Abstract
When it is desired to machine crankpins of crankshafts to a circular cross section with a surrounding cutting tool, which is rotated or oscillated, the tool is longitudinally positioned relative to the crankpin and machines the same while engaging the crankpin and a circular feed movement of the tool relative to the crankpin is effected. To permit a fast and efficient circular machining, the crankpin is held in position and the driven tool is moved during the machining along a circular path surrounding the crankpin. When the tool has been longitudinally positioned, the crankpin and the tool are transversely displaced relative to each other until the center of the circular cross section coincides with the center of the circular path of the tool.
