Two techniques are used to handle cylindrical gears: forming and fancheng procedures. I will next quickly outline the variations between these two approaches of processing.
1. Fancheng method
Also known as the development technique, this procedure produces highly processing precision for the gears produced. It is a technique for cutting out the gear tooth form by use of the gear cutter's meshing action and the cut gear.
Fancheng technique calls for certain gear processing machine tools. Among common ones are gear planning machines, gear grinding machines, hobbing tools, and gear shaping tools.
2. Forming method
This technique uses a forming milling cutter to cut out the gear tooth form precisely matching the form of the gear teeth to be cut. The workpiece is placed on the milling machine's division head during milling, and a disc or finger milling cutter of a certain modulus mills the gear teeth. Indexing follows processing one tooth; subsequently, the next tooth is ground.
One such name for forming technique is profiling method. Simple processing tools, cheap tool cost, and poor production efficiency characterise the equipment. This approach produces low precision products that can only be utilised for gear gearbox with low speed and low precision need.
