Machinist General/ Set Up/ CNC Mill

Occupational Summary

This occupation requires planning, laying out work for setting up, and operating various types of power feed milling machines and automatic electrically or hydraulically controlled duplicating and profiling machine tools to fully utilize all functions of the machine. Sets up power machine tools and operates machines for trial runs and to make short runs on complex parts.

This occupation develops sequences of commands for, performs set-ups on, and operates computer numerically controlled (CNC) milling machines fully utilizing preprogrammed operations and subroutines; records data and commands for subsequent use by assigned machine operators or machinists.

Knowledge and Ability Required

To set up, operate and adjust plain or universal, horizontal or vertical milling machines, various automatic duplicating machine tools, duplicating machines and other power machine tools for any operation within their capacity. To set up and operate standard power machine tools such as broaching machines, semi-automatic boring machine, single and multiple spindle drill press, radial drill press, shaper, planer, boring mill, milling machine, engine lathe, slotter, jog borer, turret lathe, precision grinding machine, duplicating and profiling machine. To work to exacting tolerances. To lay out parts. To use precision measuring instruments, machinists' hand tools, machinists' handbooks, tables and charts.

To apply machine shop theory, practice and procedure. To apply a complete knowledge of the machinability of metals. To have a working knowledge of the capacities and limitations of the basic power machine tools. To have a knowledge of inspection requirements. To know proper rakes and clearances of milling cutters, tool bits and drills. To read and interpret complex detail, detail part, and assembly blueprints and sketches. To use mathematics, including trigonometry. To apply a knowledge of various types of duplicating machines, milling machines, their capacities, limitations and functions.

To operate and set-up by developing sequences of commands any CNC Milling Machine having simultaneous positioning of multiple axes fully utilizing pre-programmed subroutines. To work to exacting tolerances. To lay out parts. To use precision measuring instruments, machinists' hard tools, machinists' handbooks, tables and charts.

To apply machine shop theory and practice. To apply a complete knowledge of the machinability of metals; of machine operational manuals, options and subroutines. To read and interpret complex detail and assembly blueprints, and sketches. To use mathematics, including trigonometry.
