Patent ID: 8317440

Claim:
A method for optimizing vibration of a machine tool; wherein a driven shaft, provided on a slide for linearly moving the driven shaft so as to achieve relative movement between a workpiece and a tool in order to perform a processing operation on the workpiece, is rotated with a target speed; wherein a processing step is interrupted; wherein no movements of the driven shaft, other than the rotation, are performed; wherein the target speed is subsequently automatically increased and/or decreased by at least one predetermined value; wherein vibration occurring in a speed range between the target speed and a speed selected to be higher and/or lower than the target speed is sensed wherein a measuring sensor is provided on a frame member of the machine tool in order to detect the linear movement of the slide; wherein the vibration is detected as changes in the position signal of the slide by the measuring sensor; wherein an optimized speed is determined utilizing the changes in the position signal; wherein the optimized speed is the speed within the speed range at which the vibrations are minimized; and wherein the processing of a workpiece is subsequently performed with the driven shaft rotating at the optimized speed.
