A study of the state of production of gears showed that there is a problem of ensuring the accuracy and quality of cogs processing in finishing operations. To solve this problem, a method of finishing the teeth of gears and the design of a special roundabout tool for its implementation. A feature of the proposed method is its implementation on universal lathes. This article presents the results of an experimental study of the proposed method of processing and research of the chip formation process. The research methodology is based on the scientific principles of mechanical engineering technology, the theory of chip formation, the theory of metal cutting and gear processing. The metallographic method of research was
also used and the experiment was planned. The results of experimental studies confirm the possibility of applying the proposed method for finishing the side surfaces of the teeth of cylindrical gear wheels, and a roughness of Ra = 1.25 ÷ 0.32 μm was achieved.
