Machining Plant Performance Sim

Castings flow from the raw store through turning, milling, deburr, robotic weld, leak test and pack. Operators, maintenance techs and a forklift work from live floor state. Every number on the page, from OEE to cost per unit to CAPEX payback, is computed from what happens on the floor.

From the floor to the P&L

Follow one story from an executive cost variance down to a single machine, then test the fixes and see which ones pay back.
