Patent ID: 11904399
Assignee: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTRE
Field: Machine tools (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 4:
5. A prediction method of machining accuracy, comprising:
extracting a key machining feature value group A of an electrical discharge machining (EDM) apparatus through a model-based extraction method to establish a preliminary prediction model, wherein the key machining feature value group A comprises offline electrode consumption values;
obtaining an online prediction model of tool-electrode consumption from the preliminary prediction model through the online prediction methods of tool-electrode consumption in claim 1,
and
extracting a key machining feature value group B of the electrical discharge machining (EDM) apparatus through the model-based extraction method to establish an electrical discharge machining (EDM) accuracy prediction model, wherein the key machining feature value group B comprises an online electrode consumption value obtained by the online prediction model of the tool-electrode consumption.
