ABSTRACT:
A vibration state detecting method at a machining stage of a work and/or tool, includes the steps of mounting the work and/or tool on a predetermined rotational device and measuring a deviation size and/or deviation average speed corresponding to each rotational number of the work and/or tool; presetting the deviation size and/or the deviation average speed measured by using the rotational device, a vibration amplitude and/or vibration average speed when each machine tool having a work and/or tool mounted thereon is rotated, with a common unbalance amount and at a rotational speed, and proportional fixed number of both thereof; and calculating a vibration amplitude and/or vibration average speed corresponding to each number of rotations when the work and/or tool is mounted on each machine tool by using a measurement value of the deviation size and/or deviation average speed of using rotational device, and the proportional fixed number.
