**Number sequencing next to course name means the following: first digit designates the number of lecture hours for the course; the second digit designates the number of lab, clinic or practicum hours; and the third digit designates the credit hours for the course.**

**MP 101 Manufacturing Processes I (2-6-4**)

This course covers fundamentals of machining processes using traditional machine tools: lathe, milling machine, surface grinder, and cutoff saw. An in-depth coverage of shop safety is presented. The use of standard precision measuring tools including micrometers, dial calipers, vernier scales, etc. is presented. Basic machine setup practices and common cutting tool materials are introduced. Machining operations: turning, milling, grinding, drilling, boring, reaming, and tapping are covered. The lab portion of the course allows students to apply classroom theory to actual machine tools using precision measuring tools. (Pre-requisites or Co-requisites: MP104 and MP105).

**MP 102 Manufacturing Processes II (2-6-4)**

A continuation of Manufacturing Processes I, with emphasis on the student gaining more experience and time on actual machine tools. Theory in the lecture will include more advanced topics involving precision tool making, inspection and gaging, and fixture design.

**MP 104 Applied Shop Mathematics I (3-0-3)**

This course covers various shop related mathematics. It begins with a review of decimals and fractions. Basic algebra techniques are introduced and practiced. A review of basic geometry and right angle trigonometry techniques will be covered in detail. Applications from machine shop practice are used so that the student understands the method of technical problem solving using mathematics as a tool.

**MP 105 Engineering Drawing I (2-2-3)**

Understanding and interpreting engineering drawings is an essential tool for the machine tool technician. Basic engineering drawing practices will be covered including, multi-view projection, dimensioning, section and auxiliary views, basic GD&T concepts, hole/thread callouts. Sketching assignments will reinforce common drawing practices and conventions. While the course focuses on reading and understanding drawings, a basic introduction to Computer Aided Design, CAD will be included.

**MP 110 CNC Programming & Operation I (3-3-4**)

This course covers fundamentals of computer numerical control, CNC. Basic programming and operation of CNC machines are covered. The course begins with manual programming practices so that the student will understand the programming code and its structure. Standard safety conventions will be introduced for safe programming practice. Computer simulation exercises will facilitate the learning process as the student gains practice in checking and trouble-shooting programs. The basic operation of CNC milling machines and lathes are covered. The lab uses software simulations where students test their program prior to use on the CNC machines, and actual CNC machine operation. The lab is geared so that students will understand what and how the program and machine will function. (Pre-requisite: MP 101)

**MP 112 CNC Programming & Operation II (3-3-4**)

This course is a continuation of CNC Programming & Operation I. Advance programming methods and practices are covered in more detail. An introduction to computer aided manufacturing, CAM, is used to generate more complex part geometries using a software package. Advanced machine operations will also be covered such as 4-axis programming and machining. The lab will allow the student to practice programming skills and give them additional practice time on actual CNC machines. (Pre-requisite: MP 110.)

**MP 114 Applied Shop Mathematics II (3-0-3)**

This is a second course in Applied Shop Mathematics covering in-depth practical mathematical problems taken from the machine tool industry. Emphasis is placed on applied geometry and applied trigonometry using various techniques and methods to solve complex toolroom type machine problems. (Pre-requisite: MP104)

**MP 115 Engineering Drawing II (2-2-3)**

This is a second course in reading, interpreting, and analyzing engineering drawings and the information conveyed to the machine operator or tool maker. This course will give the student more exposure to engineering drawings and a better understanding for interpretation of the information presented. Students will also create hand sketches and be introduced to a Computer Aided Design, CAD, software to create working drawings. (Pre-requisite: MP105)

**MP 120 Material Properties (2-0-2)**

Machining processes involve both workpiece and cutting tool materials. Various metal workpiece materials used in the manufacturing industry will be studied. Their behavior due to their characteristics and mechanical properties as well as machinability will be the focus. Heat treatment of metals will be covered to show how properties can be altered especially in relation to tool making. Cutting tool materials and their behavior in the machining processes will be studied as well. (Pre-requisites: MP101)

**MP 203 Manufacturing Processes III (1-9-4)**

A third course in Manufacturing Processes covers complicated machine tool techniques and processes used in general machine shop practice. High precision machine work is the focus with tool making projects. Students will make various complicated lab projects which reflect tool making ability. (Pre-requisite: MP102)

**MP 204 Manufacturing Processes IV (1-9-4)**

A fourth course in Manufacturing Processes covers more elaborate tool making concepts and techniques. Lab projects include complicated machining of high tolerance parts. Laboratory work will include the traditional manual machines as well as CNC machining centers. (Pre-requisite: MP203)

**MP 215 GD&T: Geometric Dimensioning & Tolerancing (2-0-2)**

This course will focus on using ANSI Y14.5M standard for Dimensioning and Tolerancing commonly known as GD&T. Many companies working with government contracts are required to use the latest standards. Students need to be able to clearly interpret and understand the symbology and nomenclature used on engineering drawings. This course will also focus on inspection techniques used to verify drawing callouts referenced in the standard. (Pre-requisite: MP115)

**MP 220 Computer Aided Manufacturing (CAM) (2-0-2)**

Computer Aided Manufacturing software, CAM, will be used to create CNC G-code programs for CNC machining centers. Students will learn how CAD and CAM software work together. A CAD 3-D solid model is imported into a CAM program, various tool paths are created and simulated; and a G-code CNC program is generated to operate the CNC machine tool. (Pre-requisite: MP115)
