ROI Calculation Logic

Assuming a 3% reduction in defect rate (from 5% to 2%) caused by residual stress in rod and wire processing. For a monthly production of 100 tons and a processing cost of ~$650/ton (AI est.), the monthly processing cost is ~$65K (AI est.). The loss due to defects would be ~$2K (AI est.) ($65K × 3%). This translates to an annual direct saving of ~$25K (AI est.). Including additional post-processing correction costs, reduced equipment load, and waste disposal cost reductions, an estimated annual manufacturing cost reduction of ~$200K (AI est.) is expected.
