Course Objectives:

This course is an introduction to the rapidly growing fields of

CAD/CAM systems and aims to develop an understanding of

CAD/CAM related problems. The course has four main objectives:

1.   Understand the fundamental and advanced concepts in computer

graphics and computer-aided design

2.   Know the functions of a geometric solid modeler and how to use any

particular modeler for modeling an object and the different ways of manipulating it

3.   Understand the basics of NC-machine tools, and manual and

computerized part programming

4.   Learn what is process planning and how to integrate CAD with CAM.

Course Outcomes:

Students will demonstrate:

1.        An understanding of computer graphics systems and geometric modeling

2.        An understanding of curves and wire frame, surface and solid models

3.        An understanding of NC machine tools, CAD-CAM-CNC Systems

Integration, reverse engineering, rapid prototyping technologies.     

4.        An ability to write part programs for 2.5 D Milling, drilling and

turning cycles manually in the ISO Language system

5.        An ability to use a commercial CAD/CAM package including

the solid modeling and CAM modules effectively for simple

industrial parts to be milled, drilled and turned.

Grading:

2 Midterms                (40%)  Two midterms will be given during lecture hours. 

5 HW Assignments    (15%)  Five homework assignments will be given

                                 to promote and test understanding of CAD

                                 fundamentals and part programming.  In the term project,

                                 the students will develop the solid model of a 2.5-D part

                                 and generate the CNC part programs in the APT and ISO

                                 languages using a commercial CAD/CAM package. 

                                 Some of the midterm questions may be similar to

                                 the homework questions. Homework assignments

                                 will be prepared individually by every student.

1 Term Project          (%5)  Term project. Details will be announced later.

1 Final                       (40%)  Final exam will cover all the topics of the course
