🔹 DPMO

Defects ÷ (Units × Opportunities) × 1,000,000


🔹 DPU

Defects ÷ Units


🔹 Yield %

Good Units ÷ Total Units × 100


🔹 Mean

X̄ = ΣX ÷ n


🔹 Standard Deviation

s = √[Σ(X−X̄)² ÷ (n−1)]


🔹 Cp

Cp = (USL−LSL) ÷ 6σ


🔹 Cpk

Cpk = Min [(USL−X̄)/3σ, (X̄−LSL)/3σ]


🔹 Z-Score

Z = (X̄−μ) ÷ (σ/√n)


🔹 X̄-R Chart

UCL = X̿ + A₂R̄

LCL = X̿ − A₂R̄


🔹 ROI %

(Financial Benefit − Project Cost) ÷ Project Cost × 100


🔹 Payback Period

Initial Investment ÷ Periodic Benefit


🎯 DMAIC:

Define → Measure → Analyze → Improve → Control

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : A BUG IN INJECTION MOLDING

Image
Today's KNOWLEDGE Share A bug in injection molding – an injection-molded part in a bug? Neither! Nature and injection molding have reached similar results. Nature created the first micro-gear long before any human engineering existed. One such example is the Issus coleoptratus (shown in the picture). Furthermore, only now are we reaching the point where injection-molded polymer microgears can approach this level of performance. Looking at the images, which one do you think is the natural gear, and which one is the molded version? It is not that easy to tell, right? Their appearance and operating principles are surprisingly similar. Chitin, a natural linear polymer, forms what nature essentially "molds” into shape. In engineering, we rely on advanced technical polymers to produce similar geometry through actual injection molding. They are not the same material, yet they solve the same issue: Stiffness, dimensional stability, and reliable function at a scale where tolerances...

Anti-Oxidant masterbatches protect the polymer chain, stabilizing it against thermal and oxidative stress. They are essential in polyolefins, engineering plastics, and films that undergo long processing cycles, ensuring durability, color stability, and consistent performance. source : Polimerizze Technology
