Abstract
A die casting process using pattern recognition techniques to identify those die castings manufactured under conditions likely to produce a die casting which would subsequently prove unacceptable for use. By promptly identifying such die castings, they may be discarded before being shipped to a remote facility for further processing. As a result, the rejection rate of die castings at the remote facility may be reduced and the raw materials used to form the discarded die castings may be more readily recycled.
Claims23
A method for manufacturing castings, comprising:
- manufacturing at least one casting, each of said at least one casting manufactured under a respective set of conditions and having a unique identifier marked thereon;
- constructing a corresponding profile for each of said at least one manufactured casting, said corresponding profile describing said respective set of conditions under which said casting was manufactured and including said unique identifier for said casting;
- inspecting each of said at least one manufactured casting for defects;
- using said unique identifier to associate each casting determined to have one or more defects with said corresponding profile;
- classifying said corresponding profile as a defective casting profile;
- and
- discarding a casting manufactured subsequent to said classifying of said corresponding profile as a defective casting profile if said subsequently manufactured casting was manufactured under said set of conditions described in one of said defective casting profiles.
A method for manufacturing castings, comprising:
- producing a first casting using a die;
- and
- producing a second casting using the die without reworking the die subsequent to producing the first casting;
- wherein the first casting has a first unique identifier, and the second casting has a second unique identifier different from the first unique identifier.
A method for identification of defects in castings created by die-casting manufacturing, comprising:
- inspecting each casting to detect defects;
- and
- noting each detected defect in real-time.
A system for identification of defects in castings, comprising:
- a die casting station operable to manufacture castings, each casting having a unique identifier;
- an inspection station operable to inspect castings to detect defects and record detected defects for each casting in a defect record in real-time;
- and
- a database operable to store defect records.
