  5. 5. INTRODUCTION<br />CAD and CAM or CAM/NC generally stands for Computer aided design and Computer aided manufacturing numerical control respectively.<br />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.<br />4<br />
  6. 6. DEFINITION OF CAD-CAM<br />Computer Aided Design (CAD) is defined as the application of computer and graphics software to aid the product design from conceptualization to documentation.<br />Computer Aided Manufacturing (CAM) is defined as the effective use of computer in manufacturing planning and control.<br />5<br />10<br />
  7. 7. HISTORY<br />In 1950’s the MIT’s servo mechanism laboratory established the concept of Numeric control(NC) on three axis milling machine.<br />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).<br />In 1980’snew theories and algorithms developed and integration of various elements of design and manufacturing made the existence of manual drafting almost extinct.<br />6<br />
  8. 8. TECHNOLOGY<br />Fortran.<br />UNIX, Linux, Windows, Mac-OS X.<br />Mouse, Graphics Tablet.<br />Space mouse / Space ball <br />Stereoscopic glasses<br />7<br />6<br />
  9. 9. CAD-CAM Advantages<br />Increased productivity.<br />Error free drafting.<br />Repeatability.<br />Improved Collaboration.<br />Lower overhead costs.<br />Designs can be altered with <br /> minimal effort.<br />It gives us a “zoom” feature <br /> similar to a camera lens.<br />Three- dimensional modeling.<br />Ability to create a sectional view.<br />Generating G and M codes.<br />8<br />4<br />
  10. 10. CAD-CAM Limitations<br />Expensive software.<br />Special Skills required.<br />Expensive machines required.<br />High maintenance cost.<br />Nature of material of the object.<br />9<br />11<br />
