Course summary
You will learn how geometric information about mechanical products is stored in computers, especially through Constructive Solid Geometry (CSG) and Boundary Representations (BRep). You will learn how commercial CAD/CAM systems use these models to perform the activities such as model creation, model manipulation and transformations, graphical display etc. You will learn about geometric issues relating to specific manufacturing applications. In particular we shall learn some details of computer-aided manufacturing planning, in the context of controlling 3-axis and 5-axis machining centers. Along the way, you will learn how to use a commercial CAD system (CATIA) and programming CNC machines in th RS274-language (n-g-code).
