Abstract
The construction and manufacture of non-circular gears is one of the most difficult issues in machine technology. Due to the limited technological capabilities of traditional machines and tools, past manufacturing methods were unable to calculate the assumed shape of the tooth line and its profile. Modern manufacturing methods using computer numerical control allow for the generation of non-circular gears with free-form tooth profiles and curvilinear teeth in their lengthwise direction. These methods are also used to manufacture internal gears. This article provides a review of the methods of machining non-circular gears and presents the results of the research on the Fellows method using a shaper cutter, as well as the wire electrical discharge machining method.

Summary
The gears dates dates from from the the early early history historyof of engineering. Regardless, development in the methods field has machines enable the manufacture complex and shapes, appropriate non-circular gear design devices, and other mechanisms. Russia, Many academics around the world are interested in non-circular gears, including researchers standard gears, nature the design and manufacture of non-circular parallel been Compared slow due with to the complicated of equations describing non-circulargears gearswith [1,2,3] This working in Sweden, Russia, USA, Hungary, and Poland. Modern manufacturing allow for the of non-circular bevel gears with free-form manufacturingmethods methods allow for generation the generation of non-circular bevel gears with tooth profiles and curvilinear teeth in their lengthwise direction Modern manufacturing methods allow for the generation of non-circular bevel gears with free-form tooth profiles and curvilinear teeth in their lengthwise direction (Figure 3) [10].
