MECHANICAL ENGINEERING TECHNOLOGY (ETME)

ETME 1101. Manufacturing Processes. (3)  This course surveys and introduces common manufacturing processes and design for manufacture considerations. Student will be introduced to methods and equipment used to transform materials, and to the interdependency between geometry (form), materials properties, and processes and their effects on functionality of the manufactured artifact. Coverage will include processing of polymers, metals, and ceramics. The purpose of this course is to provide the students the conceptual understanding of materials processes.

ETME 2101. Applied Materials. (3)  Prerequisite:  MATH 1103.  This course introduces the student to materials and to the concept that materials are designed to provide the desired properties in the same way that the parts themselves are designed. The students will learn to understand that the processes we use to change materials into the geometries we want for also change the properties of the materials. The course intends to approach materials from a design and manufacturing perspective.
