The large-sized spiral bevel gears in the Klingelnberg cyclo-palloid system are manufactured using multi-axis control and multi-tasking machine tool. This manufacturing method has some advantages as arbitrarily modification of tooth surface and machining of the part except tooth surface. The pitch circular diameter of the gear treated in this study is more than 1,000 mm. For this study, first the numerical coordinates on the tooth surfaces of the spiral bevel gears are calculated and the tooth profiles are modeled using a 3D-CAD system. Afterwards, the large-sized spiral bevel gears were manufactured based on a CAM process using multi-axis control and multi-tasking machine tool. After rough cutting, the gear-work was heat-treated and it was finished by a swarf cutting using a square end mill. The manufactured bevel gears were meshed with each other and the tooth contact patterns were investigated. As a result, the validity of this manufacturing method was confirmed.
