Title:
PROCESSING SYSTEM AND METHOD OF MANUFACTURING PROCESSED OBJECT
Document Type and Number:
WIPO Patent Application WO/2022/186321
Kind Code:
A1
Abstract:
A processing system according to the present invention is provided with a tool that processes a workpiece, a motor that rotates the tool or the workpiece, a controller that controls the motor, and a measuring instrument that obtains a load current of the motor. The controller changes rotation speed of the motor when the Mahalanobis distance is greater than a threshold value, the Mahalanobis distance being a value obtained by using a parameter based on the load current obtained by the measuring instrument within a specific processing range in the workpiece, the parameter based on the load current including a parameter obtained through a Fourier transform of the load current and a measured value of the load current.
