JNTUK B.Tech Design For Manufacture (Departmental Elective – II) for R13 Batch.

JNTUK B.Tech Design For Manufacture gives you detail information of Design For Manufacture R13 syllabus It will be help full to understand you complete curriculum of the year.

Course Objectives

• Understand the design rules and considerations with reference to various manufacturing processes.
• To discusses capabilities and limitations of each manufacturing process in relation to part design and cost.
• To examine DFM principles including how the design affects manufacturing cost, lean manufacturing, six sigma, etc.

UNIT – I : Introduction: Design philosophy-steps in design process-general design rules for manufacturability-basic principles of designing for economical production – creativity in design.

UNIT – II : Machining processes: Overview of various machining processes-general design rules for machining-dimensional tolerance and surface roughness- Design for machining – ease –redesigning of components for machining ease with suitable examples. General design recommendations for machined parts.

UNIT – III : Metal casting: Appraisal of various casting processes, selection of casting process,-general design considerations for casting-casting tolerance-use of solidification, simulation in casting design-product design rules for sand casting.

UNIT – IV : Metal joining: Appraisal of various welding processes, factors in design of weldments – general design guidelines-pre and post treatment of welds- effects of thermal stresses in weld joints-design of brazed joints. Forging: Design factors for forging – closed die forging design – parting lines of dies – drop forging die design – general design recommendations.

UNIT – V : Extrusion & Sheet metal work: Design guide lines extruded sections- design principles for punching, blanking, bending, deep drawing-Keeler Goodman forging line diagram – component design for blanking.

UNIT – VI : Plastics: Visco elastic and creep behavior in plastics-design guidelines for plastic components-design considerations for injection moulding – design guidelines for machining and joining of plastics.
