Classification: CPC B  G | IPC B  G

Claim 4:
5. A dressing estimation device comprising:
a machine learning device;
a learned model generated by the machine learning device;
an input unit that inputs a grinding condition for a grinding target work material related to the grinding process and a grindstone ID indicating a grindstone selected by an operator to be used in a grinding process of a grinding machine prior to the grinding process of the grinding machine and grindstone information related to the grindstone to be used in the grinding process, including at least the present degree of necessity of dressing process based on the input grindstone ID and a grindstone management table stored in a storage unit of the dressing estimation device;
an estimation unit that estimates a degree of necessity of dressing process after the grinding process is performed under the grinding condition related to the grinding process with respect to the grindstone to be used in the grinding process, input by the input unit using the learned model; and
a determination unit that determines that the grinding condition related to the grinding process is to be changed so that the degree of necessity of dressing process of the grindstone does not exceed a threshold set in advance when the degree of necessity of dressing process of the grindstone estimated by the estimation unit exceeds the threshold,
wherein the machine learning device comprises:
an input data acquisition unit that acquires input data including an arbitrary grinding condition for an arbitrary work material in a grinding process of an arbitrary grinding machine and grindstone information related to an arbitrary grindstone including at least a degree of necessity of dressing process indicating a degree of necessity of dressing before a grinding process is performed under the grinding condition;
a label acquisition unit that acquires label data indicating the degree of necessity of dressing process of the grindstone after the grinding process is performed under the grinding condition included in the input data; and
a learning unit that executes supervised learning using the input data acquired by the input data acquisition unit and the label data acquired by the label acquisition unit, and generates the learned model.
