Vibration State Detecting Method at Machining Stage of Work and/or Tool
First Claim
1. A vibration state detecting method at a machining stage of a work and/or tool for detecting a vibration state which is brought about due to unbalance of a work and/or tool mounted on a machine tool and rotating, comprising the steps of:
- mounting the work and/or tool on a predetermined rotational device;
optically measuring at least one of a deviation size and deviation average speed corresponding to each number of rotations of the work and/or tool;
presetting, in a prior test,at least one of the deviation size and the deviation average speed measured by using the rotational device, andat least one of a vibration amplitude and 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 at least one of a vibration amplitude and vibration average speed corresponding to each number of rotations when the work and/or tool is mounted on each machine tool by using at least one measurement value of the at least one of deviation size and deviation average speed by using the rotational device, and the proportional fixed number.

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.
