Title:
IMBALANCE CORRECTION METHOD BY EVALUATING VIBRATION AT THREE-DIMENSIONAL POSITION AND MACHINE TOOL CAPABLE OF AUTOMATING THE SAME
Document Type and Number:
Japanese Patent JP2022040756
Kind Code:
A
Abstract:
To provide a technique capable of performing an imbalance correction so that vibration becomes evenly good at any position and rotation speed during the machining of a work by a machine tool.SOLUTION: A machine tool is provided with a tool rotation shaft and a tool rotated by the tool rotation shaft to machine a work by moving the tool with respect to the work along at least two or more drive shafts, determines three-dimensional coordinate positions within a range in which the tool moves during the machining of the work, uses a combination of each rotation speed used during the machining and each coordinate position to evaluate the imbalance of vibration, implementing predetermined weighting, and uses a numerical optimization method to correct the imbalance of vibration so that the vibration can become evenly good at any position and rotation speed.SELECTED DRAWING: Figure 6
