    • GROUP # 3 Muhammad waseem Saim khalid Zafar iqbal Muhammad imran 1
    • Agenda • • • • • • Manufacturing of connecting rod Forging Vs Casting Defects of forging Designing and manufacturing processes Limitation of forging Economics limitation 2
    • MANUFACTURING PROCESS FORGING CASTING 3
    • FORGING 4
    • Forging Vs Casting Forging Casting  Total processes approximate 16  Dimensional consistency and accuracy  Reduce mass by 10%  Consume less energy  Provides longer tool life  smoother running in the engine  Less cost for > 20,000 pieces  High production rate  Less time consumes  Reduce cost about 25%  It performed at low temperature  Total processes approximate 36  Less accuracy  More time consuming  Required high temperature for melting  Low production rate  Defects such as pin hole, shrinkage, porosity, Rough surface etc.  high cost for >20,000 pieces  More waste of materials  More labor cost  Machining process  Low strength 5

    • Selection of material  the connecting rods are most usually made of steel (for lightness and the ability to absorb high impact at the expense of durability)  titanium (for a combination of lightness with strength, at higher cost) for high performance engines, or of cast iron for applications such as motor scooters. 13
    • Cutting of material • Cut the material a little greater than the required due to further process heating billets • Billet is heated in the furnace at 500-600 ⁰C Hot forging • Hot forging is defined as working a metal above its recrystallization temperature. • The main advantage of hot forging is that as 14
    • the metal is deformed the strain-hardening effects are negated by the recrystallization process. piercing: 15
    • Trimming: Shot peening: Machining: 16
    • • Fracture splitting • Assembly • Insertion of bearing shell 17
    • • Insertion of bering bushes • Inspection 18
    • Limitation of forging • It must be enviourment friendly • It finished product cost must be moderate • Limitation of the mass deviation along the longitudinal axis • materials are generally less expensive than the materials required for casting. Limited scrap and rework. Reduced labor costs and lower tooling equipment expenses than casting 19
    • Economic limitation 20
