This document provides an overview of CAD-CAM (computer-aided design and computer-aided manufacturing). It discusses the history of CAD-CAM from its origins in the 1950s to its development and integration in later decades. The document defines CAD as using computers to aid the product design process, while CAM refers to using computers in manufacturing planning and control. It then covers the technologies behind CAD-CAM, its advantages like increased productivity and ability to alter designs with minimal effort, and limitations such as requiring expensive software and specialized skills. The document also lists several industries that utilize CAD-CAM and popular CAD-CAM software programs before concluding with thoughts on future developments in the field.
What is CAD?
Computer-aided design is defined as the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve design quality, document communication, and create databases for manufacturing. CAD uses computers to help design something in 2D (curves and figures) or 3D (curves, surfaces, and solids).

Design for Additive Manufacturing (DfAM)
DfAM - A generic term used to describe rules and parameters for a part design to be produced with an AM process
DfAM - is the practice of designing products to reduce or minimize manufacturing and assembly difficulties and costs,
DfAM aims
To take advantages of the unique AM technologies capabilities to design and optimize a product/component,
To utilize the characteristics of AM methods to improve the product/component functions according to the capability of the selected AM process.
In doing so, the designers should tailor their designs to maximize the advantages of AM methods, such as complex geometries and lightweight
Design Aspect and Design Consideration in AM
Design aspect
Any particular feature which can be quantified at the design phase.
Includes;
Geometric features of the part’s shape (overhangs, bores, channels, etc.)
Part’s programming parameters (layer thickness, orientation, etc.).
Design consideration
The result on the manufactured part
Specific properties of the process and quantified with certain key performance indicators.
These includes; surface roughness, accuracy, build time, etc.
Design Aspect and Design Consideration in AM
With conventional manufacturing processes, these aspects are mostly a concern for the production engineer rather than for the designer;
But, the significance of these aspects is high for the outcome in AM technologies.
computer-aided design and computer-aided manufacturing) refers to computer software that is used to both design and manufacture products. ... CAD/CAM applications are used to both design a product and program manufacturing processes, specifically, CNC machining.

5. INTRODUCTION CAD and CAM or CAM/NC generally stands for Computer aided design and Computer aided manufacturing numerical control respectively. Designing usually starts with CAD software where the actual drawing of the part to be machined is made which is followed by generating tool paths on CAM software. 4
6. DEFINITION OF CAD-CAM Computer Aided Design (CAD) is defined as the application of computer and graphics software to aid the product design from conceptualization to documentation. Computer Aided Manufacturing (CAM) is defined as the effective use of computer in manufacturing planning and control. 5 10
7. HISTORY In 1950’s the MIT’s servo mechanism laboratory established the concept of Numeric control(NC) on three axis milling machine. In 1960’s was that year in which Ivan Sutherland developed a sketchpad system on cathode ray tube.(General Motors announced their DAC-1 system and Bell Technologies introduced the GRAPHIC 1 remote display system). In 1980’snew theories and algorithms developed and integration of various elements of design and manufacturing made the existence of manual drafting almost extinct. 6
