Introduction to CAD/CAM/CAE (Part I)

CAD/CAM/CAE

1.     Introduction

The computer has grown to become essential in the operations of business, government, the military, engineering, and research. It has also demonstrated itself, especially in recent years, to be a very powerful tool in design and manufacturing. In this and the following two chapters, we consider the application of computer technology to the design of a product. This section provides an overview of computer-aided design.

What do these acronyms mean?

CAD: Computer Aided Design

The use of computers to aid the design and manufacturing process

CAM: Computer Aided Manufacturing

The use of computers to develop the computer numerical control part programs for machining and other processing applications

CAM: Computer Aided Engineering

The use of computers to check the errors, do analysis and optimization process etc.

 

2.     What are the usages of CAD/CAM/CAE?

i)                    CAD: Computer Aided Design

•      The use of computers to aid the design and manufacturing process

•      2D/3D Drafting

•      Modeling Curves, Surfaces, Solids, Assemblies etc.

•      Engineering Drawing

•      Father of CAD/CAM? 

Dr. Patrick Hanratty: Created the first numerical control system, which would later become Computer Aided Design or CAD. The precision, versatility, and edit-ability of CAD designs revolutionized the Engineering architecture and manufacturing landscape.

ii)                  CAM: Computer Aided Manufacturing

·         The use of computers to aid the computer controlled machinery to automate a manufacturing process is a tool/program that uses numerical control (NC) to create detailed instructions (G-code) that drive CNC machines.

·          Generate tool paths and to control machine tools

iii)                CAE: Computer Aided Engineering

·         The use of computers to aid the computer to simulate performance in order to improve product designs assist in the resolution of engineering problems for a wide range of industries

·         To validate/test the product

 

3.     What’s the need of CAD/CAM/CAE?

i)                    To improve the quality of product

ii)                  To increase the productivity

iii)                To improve the communication between drawing, design and manufacturing

iv)                To create well data base for manufacturing

v)                  To improve the efficiency of the product

vi)                To save the lead time

vii)              To achieve best quality at less time

viii)            To achieve more accuracy

ix)                Customer modifications are easier to make

x)                  Minimized transcription errors

xi)                To reduce testing cost etc.
