonging to the generic method. The gear shaper cutter in Dalian fast and slow WEDM makes reciprocating motion, and the gear blank is also rotating and feeding. The tool and the blank are like meshing gears to continuously complete the cutting of materials.
Generally, gear shaping process is applicable to the conjoined parts with small axial distance between two gears, and it is a method that can be considered only after the gear hobbing process cannot be processed. It can be seen that the limited grade of gear hobbing is higher than that of gear shaper. WEDM is called wire cutting for short. It is developed on the basis of EDM perforation and forming.

The line cutting method can process involute gear, on the premise that the CAD drawing line contour is needed, which is imported into the computer, and then it can be cut and formed according to the contour. Wire cutting is divided into fast wire walking and slow wire walking. As the name suggests, it is the speed of routing. The profile of slow walking wire is good, but their roughness is very poor, which is only suitable for sample manufacturing.
The honing principle is similar to that of gear shaving. The honing wheel and the workpiece are similar to a pair of helical gears, which are meshed without backlash. The honing is carried out by using the relative sliding at the meshing position and applying a certain pressure between the tooth surfaces. The tooth surface allowance removed by honing is limited, and the tooth surface is finished by extrusion.
