  1. A SEMINAR PRESENTED BY Ajaya Kumar Rath Regdno: 0901222007 Dept : ECE Sem: 7th

  2. ON COMPUTER AIDED PROCESS PLANNING

  3. CONTENTS….. • WHAT IS PROCESS PLANNING • NEED OF PROCESS PLANNING • INTRODUCTION OF CAPP • METHODS OF CAPP • VARIANT APPROACH • GENERATIVE APPROACH • WORKING PRICIPLE OF CAPP • CAPP IN DIFFERENT APPLICATIONS • ADVANTAGES OF CAPP • LIMITATIONS AND FUTURE SCOPE • CONCLUSION

  4. WHAT IS PROCESS PLANNING? RAW MATERIAL PROCESS PLANNING MANUFACTURING THE PRODUCT DESIGN FINAL PRODUCT

  5. Manual Process Planning • Traditional Approach • Done By The Expert Engineers depending on the past knowledge and experience.. • Product may not be qualitative

  6. Introduction To CAPP Computer maintained process plans Variant CAPP Generative CAPP

  7. Variant Approach Of CAPP PUT DRAWING (CAD) CODING & GROUPING OF PART FAMILIES TECHNOLOGICAL PROCESS OPTIMIZATION SETTING THE STANDARD TECHNOLOGICAL PROCESS PLAN FOR THE FAMILY

  8. Generative Approach Of CAPP • Introducing some artificial intelligence • Can recognize the parts automatically • Introducing decision rules and decision tables • Using complex algorithms. • Requires huge knowledge on database

  9. Diagramatic Representation Raw Materials CAD CAPP CAM Final Product knowledge database

  10. Applications Of CAPP CAPP is used in almost all industries like…. • sheet metal forming • Aircraft manufacturing • Paper industries • Automobile industries etc….

  11. CAPP in Aircraft Manufacturing

  12. Benefits Of CAPP……….. • Reduced process planning and production lead-times • Faster response to engineering changes in the product • Greater process plan accuracy and consistency • Inclusion of up-to-date information in a central database • Improved cost estimating procedures and fewer calculation errors. • More complete and detailed process plans • Improved production scheduling and capacity utilization • Improved ability to introduce new manufacturing technology and rapidly update process plans to utilize the improved technology

  13. STATISTICAL CALCULATION OF COST SAVINGS • 58% reduction in process planning effort • 10% saving in direct labor • 4% saving in material • 10% saving in scrap • 12% saving in tooling • 6% reduction in work-in-process

  14. Limitation Of CAPP ……. • Attaining a huge database for automatic reorganization is difficult. • Designing complex applications is somewhat costly.

  15. Conclusion Despite of the major challenges of automation technique CAPP is helpful in manufacturing the qualitative as well as quantitative products. In future the technique of CAPP will be used in purification and distinction of oil, manufacturing high profile spacecrafts and Nuclear weapons
