  2. PROPOSAL • PERFORM COST ANALYSIS ON 2 DIFFERENT PROCESSES • MACHINING Vs. CASTING • DETERMINE WHICH PROCESS IS ECONOMICALLY BENIFICIAL BASED ON NET PRESENT WORTH ANALYSIS

  3. REQUEST FOR QUOTE • 4 FIN IMPELLER – PERSONAL WATERCRAFT APPLICATION • 6061-T6 ALUMINUM ALLOY • 3500 PIECES PER YEAR • MARR IS 12.5% • INFLATION IS 3.5%

  4. MANUFACTURING PROCESS • 5-AXIS HIGH SPEED CNC MACHINING

  5. MANUFACTURING PROCESS • MOLTEN ALUMINUM DIE CASTING • “SQUEEZE CASTING”

  6. CASTING Vs. MACHINING

  7. CASTING Vs. MACHINING

  8. SENSITIVIY ANALYSIS • FOR BOTH OPTIONS, CHANGE IN TOTAL INCOME HAD THE MOST EFFECT • 20% CHANGE IN INCOME RESULTED IN 30% CHANGE IN PRESENT VALUE (HIGH/LOW) • FOR CASTING, ELECTRICITY WAS SIGNIFICANT AS WELL (LARGER AMOUNT = HIGHER SIGNIFICANCE) • SALVAGE LEAST SIGNIGFICANT

  9. SENSITIVITY ANALYSIS

  10. CONCLUSION • WE CHOSE THE MACHINING PROCESS • EQUIPMENT COST AND MAINTENANCE WERE HIGHER BUT COST OF RUNNING OPERATION MUCH LOWER • HIGH REMOVAL AMOUNT OF MATERIAL MADE UP WITH RECYCLING RETURN • LONGTERM USEFUL LIFE • LABOR COST HIGH BUT LABOR MORE SKILLED AND VERSATILE • HIGHLY ADAPTABLE PROCESS
