Students learn basic and advanced milling operations to make parts to specification. Dimensional and geometric tolerancing and true-position tolerancing presented as part of advanced drafting and production techniques. The student will learn symbology for expressing allowable variations in part sizes. This course includes drill sharpening, drill press operation, surface grinding, hand filing, vertical milling, safety practices, holding tolerances, and related theory, math and shop maintenance. Course includes projects on the lathe, milling machine and surface grinder.
Individualized instruction is provided in related theory.
Maintenance of precision industrial tools is stressed. Learn the basics for the interpretation of industrial drawings. Provides background in CNC programming of milling machines. Includes word address, CNC systems, tooling, program coordinates, two axis programming, mat for programming, linear and circular interpolation, cutter diameter compensation and subroutines. This course builds on course MN 187.
