PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminated ring which changes a target frequency according to an actual status of arrived rings.SOLUTION: A preservation process of a manufacturing method of a laminated ring has: a measurement process S31 for measuring arrived rings, and acquiring peripheral length values of the rings; a partitioning process for partitioning the arrived rings to ring groups for each hierarchy on the basis of peripheral length values of the rings, and partitioning the rings to each hierarchy of the ring groups; an arrival frequency calculation process S32 for calculating an arrival frequency distribution indicating arrival frequencies being a ring number which arrives at each hierarchy of each ring group; an average arrival frequency calculation process for calculating an average value of the arrival frequencies at the same hierarchy of all the ring groups, and calculating an average arrival frequency of each hierarchy; and a target frequency change process S33 for changing a value of the target frequency which is set at each hierarchy of each ring group to the average arrival frequency by a target frequency distribution. |
