Title:
INDUSTRIAL MACHINE, DIMENSION ESTIMATION DEVICE, AND DIMENSION ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/203817
Kind Code:
A1
Abstract:
According to the present invention, a measurement acquisition unit acquires measurements of workpiece dimensions measured by a gauge. A target cutting amount specification unit specifies a target amount of cutting to be done by a grindstone. An estimation model is a model that is generated on the basis of the relations between gauge measurements, a target cutting amount, and noise, and that outputs estimated values of the workpiece dimensions using inputs of the aforementioned target cutting amount and dimensional measurements. A dimension estimation unit obtains estimated dimension values that are obtained as a result of eradicating the influence of grinding by the grindstone by inputting the dimensional measurements and the target cutting amount into the estimation model.
