Core/Elective - Core Course

To give students a basic understanding of the product cycle, hardware and software environment of Computer Aided Design/ Manufacturing (CAD/CAM) and necessary tools and techniques of CAD/CAM so that they will be able to design a total manufacturing solution for a given product and/or enhance the performance of a manufacturing entity.

At the end of this course, students should be able to:

1. Describe the product cycle and identify the CAD and CAM operations within the product cycle.

2. Identify the major components of a CNC machine.

3. Model a new concept or product by means of CAD tools and analyze the product by means of Finite Element method.

4. Choose the suitable CAD/CAM software and CNC machines for a given product.

5. Generate the part programs for a given product.

6. Use the CNC milling and turning machines to machine a given part.

1. Introduction: Challenges in manufacturing, history of CAD/CAM, product cycle, definition of CAD and CAM tools

2. CAD/CAM: Hardware: (Computer hardware, machine tools and components, hardware integration and networking), Modern technology of CAD/CAM, Evaluation criteria

3. Geometry/ Mathematical Representation: Curves, surfaces, solids, parametric representation Manipulations and applications, Data exchange (Formats: IGES, DXF, STEP, PDES, etc.)

4. Graphical Data Representation: Graphics standards, software modules, modeling and viewing, database, coordinate systems, transformations Manipulations and editing operations, primitives Algorithms for drawing entities, Animation interactive programming

5. FEM/ Modeling and Analysis: Modeling and mesh generation, Design and application
