Low Scrap/Rework

The presence of scrap or rework or the absence of scrap or rework is the “result” of the effectiveness of your quality system, people, equipment, CNC program validation, and all the other building blocks structurally supporting scrap/rework on the Machining Pyramid. Every dollar spent on scrap and rework is subtracted from the profit as demonstrated through the hierarchical placement on the Machining Pyramid. Similarly, scrap and rework require equipment and personnel to replace the damaged product, which will result in lower on-time delivery, expediting cost in the form of overtime, shipping, and outside process premiums, and schedule disruptions to accommodate the repair and replacement.
