Course Objectives:

This course is primarily an exposure to computer-aided engineering (CAE) that uses a commercial CAE package to demonstrate the various concepts. However, the course also introduces the topic of engineering design.

Engineering design is defined by the Accreditation Board for Engineering and Technology (ABET) as:

the process of devising a system, component, or process to meet desired needs. It is a decision-making process (often iterative), in which the basic sciences, mathematics, and the engineering sciences are applied to convert resources optimally to meet these stated needs.

Computer-aided engineering (CAE) aids in the design process by developing a computer-based description of a device or system that can then be used to drive other engineering applications such as drafting, numerical analysis (for example, finite-element analysis), and manufacturing (for example, numerically-controlled machining). For more advanced CAE, the engineer creates a parametric description allowing for the creation of device families and the integration of certain domain knowledge.

The specific application that will be emphasized in this course is drafting. Drafting techniques allow the engineer to communicate detailed creation and/or assembly information in a recognized, unambiguous and standard manner. The course will begin with students sketching three-dimensional objects and will end with a demonstration of parametric feature-based solid modeling and 3-D printing of a mechanical object. Although there will be lectures and assignments on three-dimensional modeling, the core of this introductory course will be on generating two-dimensional drawings of mechanical components.

By the end of the course, each student should be able to:

describe typical stages of an engineering design process and relate that to the design process used in Senior Design, MEEG401, at the University of Delaware;
use formal methods of engineering design to define an engineering problem:
- clarify needs/constraints,
- perform research/benchmarking, and
- develop preliminary specifications = metrics plus target values;
to allow subsequent comparison of concepts to be based on engineering and not just 'opinions;'
describe the difference between computer-aided engineering and computer-aided drafting;
generate sketches of three-dimensional objects;
define the parts to an engineering drawing;
explain the difference between assembly, layout and detailed engineering drawings;
create standard orthographic projections of three-dimensional mechanical objects;
create section views of three-dimensional objects;
apply basic dimensioning and tolerancing to an engineering drawing;
recognize geometric tolerancing on an engineering drawing;
explain the physical necessity for tolerances;
define three-dimensional parametric solid modeling;
create basic engineering drawings on a commercial CAE package:
- opening and saving,
- use absolute (world) and relative (local), Cartesian and polar coordinate systems,
- create standard drawing entities
- edit a drawing,
- create multiple views: orthographic and isometric,
- add dimensions and tolerances,
- create geometric tolerances,
- create a drawing package for a specific object = assembly, layout and detailed engineering drawings,
- create a solid model to interface the CAE package the Department's 3-D printer.

Homework:

Homework assignments will be given about every week. All assignments will be due in the TA's mailbox in 126 Spencer, no later than 5pm on the due date. Late assignments will be penalized 25% per weekday. Solutions should be posted one week after homework is due.

Quizzes:

Quizzes are given every Thursday at the start of the lecture. They are open book and open notes (your notes, not your neighbor's notes). They involve short answer, multiple choice questions to check on lecture and reading assignments and should take no more than ten or fifteen minutes to complete. In addition, they will be used for attendance.

Grading:
Grades will be posted on MyCourses Plus
