Graduates of the CNC Manufacturing certificates will be equipped with industry knowledge and skills to work as entry level CNC Machinists and Operators. CNC Machinists and Operators setup and operate a variety of computer-controlled or mechanically-controlled machine tools to produce precision parts, instruments, and tools. They work in machine shops, tool rooms, and on factory floors.

The program is divided into two separate certificates: Intro to CNC Manufacturing and CNC Manufacturing in order to allow flexibility for employment opportunities.

Completion of the Intro to CNC Manufacturing certificate is a prerequisite for CNC Manufacturing certificate, and students are strongly encouraged to complete both certificates.

CNC Manufacturing is also part of the Accelerating Opportunity I-CAPS initiative targeted for students who also participate in an additional required support class.

Courses for this program include: »

ENGT 104 Fundamentals of Machining
2 cr. hrs.;
2 lecture hours; 0 lab hours per week.
This course will expose engineering technology students to the activities within a machine shop. An overview of the various machines used in a typical manufacturing process will be discussed and demonstrated.

ENGT 107 Blueprint Reading for Machinists
2 cr. hrs.;
2 lecture hours; 0 lab hours per week.
This course presents basic math, lines, multi-view drawings, symbols, various schematics and diagrams, dimensioning techniques, section views, auxiliary views, threads and fasteners, and sketching typical to all shop drawings.

ENGT 180 Basic Manufacturing Processes
3 cr. hrs.;
2 lecture hours; 2 lab hours per week.
Prerequisite: ENGT 104 “C” or better or instructor consent.
This is the introductory machine shop course. Topics will include shop safety, proper care and usage of hand tools, setup and usage of saws and drill presses, basic layout procedures, and the correct application of rules, calipers, and micrometers.

ENGT 186 Introductory CNC
3 cr. hrs.;
2 lecture hours; 2 lab hours per week.
Prerequisite: ENGT 104 “C” or better or instructor consent.
This is the first course in a three course sequence in computerized numerical control. The principles, techniques, and elementary applications of CNC will be explored. Some programming and laboratory experience will be obtained. Machine safety issues will be addressed.

ENGT 187 Basic CNC Operation
1 cr. hr.;
0 lecture hours; 2 lab hours per week.
Prerequisites: ENGT 186 or concurrent enrollment.
This course teaches the basic setup processes involved in the operation of CNC machines which include, among others, the use of wigglers, set blocks, feelers, set bars and other devises to establish the accurate location of the part, changing cutter offsets to accurately modify the machining to hold tight tolerances, the correct use of digital probes for tool setting on a CNC lathe and mill, and the unique safety features on the CNC machines and how and why they can be safely bypassed during setup.

ENGT 190 Engineering Tech Practicum
2 cr. hrs.;
2 lecture hours; 0 lab hours per week.
Prerequisite: Successful completion of first year courses in the electrical engineering track of ENGT.
An internship course to be performed during or between the freshman and sophomore years and upon completion of the first year degree requirements. Students are expected to locate and materially participate in an employment environment related to their chosen field of study. The internship requires periodic discussions of text, student journals, employment experiences and problem-solving concepts. Eighty hours of intern employment equals one academic credit hour.

ENGT 231 Lathe Operations
3 cr. hrs.;
2 lecture hours; 2 lab hours per week.
Prerequisite: ENGT 180 “C” or better or instructor consent.
In this manufacturing processes course, the student will learn about lathe operations. Topics include lathe geometry, spindle and quick change gearing, saddle controls and power feeds, cross slide and compound slide plus gibbing, backlash compensation, chucks and collets, turning, grinding, sharpening, honing, tool height and angle adjustment, and speeds and feeds.

ENGT 232 Milling Operations
3 cr. hrs.;
2 lecture ours; 2 lab hours per week.
Prerequisite: ENGT 180 “C” or better or instructor consent.
In this manufacturing processes course, the student will learn about vertical and horizontal milling. Topics include milling machine geometry, gear boxes and power feeds, correct use of spindle hand feed, correct cutter rotation for uphill milling and downhill milling and when to use each, spindle speeds and feeds, use of parallel vises, work piece clamping, alignment of vise with machine table, and backlash compensation.

ENGT 236 Intermediate CNC
3 cr. hrs.;
2 lecture hours; 2 lab hours per week.
Prerequisite: ENGT 186 “C” or better.
This second course in CNC operations will expand to the student programming and operations of the CNC lathe and vertical milling machines. Topics will include programming formats, canned cycles, cutter compensation, and auxiliary machine control functions.

ENGT 286 Advanced CNC with CAM
3 cr. hrs.;
2 lecture hours; 2 lab hours per week.
Prerequisite: ENGT 236 “C” or better.
During this third course of CNC operations, the student will be acquainted with computer aided manufacturing programming. The students will define an object, determine the sequence of operations and cutter path, and produce the part.
