ROI Calculation Logic

Assuming a 20% reduction in processing time for hard materials compared to conventional mechanical polishing. For an average manufacturing line with annual labor costs of ~$200K (AI est.), consumables of ~$150K (AI est.), and equipment maintenance of ~$50K (AI est.), the reduction in labor and equipment operating costs is (~$200K + ~$50K) × 20% = ~$50K (AI est.). Additionally, a 5% improvement in defect rate due to higher precision is estimated to save ~$280K (AI est.) annually in material and rework costs. Total estimated annual cost savings could reach ~$350K (AI est.) per facility.
