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

8. TECHNOLOGY Fortran. UNIX, Linux, Windows, Mac-OS X. Mouse, Graphics Tablet. Space mouse / Space ball Stereoscopic glasses 7 6

9. CAD-CAM Advantages Increased productivity. Error free drafting. Repeatability. Improved Collaboration. Lower overhead costs. Designs can be altered with minimal effort. It gives us a “zoom” feature similar to a camera lens. Three- dimensional modeling. Ability to create a sectional view. Generating G and M codes. 8 4

10. CAD-CAM Limitations Expensive software. Special Skills required. Expensive machines required. High maintenance cost. Nature of material of the object. 9 11
