3 0 0 3
UNIT I INTRODUCTION 5
General design principles for manufacturability - strength and mechanical factors,
mechanisms selection, evaluation method, Process capability - Feature tolerances -
Geometric tolerances - Assembly limits -Datum features - Tolerance stacks.
UNIT II FACTORS INFLUENCING FORM DESIGN 13
Working principle, Material, Manufacture, Design- Possible solutions - Materials choice -
Influence of materials on form design - form design of welded members, forgings and
castings.
UNIT III COMPONENT DESIGN - MACHINING CONSIDERATION 8
Design features to facilitate machining - drills - milling cutters - keyways - Doweling
procedures, counter sunk screws - Reduction of machined area- simplification by
separation - simplification by amalgamation - Design for machinability - Design for
economy - Design for clampability - Design for accessibility - Design for assembly.
UNIT IV COMPONENT DESIGN - CASTING CONSIDERATION 10
Redesign of castings based on Parting line considerations - Minimizing core
requirements, machined holes, redesign of cast members to obviate cores. Identification
of uneconomical design - Modifying the design - group technology - Computer
Applications for DFMA
UNIT V DESIGN FOR THE ENVIRONMENT 9
Introduction – Environmental objectives – Global issues – Regional and local issues –
