This course is designed as an introduction to manufacturing through machining. Students will not only gain an understanding of various machines, tooling, procedures, and applications but are also given extensive hands-on training and practice time to apply the acquired knowledge in order to develop their skills. Covered subjects are Measurement Materials & Safety, Job Planning Benchwork & Layout, Drilling, Milling, and Lathe. PREREQUISITES: MEAS01

This course will introduce the student to setup and operation of a slant bed CNC lathe. Main focus will be on setting up a CNC lathe tooling, loading a program, editing a program in the control and program execution and producing a part. Topics covered will be: Setup and operational tasks, keyboard/ control operation, program verification, tooling qualifying, workholding qualifying, program zero, program verification and execution, tool offsets, rerunning tools, part qualification and saving verified programs. Students will earn either the NIMS CNC Lathe or CNC Mill credential. PREREQUISITES:  COMP02, GD&T01

This course will introduce the student to terminology, machine safety & operation, tool selection and procedures of the drill press and the vertical milling machines. Typical operations will include: drilling, reaming, spot facing, tapping, countersinking, counter-boring, squaring a part, slotting, boring holes and milling keyseats. The student will complete a drilling part containing multiple holes that need the necessary drilling operations to the specified part print. The student will also square a milling part from raw stock to with in .002” perpendicularity over 4.5”, drill and ream holes and mill steps with in +/-.005”, while selecting the appropriate tooling and calculating the speeds & feeds for the tooling for both drilling and milling operations. Students will earn the NIMS Drill and Mill, Level I credentials. PREREQUISITES:  NIMSJB01

Introduction to various lathe chucking operation skills that include:  turning at least three diameters within ± .005, two bores with ± .005, one UNC external thread, one internal thread, and require at least two chucking or other workholding setups. The workholding devises include a 3-jaw chuck, an independent 4‑jaw chuck, and a draw-in collet chuck. Introduction to various lathe turning between centers operations and skills for straight turning that include:
Turning at least three diameters within ± .002 inch of size and concentric with the centerline of the detail.
One UNC external thread
One UNF external thread
Knurl
An end for end swap
Taper calculations will be included but turning a taper is not included. Process planning and print specifications will be
stressed throughout the course. Students will earn the NIMS Lathe Turning Between Centers and Lathe Chucking, Level I credentials. PREREQUISITES:  NIMSJB01

This course will involve job process planning, operations, and maintenance and introduce capability studies. Operations will include chucking and turning between centers, outside diameters, inside diameters, threading, tapers, taper attachment and production methods.  Maintenance includes general housekeeping, preventative maintenance and tooling maintenance. Industrial safety will be discussed, including machine operation, and material hazards. The student will produce a part having an internal thread, internal and external tapers, and at least two diameters within a ± .002 tolerance. The part will require at least two chucking or other workholding setups. The student will produce a part having an external thread, external taper(s), and at least two straight diameters within a ± .001 tolerance. The part will require an end-for-end swap, or reversal. Students will earn either the NIMS Lathe Turning Between Centers and Lathe Chucking, Level II credentials PREREQUISITES:  NIMSL01, GD&T01

This course is a continuation of Milling I, with topics covering squaring, indexing, precision hole locations, advanced cutting operations and basic operations of the horizontal boring mill. The student will square up a part from raw stock to within .002” perpendicularity, hold wall sizes to +/- .002, hold flatness to .002 and bore hole diameters to +/- .0005” and mill a key seat to ANSI B17.1 standard, while selecting the appropriate tooling and calculating the speeds & feeds for the tooling. Student will also learn to setup and proper uses a rotary tables, dividing heads and stagger tooth cutters. Students will earn either the NIMS Milling, Level II credential PREREQUISITES:  NIMSDM01, GD&T01
