CNC Machining (Computer Numerical Control Machining)

CNC Machining (Computer Numerical Control Machining) is a manufacturing process in which machine tools such as mills, lathes, and grinders are operated using programmed digital instructions rather than manual control, enabling highly accurate, repeatable, and consistent production of components. In…

APQP – Advanced Product Quality Planning

APQP (Advanced Product Quality Planning) is a structured, proactive approach to planning and controlling product and process development to ensure quality, safety, and conformity are built in from the outset. In an aerospace and AS9100 context, APQP focuses on early…

MSA – Measurement System Analysis

A structured evaluation of the accuracy, precision, repeatability, and reproducibility of measurement systems. Advanced MSA goes beyond basic Gauge R&R to include bias, linearity, and stability—essential where tolerances are tight and inspection data drives acceptance decisions. See also AS9100 and…

SPC – Statistical Process Control

A method of monitoring and controlling processes using statistical techniques (such as control charts) to ensure they remain stable, capable, and predictable over time. In aerospace, SPC is critical for early detection of process drift before nonconforming product is produced.…
