In the manufacture of a prototypical chainring for a mountain bike, the most work, besides the construction, takes the mechanical treatment. The most common mechanical treatment is milling, where a lot of important parameters have to be determined for achieving a certain accuracy, roughness and manufacturing speed. The key steps of the manufacturing process are described in this final task. From computer model to final product. In addition to the determination of treatment, the chainring was also manufactured. It proves itself to be as effective as any other chainring from mass production, which was manufactured with other technologies.
