WHAT IS PROCESS PLANNING? DESIGN PROCESS PLANNING MANUFACTURING THE PRODUCT

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

Computer maintained process plans Variant CAPP Generative CAPP

PUT DRAWING (CAD) TECHNOLOGICAL PROCESS OPTIMIZATION SETTING THE STANDARD TECHNOLOGICAL PROCESS PLAN FOR THE FAMILY CODING & GROUPING OF PART FAMILIES

Introducing some artificial intelligence Can recognize the parts automatically Introducing decision rules and decision tables Using complex algorithms. Requires huge knowledge on database

CAD CAPP CAM

CAPP is used in almost all industries like….  sheet metal forming  Aircraft manufacturing  Paper industries  Automobile industries etc….

CAPP in Aircraft Manufacturing

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

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

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

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 Nuclear weapons
