Intro to CAD/CAM and Tools

What is Design?

Design is the human power to conceive, plan, and realize

products that serve human beings in the accomplishment of

any individual or collective purpose.

Usually considered in the context of applied arts ,

engineering, architecture, and other creative endeavors


3/26

Some Popular Design Approaches User-centered design, which focuses on the needs, wants, and

limitations of the end user of the designed artifact.

Use-centered design, which focuses on the goals and tasks

associated with the use of the artifact, rather than focusing on theend user

KISS principle, (Keep it Simple, Stupid), which strives toeliminate unnecessary complications

Murphy's Law (things will go wrong in any given situation, if yougive them a chance)

CAD/CAM

Computer-aided design (CAD) is the use of computer systems toassist in the creation, modification, analysis, or optimization of adesign.

Computer-aided manufacturing (CAM) is the use of computersystems to plan, manage, and control the operations of amanufacturing plant through direct or indirect computer interfacewith plants resources.


5/26

Need for CAD/CAM

To increase productivity of the designer

To improve quality of the design

To improve communications

To create a manufacturing database

To create and test tool paths and optimize them

To help in production scheduling and MRP models

To have effective shop floor control

Tools of CAD/CAM

AutoCAD (CAD) Computer Aided Design or Computer Aided Drafting

For 2D and 3D design and drafting, developed and sold by

Autodesk, Inc. in 1982

Earlier primitive entities used such as lines, polylines, circles,arcs, and text

But now it has solid modeling and 3D tools

Has supported custom objects through its C++ API

Application Programming Interfaces (APIs) for customization

and automation

Include AutoLISP, Visual LISP, VBA, .NET and ObjectARX

INVENTOR (CAD/CAE): Autodesk Inventor is a CAD software application for 3D

mechanical design, product simulation, tooling creation, and

design communication, developed and sold by Autodesk, Inc.

in 1999


18/26

MASTERCAM (CAD/CAM): Founded in Massachusetts in 1983, CNC Software, Inc

Let machinists design virtual parts on a computer screen and

also guided computer numerical controlled (CNC) machine

tools in the manufacture of parts

It has set of predefined tool paths

including contour, drill, pocketing, face, peel mill, engraving,

surface high speed, advanced multi-axis, and

many moreenable machinists to cut parts efficiently and

accurately
