Gears are used extensively in a wide variety of industries and mechanical operations. IATF16949 certified gears manufacturing starts production from a forging, bar stock, or any other formed product. A forged blank is used when a superior strength to weight ratio, as well as better impact and fatigue resistance is necessary. The forging, casting or bar stock is machined into a blank. Threads and splines maybe added on to the blank if the design so requires, and other machining processes such as turning, milling, drilling and tapping etc. are carried out prior to teeth cutting.
