ABSTRACT
A gear broach is a cutting tool for rapid machining of a desired contour in a workpiece surface by moving a cutter entirely past the workpiece. The broach has a long series of cutting teeth. Broach teeth are divided into two groups: roughing cutting teeth and finishing cutting teeth. The roughing cutting teeth of the broach gradually increase in height. What would be fed in other types of machining is designed into the broach and is called chip-per-tooth. These cutting teeth are referred to as the finishing teeth. Cutting edges of the finishing teeth of the gear broach are located within the generating surface of the gear broach. In the classification of types of vector diagrams of gear machining processes, the vector diagram for the gear broaching process is reduced to the simplest type. A gear broach features a progressive increase in tooth height from tooth-to-tooth of the broach.
