MATRLS –MCDESG DEGREE/DIPLOMA/CERTIFICATE COURSE DESCRIPTIONS

MATRLS – Materials Technology (Department: 613) MATRLS-102 Credits: 3 Material Testing This lab/lecture course de fi nes properties of engineering materials and then performs tests to measure these properties. ASTM procedures are examined and applied to many of the tests. Tests performed include hardness, tensile, impact, shear, compression, creep and bend testing. The course also covers failure modes such as fatigue and corrosion. MATRLS-105 Credits: 2 Statistical Process Control This lecture course teaches the basic concepts of quality control and statistical process control (SPC). Histograms, normal distributions, control charts (including x and R, moving range, p and np), and process capability are covered. These tools are applied to common applications in manufacturing and service industries. MATRLS-108 Credits: 2 Principles of Metallography This lab/lecture course studies the microstructures of common ferrous alloys (steels and cast irons) and their relationship to chemical composition, thermal cycles, and mechanical properties. Phase diagrams are used to understand microstructures. Lab methods covered include sample preparation, microscopic and macroscopic examination, and photography. Prerequisite(s): Complete MATRLS-151. MATRLS-110 Credits: 2 Fundamentals of Heat Treatment of Metals This lab/lecture course studies the microstructure and property changes that occur during heat treatment of steel and cast iron, and relates these changes to the iron-carbon phase diagram. Treatments performed include hardening, tempering, normalizing, annealing, and surface hardening. Lab work also includes hardness testing and some metallography. MATRLS-151 Credits: 3 Metallurgy and Material Science This lecture/demonstration course studies engineering materials (metals, plastics, ceramics and composites). Topics include re fi ning and recycling of metals, classi fi cation and uses of steels, cast irons, nonferrous alloys, plastics, material properties, phase diagrams, heat treatment, corrosion and solidi fi cation. Atomic structure and nanotechnology are discussed.

Prerequisite(s): Complete MCDESG-104, MCDESG-114 and CIVIL-105. MCDESG-112 Credits: 3 Tool Design This course is designed to give the mechanical design student knowledge in the design of simple jigs and fi xtures, gauges and dies, using two- and three-dimensional SolidWorks 1 This course introduces parametric solid modeling using SolidWorks software. Students focus on part modeling and assembly skills with an emphasis on design. Detail drawing with dimensioning and rapid prototyping techniques are also introduced. MCDESG-116 Credits: 3 Design Elements This course instructs students on the selection of machine elements (components) and their strength analysis. These elements include belts, chains, spur gears, keys, couplings, seals, bearings, clutches, brakes, electric motors, and fasteners. Strength of materials concepts and fi ts are applied to the shafts that carry these elements. Prerequisite(s): Complete MCDESG-106, MCDESG-130 and CIVIL-105. MCDESG-118 Credits: 3 Kinematics This course covers the displacement, velocity and acceleration of four bar linkages, slider-cranks, crank-shapers and compound mechanisms using graphical and design. Prerequisite(s): Complete MCDESG-106 and MCDESG-114. MCDESG-114 Credits: 2

analytical methods. Also covered are cam displacement diagrams, pro fi les, gear trains and epicycles. Prerequisite(s): Complete MCDESG-104 and CIVIL-105 and MATH-116 or MATH-202. Completion of or currently enrolled in MCDESG-106. MCDESG-120 Credits: 1 Basic AutoCAD Students are introduced to the use of AutoCAD software. The course is designed to be an introductory course enabling students to learn and apply computer-aided drafting (CAD) concepts relative to the preparation of construction drawings. MCDESG-124 Credits: 2 SolidWorks 2 This course introduces advanced solid modeling techniques using SolidWorks software with an emphasis on mechanical design. Topics include advanced modeling techniques in sweeps, drafts, blends, shells, and surfaces, advanced assembly techniques, sheet metal parts, and weldments. Prerequisite(s): Complete MCDESG-114. MCDESG-125 Credits: 3 Design Problems This is the capstone course for the Mechanical Design Technology associate degree. Students take the knowledge and skills acquired in other courses – Drafting, Statics, Strength of Materials, Machine Elements, Mechanisms – and apply them to a design project. Students select their own project and de fi ne the scope, the path of the completion of the project, perform necessary computations and complete all working drawings. Prerequisite(s): Complete MCDESG-106, MCDESG-114 and MCDESG-130. Completion of or currently enrolled in MCDESG-116. MCDESG-130 Credits: 3 Strength of Materials Students analyze internal stresses on linear members. The course focuses on axial, direct shear, torsional shear and bending stresses. These stresses are also combined using Mohr’s circle. Prerequisite(s): Complete MCDESG-160. MCDESG-133 Credits: 2 Inventor 1 This course introduces parametric solid modeling using Inventor software.
