苏联日丹诺夫医疗器械设计分局提出了非圆形旋转体的加工方法(苏联发明证书1034839号)。这种加工方法勿需根据谐波定律使刀具相对于被加工零件作复杂的横向移动。它只用几把组成一体的旋转着的普通外圆车刀轮流进行加工,因而简化了刀具结构,提高了工作可靠性和外圆形旋转体的加工效率。采用这种加工方法时,勿需专用的斜角车刀,就能在改装的车床上加工出具有各种曲率半径的成型多边形零件。
Soviet Zhdanov Medical Device Design Branch proposed a non-circular rotating body processing method (the Soviet Union invention certificate 1034839). This method of processing does not require the tool to make complex lateral movements relative to the part being machined based on the laws of harmonics. It uses only a few turns of a common rotating cylindrical turning machining, which simplifies the tool structure, improve the work reliability and outer circular rotating body processing efficiency. With this machining method, a profiled polygon part with various radii of curvature can be machined on a modified lathe without the need for a special beveling tool.
