CNC fabrication estimator · 2026
A CNC fabrication estimator utilized a scatter plot dashboard to visualize the monthly co-movement of price changes between iron and steel and steel mill products. The visualization revealed a strong positive linear relationship with a correlation of 0.89, highlighting severe single-month price jumps reaching up to 16 percent. By accurately quantifying this extreme material cost volatility, the estimator successfully justified shorter quote validity windows and material-indexed pricing clauses to protect job margins during the supplier relationship management process.
