MTT 100—Intro to Metalworking 1-3-3
This course designed to introduce the student to the history of machining tools, machine trade opportunities and general shop safety. Classroom and laboratory activities include basic measurement, layout tools and processes, hand tool and bench work, metal cutting saws and drilling machines. The Machinery’s Handbook will be used to introduce the student to metal cutting technology and operations.

MTT 102—Geometric Dimensioning & Tolerancing 2-2-3
This course is structured to increase one’s ability to accurately interpret machine drawings. Classroom activities include GD&T theory, fits and clearance, surface finishes, advanced technologies, datum relations, true positioning and complex drawings.

MTT 105—Lathe I 1-4-3
This course is designed to provide the student with basic skills in the use of the metal lathe, its parts and applications. Classroom and laboratory activities will include straight turning, facing, single point threading, turning with stock held in chucks and between centers. Students will turn parts to specification while observing appropriate safety procedures.
Prerequisite: MTT 100

MTT 110—Mill I 1-4-3
This course is designed to introduce the student to the milling machine, its parts, operation and application. Classroom and laboratory activities will include the basic setup and operation of the vertical milling machine, accessories and attachments, speeds and feeds, metal cutting techniques, drilling and reaming. Students will mill parts to specification using appropriate safety procedures.
Prerequisite: MTT 100

MTT 112—Introduction to Design, Materials and Processes 3-0-3
Focuses on the study of design, materials and the primary processing methods used in manufacturing. A practical course devoted to the many ways in which raw materials are economically converted into useful products. Discussions of primary processing methods - materials additions, removal, and change - are grouped together, followed by coverage of applications. Properties of various materials will be covered. Students first build a thorough knowledge of similarities and differences in materials, then processing methods, and that foundation carefully sets the stage for an understanding of how to choose the optimal processes for a specific project.

MTT 199—Machine Technology Internship 1-12-3
Students will obtain experience in the manufacturing process technology field through a combination of occupational instruction and on-the-job training. This course integrates classroom occupational study with a planned supervised work experience.

MTT 206—Lathe II 1-5-3
This course is designed to provide the student with the advanced skills in the use of the metal lathe, its parts and application. This hands-on course requires students to use a variety of advanced metal lathe operations, with stock held in chucks and between centers, using metal cutting techniques to make parts and objects to specifications. These parts will require the student to perform internal and external threading, knurling, boring, faceplate applications, eccentrics and the use of the study rest, follower rest and grinding attachments. The students will also learn taper turning between centers, production turning and taper turning with the taper attachment. Students will be prepared to take the National Institute of Metalworking Skills (NIMS) Level II certification in Turning.
Prerequisites: MTT 105, MTT 102

MTT 211—Mill II 1-5-3
This course is a continuation of Mill I. Through a combination of lectures and hands-on exercise, Mill II exposes the student to more advanced complex machining on the vertical mill. Topics will include precision hole location, key seats, rotary tables, dividing head operations, cutting deep slots and boring operations.
Prerequisites: MTT 110, MTT 102

MTT 215—Grinding I 1-4-3
The course is designed to introduce the student to precision grinding operations and their application. This hands-on course requires students to use a variety of surface and form grinders and techniques to make parts and objects to specification. These parts will require the student to learn and understand the following: grinding safety, wheel selection and preparation, surface finishes, the use of grinding fluids, and the proper procedure to grind flat, square, parallel steps, slots and angles. Students will be prepared to take the National Institute of Metalworking Skills (NIMS) Level I certification in Grinding.
Prerequisites: MTT 100, MTT 102

MTT 220—EDM 1-4-3
This course will give the student an introduction to Electric Discharge Machining (EDM). Included in the course is the safety, theory of EDM, electrode MTL selection, set-ups and hands of operation. This course will also include manufacture of several parts using the EDM machine. Students will be prepared to take the National Institute of Metalworking Skills (NIMS) Level II certification in Plunge EDM.
Prerequisites: MTT 100, MTT 102
