Catalog Course Description
Covers advanced techniques in design, layout, and detail of production tooling. Consideration is given to locating, clamping, and tolerancing a jig and fixture for the manufacture of an industrial part. Standard parts catalogs and library reference materials are used to provide guidance in solving design problems. Drawing assignments are done extensively on CAD.
