WHAT IS PROCESS PLANNING?

DESIGN PROCESSPLANNING

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

ConclusionConclusion

Despite of the major challenges of Despite of the major challenges of automation technique CAPP is helpful in automation technique CAPP is helpful in manufacturing the qualitative as well as manufacturing the qualitative as well as quantitative products.quantitative products.

In future the technique of CAPP will be used In future the technique of CAPP will be used in purification and distinction of oil, in purification and distinction of oil, manufacturing high profile spacecrafts andmanufacturing high profile spacecrafts and
