MF3001 Design for Manufacture, Assembly and Environments Syllabus:
MF3001 Design for Manufacture, Assembly and Environments Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The main learning objective of this course is to prepare the students for:
• Applying economic process selection principles and general design principles for manufacturability in the development and design of products for various engineering applications. Also, apply design consideration principles of casting in the design of cast products.
• Applying design consideration principles of forming in the design of extruded, stamped, and forged products.
• Applying design consideration principles of machining in the design of turned, drilled, milled, planed, shaped, slotted, and ground products.
• Applying design consideration principles of welding in the design of welded products.
• Applying design consideration principles of assembly in the design of assembled products.
UNIT I INTRODUCTION
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
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
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 – Product design for manual assembly – Product design for automatic assembly – Robotic assembly.
UNIT IV COMPONENT DESIGN – CASTING CONSIDERATION
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
