ME3312 DESIGN OF JIGS, FIXTURES AND PRESS TOOLS LT P C
3 0 0 3
OBJECTIVES:
To understand the functions and design principles of Jigs, fixtures and press tools
To gain proficiency in the development of required views of the final design.
UNIT I LOCATING AND CLAMPING PRINCIPLES 8
Objectives of tool design- Function and advantages of Jigs and fixtures – Basic elements
– principles of location – Locating methods and devices – Redundant Location –
Principles of clamping – Mechanical actuation – pneumatic and hydraulic actuation
Standard parts – Drill bushes and Jig buttons – Tolerances and materials used.
UNIT II JIGS AND FIXTURES 10
Design and development of jigs and fixtures for given component- Types of Jigs – Post,
Turnover, Channel, latch, box, pot, angular post jigs – Indexing jigs – General principles
of milling, Lathe, boring, broaching and grinding fixtures – Assembly, Inspection and
Welding fixtures – Modular fixturing systems- Quick change fixtures.
UNIT III PRESS WORKING TERMINOLOGIES AND ELEMENTS 10
OF CUTTING DIES
Press Working Terminologies - operations – Types of presses – press accessories –
Computation of press capacity – Strip layout – Material Utilization – Shearing action –
Clearances – Press Work Materials – Center of pressure- Design of various elements of
dies – Die Block – Punch holder, Die set, guide plates – Stops – Strippers – Pilots –
Selection of Standard parts – Design and preparation of four standard views of simple
blanking, piercing, compound and progressive dies.
UNIT IV BENDING FORMING AND DRAWING DIES 10
Difference between bending, forming and drawing – Blank development for above
operations – Types of Bending dies – Press capacity – Spring back – knockouts – direct
and indirect – pressure pads – Ejectors – Variables affecting Metal flow in drawing
operations – draw die inserts – draw beads- ironing – Design and development of
bending, forming, drawing reverse re-drawing and combination dies – Blank
development for axisymmetric, rectangular and elliptic parts – Single and double action
dies.
UNIT V MISCELLANEOUS TOPICS 7
Bulging, Swaging, Embossing, coining, curling, hole flanging, shaving and sizing,
assembly, fine Blanking dies – recent trends in tool design- computer Aids for sheet
metal forming Analysis – basic introduction - tooling for numerically controlled
machines- setup reduction for work holding – Single minute exchange of dies – Poka
Yoke - Course should be supplemented with visits to industries.
(Use of Approved design Data Book permitted).
